To any observer on the ground looking at the sky with the naked eye, the sky appears to be a vast spherical bowl, a celestial sphere that extends from all points along the horizon to the zenith, the point directly overhead. Astronomical objects seen in the sky are so far away that observers viewing them without the aid of a telescope have no intuitive sense of which objects are closer than others. This lack of depth perception causes everything to appear equidistant on the sky. Any object's position on this sphere can be determined by two coordinates, which designate the object's horizontal and vertical location. The vertical coordinate is determined by measuring an altitude angle upwards from the nearest point on the horizon, and the horizontal coordinate is established by measuring an azimuth angle from due north eastwards along the horizon to that nearest point. This system is called either the horizon coordinate system or the altazimuth system (see Figure 1). About 6,000 stars are visible to the naked eye when you can achieve the darkest conditions. The positions of the stars relative to each other remain fixed from night to night and year to year. In general, stars in the same area of the sky have no physical relationship to each other, but the very human tendency to impose order upon otherwise random distributions yields patterns of brighter stars, or constellations. Many constellations of the Northern Hemisphere have been inherited from antiquity, including Ursa Major, the Big Bear, of which the more familiar Big Dipper is part, and Orion, the hunter, which can be seen in the winter sky. Many Southern Hemisphere constellations were defined in the last century to fill in unlabeled regions of the sky. The sky is now officially divided into 88 constellations, which are used in modern astronomy for naming purposes. For example, the star alpha Ursa Majoris ( UMa) is located in the Big Bear constellation. Therefore, Ursa Majoris comes from the name of the constellation, Ursa Major, and the Greek letter indicates that it's the brightest star within that constellation. In addition to modern names, some 90 or so stars also have names from antiquity. For instance, UMa is also known as Dubhe. Over the course of the night, stars move across the sky from east to west as a consequence of Earth's rotation on its axis. The stars appear to move in circular paths around a celestial pole, or either of two points on the celestial sphere where the extensions of Earth's axis would intersect. In the Northern Hemisphere, the celestial pole is coincidentally marked by the relatively bright star alpha Ursa Minoris, also known as Polaris. Simple geometry shows that the altitude angle of the pole star above the northern horizon is equivalent to the latitude of the observer on Earth. To an observer in the Northern Hemisphere, stars that are always above the northern horizon are known as circumpolar stars; an observer in the Southern Hemisphere would see circumpolar stars around the south celestial pole. Stars that are further to the south and that rise and set sometime during the night are called equatorial stars. Equatorial stars rise in the east, move diagonally into the southern sky, achieving their highest position above the horizon on the meridian (the great circle that extends from due north on the horizon, through the zenith, to due south on the horizon). From the meridian, these stars move westward until they set below the western horizon. The celestial equator is that great circle formed on the celestial sphere by extending the plane of the Earth's equator. The equator intersects the horizon due west and due east. An immediate consequence of Earth's rotation is identifying the preferred directions of north, south, east, and west around the horizon, called cardinal directions, by which humans naturally orient themselves. Minute by minute, over the course of the night, both the altitude and azimuth of a star continually change. To more easily observe and track celestial objects, scientists have defined celestial coordinate systems that are fixed upon the sky and thus move with the stars. The equatorial coordinate system is a projection onto the sky of Earth's latitude and longitude coordinate system. Celestial latitude, known as declination, is the angular position north or south of celestial equation. Celestial longitude, measured around the celestial equation, is known as the right ascension (see Figure 2). Declination is measured in degrees, minutes of arc, and seconds of arc. Recognizing that the stars appear to move once around the sky in one day (24 hours), right ascension is measured not in degrees, but in hours, with 24 hours of right ascension (to distinguish from 24 hours of time) equal to 360 degrees. Like the stars, the Sun rises and sets every day. However, unlike the fixed motion of the stars, the Sun's daily path across the sky varies throughout the year. Twice annually, at the vernal equinox (about March 21) and the autumnal equinox (about September 21), the Sun's position coincides with the celestial equator; it rises due east, moves across the sky following the path of the equator, and sets due west (see Figure 3). At this time of year, the length of the day is the same as the length of the night. During the summer, however, the solar position is north of the equator, achieving a maximum northernmost declination of 23.5 degrees at the time of the summer solstice, around June 21. In the winter, the solar position is reversed, with the Sun at its maximum southernmost declination of -23.5 degrees at the time of winter solstice, December 21. The terms equinox and solstice mark not only specific times of the year, but also specific points in the sky. The vernal equinox is that position on the celestial equator where the Sun crosses from the southern into the northern sky. Celestial longitude (right ascension) is measured eastward around the equator from this point. The Sun's seasonal positions in the sky. Relative to the background stars, the Sun also moves about one degree eastward each day, thus encircling the sky in the course of a year. This ecliptic, or the great circle on the celestial sphere defined by the solar path, is tilted with respect to the celestial equator by 23.5 degrees. Throughout the year, the ecliptic passes through the 12 zodiacal constellations. Because the apparent solar movement is caused by Earth's motion around the Sun, the ecliptic plane is also a projection of Earth's orbit about the Sun. That Earth's rotational equatorial plane does not perfectly match its orbital plane (the ecliptic plane) about the Sun is directly responsible for the annual northsouth movement of the Sun and the consequent seasons. The length of the year is based on the time that the Sun takes to complete its annual path around the sky. During the year, the stars and constellations visible at night change as the seasons pass through their cycle. A year is, in fact, 365.25 days long. To keep the calendar in sync with the actual seasonal passage of time, every four years we have a leap year, or a year of 366 days. The additional day, February 29, makes up for the time lost annually when the 365.25 day cycle is computed as 365 days. The length of a day is based on the time it takes for the Sun to complete its daily path across the sky, from its crossing of the meridian at noon to its next crossing of the meridian the next day. Daily time based on the hourly position of the Sun in the sky, relative to its noontime position each day, is called apparent solar time. To astronomers studying the stars, however, the time of day alone is not a sufficient method for determining which stars can be observed at any given time. Astronomers need to know both the time of day and where the Sun is in the sky to find out which stars they can observe. More specifically, what is of interest to an astronomer is the sidereal time, or the right ascension of the stars that are crossing the meridian at any moment. Sidereal time and solar time are not equal because of the annual motion of the Sun across the sky. The true rotation period of Earth is 23 hours, 56 minutes, but the length of the day is four minutes longer. In one rotation of Earth, the Sun has moved roughly one degree across the sky, thus Earth has to rotate a little bit longer to get the Sun back to the same position on the sky. The solar day is 24 hours long. The actual length of any given day varies throughout the course of the year for two reasons. First, Earth's orbit around the Sun is not a circle, but an ellipse. The Sun's apparent motion across the sky therefore varies slightly, moving more than the average one degree per day in January, but a bit less than the average in July. Second, the solar motion along the ecliptic moves parallel to the celestial equator at the times of the solstices when the Sun is farthest north or south of the equator, but at the times of equinoxes, its motion is at an angle to the celestial equator. What is important for the length of the day is only that part of the solar motion parallel to the equator. This produces a second variation to the length of the day. The difference between apparent solar time (which would be shown by a sundial) and mean solar time (which would be shown by a clock or watch) is called the equation of time. This is a complicated effect involving orbital mechanics (the motion around an ellipse is not uniform), perspective (a moving object closer to the observer has a greater apparent motion), the tilt of the ecliptic to the equator (hence the daily component of solar motion across the sky varies from equinox to solstice), and a geometrical factor resulting from the fact that we are dealing with a spherical coordinate system; this latter you can demonstrate to yourself by placing your thumb on the equator of a globe. Note how much longitude angle it covers. Now place your thumb near the north pole. Your thumb will cover the same area, but as measured in longitude, it covers a much bigger longitudinal angle. And it's that angle that is important for rotation and hence the length of a day. Noon, as defined by mean solar time, can occur as much as 16 minutes late in October or 14 minutes early in February compared to the Sun's actual crossing of the meridian. Observation of the Moon shows that it not only appears to change its position by moving around Earth, but at the same time, the fraction of its surface that is illuminated by sunlight (its phase) also changes (see Figure 4). When the Moon is directly opposite the position of the Sun, it appears totally illuminated, or in full phase. When the Moon is viewed at an angle of 90 degrees from the position of the Sun, its surface appears half illuminated, or in its quarter phase. Between full and quarter Moon, the phase is said to be gibbous. If less than half the Moon is illuminated by sunlight, the phase is crescent. When the Moon is in the direction of the Sun and the side toward Earth is its dark or shadowed half, the Moon is said to be new. The cycle from new Moon waxing (increasing illumination) to first quarter to full Moon, then waning (decreasing illumination) to third quarter and back to new Moon takes 29.5 days, a period adopted as the basis of our calendrical month. The lunar phases are observed because of the changing geometrical orientation between the Sun, Moon, and Earth over the course of the lunar month, not the result of Earth casting its shadow on the Moon. The Moon takes 27.3 days to move once (360 degrees) around Earth as determined by its orbital position relative to the stars; the orbital period is therefore also an example of a sidereal period, a period measured relative to the stars. This 27.3 days can also be called a sidereal month. The time from full Moon to full Moon is longer, 29.5 days, because two motions are involved: the motion of the Moon around Earth and the motion of Earth around the Sun. To become full again, the Moon must move more than 360 degrees around Earth. The lunar month, or lunation, is thus an example of a synodic period, or a period produced as the consequence of two motions. The term synodic month is also applied to this 29.5 day period. Another example of the difference between a sidereal period and a synodic period is the rotation of Earth (23 hours, 56 minutes) and the length of a day (24 hours). The actual path across the sky of the Moon is quite complicated. The lunar orbital plane is tilted about 5 degrees 9 minutes with respect to ecliptic plane. The orientation of these two planes rotate with respect to each other over an 18.6 year period. In consequence, relative to the celestial equator, the lunar orbital plane has a variable tilt that periodically oscillates from 23.5 degrees minus 5 degrees 9 minutes equals 18.3 degrees, to 23.5 degrees plus 5 degrees 9 minutes equals 28.7 degrees. In other words, over the course of the month, the Moon can oscillate north and south across the celestial equator between declinations of as little as 18.3 degrees to as much as 28.7 degrees. Each month the path of the Moon across the sky differs slightly from its path the prior month and from its path the next month. In contrast, each year the solar path around the sky is essentially the same. Astronomers find particularly interesting the two intersection points, or nodes, between the great circles of the ecliptic plane and the lunar orbit. If the Sun and Moon in their motions about Earth move simultaneously through nodal positions, an eclipse occurs (see Figure ). If the Moon and Sun are at the same node, the Moon passes in front of the Sun and a solar eclipse results, lasting only a few minutes in duration. If the two are at opposite nodes, then the Moon passes through the shadow of the Earth and a longer duration lunar eclipse occurs. The cycle of occurrence of eclipses is quite complicated because three factors are involved. The Sun moves around the sky in 365.25 days. The Moon moves once around the sky every 27.3 days. The direction to a node (where the two orbital planes intersect) moves around the sky in 18.6 years. To get an eclipse, all three positions (Moon, Sun, and node) have to be along a straight line through Earth. This event does not happen with a simple pattern of regular time intervals. Nakedeye observers in antiquity recognized five other objects that move across the sky relative to the stars - the planets. The word planet comes from the Greek, meaning "wanderer." Planetary motion is more complicated than that of the Moon or Sun, which move systematically west to east relative to the stars. The planets' usual motion is west to east, termed direct or prograde motion. But in each synodic period, planets show a brief period of motion in the opposite or retrograde direction. Retrograde motion is the result of perspective. Consider, for example, driving on a freeway. You look forward toward a slower moving car. Relative to the distant mountains, it is clear that this car is moving in the same direction you are moving. But as you catch up to and bypass the slower car, you see it appear to be moving backwards compared to the distant horizon. As you pull ahead, once again looking back at the slower car shows it to be moving forward. Observation of other planets from Earth produces the same apparent reversal of motion relative to the background of stars. (See Figure 6).

In short, if you are looking for a special light fixture, then stop running around, just type www.ledmyplace.com on Google, and you will surely find an answer to your queryBest Outdoor Solar SpotlightsOne fairly recent innovation in home lighting equipment is the advance of outdoor solar spotlights. In the past many homeowners would have liked to take advantage of outdoor lighting for both decoration and security, but the cost of running outdoor wiring was prohibitive. Hiring landscapers or electricians to string power around your property just was not worth it. But recent advances in solar technology and LED lighting made high quality outdoor solar spotlights affordable and easy to install by almost anyone. As a result, more and more homeowners are enjoying the added safety and beauty of strategic and decorative lights. Of course, not all solar spotlights are created equal. Cheap units can under perform and cost you more in the long run. To help you avoid making a poor choice, we put together this solar spotlight review. For those in a hurry, here are the units we looked at: The field of solar spotlights available to consumers continues to grow. To help you find the right ones for your situation, we went over the top units on the market. We compared features and analyzed owner feedback to help weed out the poor performers. From that research we came up with these picks for the best outdoor solar powered spotlights: These solar landscape spotlights come in a four pack of completely adjustable LED lights with a total of 600 lumens. The included solar powered 18650 rechargeable lithium ion batteries allow for a long-lasting solar charge. These fashionable and practical solar spotlights have 2 brightness modes: Low Light produces 12 hours of use and High Light allows for 6 hours of light output to accommodate all your lighting needs. These solar landscape spotlights ensure automatic detection of brightness and motion, automatically changing from energy storage mode to lighting mode in an instant. They are very durable and are made of high-impact ABS plastic. They boast a unique IP67 waterproof design that can withstand all types of weather and are heat resistant. They are easy to assemble, and you can install them in the ground or wall mount with the included hardware. A repeat customer said all you have to do is just open the box, push in the stake, set the light mode to high or low, tighten or loosen the knob to adjust the angle, plant and enjoy. The 120-degree lighting angle and 90-degree adjustable solar panel angle allows you to adapt the lighting for your needs and modify the position of the solar panel for maximum coverage and light output. The streamlined one-piece design also makes it a cinch to mount to any surface. Just make sure to follow the directions included in the packaging and charge before using. One user noted that the solar landscape spotlights can turn on and off when pulling in the driveway at night with headlights on, but this was to be expected and was only a minor inconvenience. One customer stated these lights must be placed in direct sunlight and may not be as bright if they are not able to charge properly. Another concern is that these cannot be pointed downward because they do not bend beyond a horizontal position, so make sure to keep this in mind during placement as it can affect their performance. This four pack of solar lights make great waterproof outdoor landscape lighting or can be used as spotlight wall lights. They have an auto on and off feature that instinctively detects changes in the environment and switches on and off as needed. They feature a high conversion rate, with 200 lumens output by four super-bright LEDs that are strongly sealed and omit white light. The solar panel and light are independently adjustable - with the light head being adjustable to 90 degrees. The 2200mAh lithium-ion rechargeable 18650 batteries are included for fast charging. There is a separate, fully adjustable light and panel with two lighting modes: Low for 8 to 12 hours of light production and High for light lasting 4 to 6 hours. Many users stated that the button is sealed really well, and the plastic ABS housing makes them waterproof and heatproof to withstand any weather conditions. You can stake these solar powered spotlights into the ground or mount them to any exterior or interior surface with the included hardware. This upgraded version has a lengthened stick to insert deeper in the ground for greater stability during the highest of winds or harshest of environments, enhanced brightness, and the solar panel and battery capacity have been enlarged. They look great in daylight and super bright at night, and customers rave about their simple assembly and easy, no-hassle installation. As with many solar spotlights, working time for this model is weather sensitive. One user warns that the switch must be turned on upon initial setup before use and another that the solar spotlights are a bit bulky. There is limited adjustability because of the non-pivoting solar panel, so positioning matters. One reviewer advises to move them around until you get the look you want. These solar outdoor lights come in a two pack and have an upgraded solar panel measuring a whopping 15.3 square inches. There are three lighting modes: Security with a motion sensor that can detect up to 26 feet within a wide 120-degree angle, Permanent On, and Smart Brightness Control. The third setting is a permanent light on in dark conditions, then it gets brighter for 15 seconds when motion is detected so it wo not bother your neighbors, and if motion continues it stays on. These features also help to conserve battery time, making the light emitted last longer. The included 2200mAh lithium ion 18650 solar rechargeable batteries power PET laminated solar panels and premium LED lights. A customer stated that the solar outdoor lights can last about 6 hours in the summer and 3 hours in the winter after an average day of charging, which can be more on full-sun days. The IP65 technology makes these sealed solar outdoor lights waterproof and heatproof to protect the whole device from the elements. Many customers liked that they can be attached anywhere. One gentleman says you can tie it to a fence, fasten them to a tree, or attach them to a deck or post. They come with sheetrock anchors and screws for easy installation in a closet or a back entrance, just follow the easy instructions for installation and placement to receive maximum sunlight. Also, a buyer cautions that the switch located on the back of the device can be inconvenient, so just make sure to choose the setting you want before permanently mounting. One customer was concerned that the lights can often go out due to cars or pedestrians with flashlights passing by them and there is no adjustment you can make on the device itself to rectify this issue. Otherwise, they were very satisfied with their purchase. Another individual states that the solar panel is always at an angle and cannot be faced straight up. Also, these lights may require additional hardware to install that is not included, like galvanized steel screws to protect from rusting. The four included outdoor solar spotlights feature 200 lumens LED lights that omit a warm white light. The light is always on, but there are two modes: Low and High. Light lasts for 6 to 10 hours after a full charge of the included lithium ion batteries. There is a dusk-to-dawn sensor, which receives environmental feedback to turn the lights off and on in times of low or high light coverage. The fully adjustable light and solar panel allow for maximum coverage and charging ability. The light angle can adjust up to 180 degrees, and the solar panel angle adjusts up to 90 degrees for optimum sun exposure. One customer was surprised how easy setup was, because you can quickly stick them in the ground using the included sturdy posts or wall mount in a few minutes with the included hardware. These outdoor solar spotlights are water resistant, heat resistant, and frost resistant. So, they are safe to use during rainstorms, snowstorms, or extreme heat and humidity, making them an ideal option for all climates. One reviewer mentioned to make sure to turn the manual on and off switch located on the back of the solar panel to the on position before installing and remarked that their lights stay lit for up to 8 to 10 hours on a normal day's charge. Another buyer remarked that the plastic used is not high quality and the lights could require additional silicone caulking to be truly waterproof. These 2-in-1 adjustable solar spotlights emit a warm welcoming light with four LEDs producing a total of 200 lumens. They come in a two-pack and have an automatic on/off sensor that will turn the lights on and off depending on the amount of light it is exposed to. The lights can be wall mounted with the included hardware or staked into the ground. A customer commented that setup was very easy - just attach the included stem to the light and insert it into the ground where you want it. After some simple repositioning, they were casting light on the areas they wanted. They are made of waterproof and heatproof ABS material to tackle any weather Mother Nature can throw at them. These solar spotlights are adjustable up to 180 degrees for the light and solar panel. Both the light and solar panel have their own easy to set vertical angle adjustments. The 2200mAh lithium-ion battery can function 6 to 9 hours after a full solar charge. There are two brightness modes: Low and High for strong and powerful bright focus, and a large solar panel for prime charging. One reviewer suggests for best results, these lights should be charged for 8 hours and must be installed in an area that receives full sunlight every day, otherwise, the battery will not fully charge and this will reduce the amount of illumination produced. Another customer voiced concern that the lights produce more of a spotlight effect, that the light path is a bit narrow and not a floodlight pattern as they would prefer. Otherwise, these solar spotlights met their needs and exceeded their expectations. Outdoor Solar spotlights typically have three main parts: a set of lithium-ion rechargeable batteries, a light housing using LED or another high quality and high output lighting source, and a solar panel to catch the sun's rays. During daylight hours, the solar panels capture the sun's energy and then stores it in the lithium-ion batteries. During the evening or when it is dark, the rechargeable batteries power the spotlights. The amount, duration, and quality of light they emit depend upon the amount of charge they can hold and the amount of sunlight they are able to be exposed to. For this reason, it is extremely important to place the outdoor solar spotlights in an area that receives maximum exposure to sunlight for optimal light production. The solar panel may be attached directly to the top of the light housing or it can be attached to the back of the light and protrude upwards and away from the lighting shroud. They come in all shapes and sizes, from spherical to rectangular and small to large for a variety of applications. Oftentimes, solar-powered spotlights can be used indoors or outdoors. Many models come equipped to be installed in the ground using a stake or pole and can also be used indoors or on the sides of buildings or other structures by mounting on a wall or other surface using screws. They also happen to use technology that makes them usable in any weather situation, from the desert heat of the southwest to the brutal winters of the northeast. They have sealed and enclosed cases to keep the elements out. Thus, solar powered spotlights require minimal effort for installation and upkeep. Many models feature automatic dimming or motion sensing characteristics. Many models we reviewed had capabilities of sensing motion up to 50 feet or more away from the installed unit, but this depends on where the lights are installed and what angle capability they possess. A good solar powered spotlight will be able to be adjusted and positioned in a variety of ways and will also have options and modes for brightness or intermittent light exposure. Outdoor Solar spotlights look professional and cost much less than a quote from a landscaper for their wired counterparts. People have reported spending thousands of dollars on entire wired landscape lighting packages, only to discover later that they could have saved money and time if they had just purchased solar powered spotlights and installed them themselves. And you do not have to pay a landscaping company or electrician for upkeep or repairs when an issue arises. An added bonus of using solar powered spotlights is that they can help save you money on electric bills. Many users describe a reasonable decrease in their use and cost of electrical services after installing solar powered spotlights. You no longer have to keep your front or back porch lights on and bother your neighbors with unwanted light coming in their windows all night. For those concerned for the greater good of mankind, these lights also lessen environmental impact by not wasting electricity. They only use what energy they have stored, and many feature an automatic on and off that allows for the lighting fixture to conserve energy when not in use during daylight hours or when intermittent lighting is present. Solar powered spotlights are virtually hassle free. Since these spotlights are wireless, this means no rodents or other animals can wreak havoc on your landscape lighting by chewing the wires - there are none! This also means you do not have to worry about underground wiring when moving objects or replanting in your garden or yard. Here is a good YouTube video that discusses how a set of solar spotlights hold up over time: What are Outdoor Solar Spotlights Used for? Solar spotlights have a variety of applications. They can be enjoyed as an accent to highlight target areas, making them an excellent decorative accent to landscaping features. You can mix warm and cool white lights to add contrast and depth to your landscaping for a dramatic or romantic feel. Use them to light up house numbers for better visibility from the street, or for the main lighting for your yard, garden, driveway, porch, walkway, pool, garage, and patio. Because of their relatively small size and compact design, they really are ideal to place anywhere you want and need light. Outdoor solar spotlights can also provide you and your family with the safety and security of sight in the darkness. Nowadays, porch pirates feel free to come on people's property and steal packages or expensive landscaping features. By using spotlights with a high lumen rating, you can deter thieves and those wishing to do others harm. You can add them to your home for an economical indoor lighting choice. They can easily be installed in closets or areas of your home that receive very little exposure to the sun or daylight. One traveler expressed his opinion that they could be used almost anywhere, as he uses outdoor solar powered spotlights as the main light source for his motorhome or RV for added visibility while camping.

Not only is it a strong piece, but it also has a super sleek and modern design that is sure to complement any type of outdoor decor you might have around your home. The BlackLemon solar spotlight is another reliable option for any kind of landscaping around your home, as well as to improve the safety of your home. They work best at close range but can be used at slightly longer distances as well. They can be placed in the ground as accent lights or mounted on the wall for added security and come two in a pack. If you choose to mount your spotlights on a structure, the hardware is included. These lights are fully adjustable, rotating 180 degrees so that the lights can be charged by the sun no matter where they are located outside. They should last you about 10 hours with a full charge, perhaps a bit less without access to full sunlight or on the higher of the two settings available. Their appearance is very similar to that of #1 on our list, but the color of the light is more of a cool bright white shade, but these are likely the best bright white solar outdoor spotlights available. The lights are waterproof and heatproof too, so they will be able to handle any severe weather conditions that may come your way. If you ever need to move these solar lights, it's simple and convenient because the solar panels are attached to the lights. These are also a really affordable option and if for some reason you are unable to obtain enough sunlight, it comes with a rechargeable battery. If you are looking for solar spotlights that are a little less noticeable than some of the others mentioned in this article, these twin lights by Solar Light Mart are an awesome choice. Do not let "mini" fool you, because these are surprisingly bright for their size. Each light fixture contains 60-100 lumens, which is lower than some of the other choices out there, but again they are still considerably bright. They have a warm white glow that is suitable for a variety of outdoor uses. Plus, there are three brightness settings so you can change them accordingly. They last anywhere from 5-15 hours, but it's dependent on which brightness setting you have them on. The lower the brightness, the longer they last. I love that these have sturdy aluminum stakes as opposed to the plastic ones that a lot of other solar spotlights have. These mini spotlights also come with a large remote solar panel, which makes it easier to gather a lot of sunlight from anywhere in your yard. They are more expensive than some of the others listed and can be purchased as one pair per pack, but they are well worth the cost. The Nekteck Solar Powered Garden Spotlight is ideal for those looking for something with a warm glow that they would like to put in a garden, but it's a good option for outdoor porches, patios, signs, driveways, or walkways too. These lights put out 200 lumens per light, which is equivalent to 50 per LED bulb. This is their 4th generation spotlight available so it is an improvement from previous versions. They give off a slightly yellower tint than some of the other warm white options in this list. It's more of a low-voltage look, rather than a super bright LED look. Despite its super warm and inviting hue, it's still pretty bright but yet very easy on the eyes. These would probably work better as accent lights rather than as an added security feature because of their yellow appearance. As with a lot of the other outdoor solar spotlights mentioned in this article, this one is also wall-mountable, or you can simply stick the stake in the ground. Both the stake and the wall-mounting hardware are included with the lights. This is the first solar spotlight on our list that does not have multiple brightness settings, but it definitely does not lack in performance. They last approximately 6-10 hours once charging is complete. They work best in full sunlight, which is to be expected but will also work relatively well after an overcast day. If you are looking for spotlights that shine crisp, clear, and bright white, the Innogear may be an excellent option for you. They work fabulously for all types of landscaping and safety needs: lighting a walkway or driveway for visitors, mounted on a wall for added security, or showing off beautiful trees and plants in the yard or garden. Screws are included so that you can mount them if you choose, and the stake goes deep enough to remain stationary. These lights work best if you have access to 4-5 hours of sunlight, which will give you long-lasting, aesthetically pleasing light throughout the night and into the next morning. If you do not have access to a lot of sunlight on a particular day, there is also a rechargeable battery. They come in a pack of four and contain four LED blubs that output a total of 200 lumens in each individual light. The solar panels are also fully adjustable so that they can be angled to the best possible position for the maximum amount of sunlight. To assemble, simply attach the plastic stake to the light. The URPOWER is a reasonably priced choice for those that are looking for a cool white light, which has a very slight blue tint. There is a high and low setting so these lights work well as a main light or an accent light. These can be stuck into the ground with the included stake or mounted on a structure with the hardware that is included. The stake deep into the ground so that the light stays still against the elements. In contrast to the conical shape that many other solar spotlights have, these lights are rectangular shape and contain six LED bulbs, at a 200 lumen output per light on the high setting. I think this shape gives the lights more of a commercial appearance, rather than a residential appearance. So these would likely work best along walkways or driveways, or mounted on a structure such as your home, shed, or garage for additional home security. They work stunningly from a distance if you would like to illuminate a larger area, such as the front of your home. They would even work nicely to show off landscaping such as trees, plants, and flowers at night. Because of the appearance of these lights and their durability I would highly recommend using them for additional security to your property. These lights also have a rechargeable battery option if you do not have full access to sunlight. They are resistant to different types of weather such as heavy rain. In contrast with other lights listed, this option specifies a one-year warranty, which is an excellent added bonus in case of any possible issues throughout the life of the light. URPOWER also offers lifetime customer service if you ever have any issues with your solar outdoor spotlights. The SOLVAO Solar Spotlight offers a sleek and modern design, even it boasts an extra-large solar panel. The solar panel is also frosted to keep it free of dust and dirt. These solar spotlights can be mounted anywhere, or placed in the ground with the sturdy plastic stake if you choose and have a good range of motion so that you can angle it any way you would like. This is the third generation model of this spotlight, so it is an improvement of previous versions available. This is another super bright option that will illuminate a variety of areas such as gardens, walkways, driveways, decks, pools, etc. It also works really well to illuminate areas upwards, such as trees and flagpoles. These are 200 lumen output spotlights, which equates to 50 per LED bulb, so they are also a good choice if you are looking to have added safety and security to your home. Assembly is super simple; all you have to do is attach the stake and place them wherever you need. These lights will turn on automatically when it gets dark, and turn off when the sun rises. The low setting will allow the light to function for even longer periods of time, as with other solar lights. SOLVAO specifies that this would be a great solar light to take with you if you go hunting or camping. In addition, it's got a rugged, weather-resistant body that will withstand many types of weather such as heavy rain, blowing snow, and high heat. As with some of the other spotlights in this article, it's also a great low-cost choice to light up your life. You wo not be sacrificing practicality for affordability. These VicTsing solar spotlights are made of rugged plastic and are large and sturdy enough to handle any weather, all year-round. They are fully adjustable and come in a pack of 4. The light has the ability to adjust 90 degrees, while the solar panel can be adjusted 180 degrees which is convenient so you can angle them pretty much any way you want. The stakes are also long enough that when positioned into the ground they will stay put. They contain four LED bulbs in each light; each light is 50 lumens. They are bright enough to light up the front of a house for added security but are also suitable for use along a driveway or walkway, and anywhere else outdoors that you may need them. The lights are a cooler white, but not so much so that they have a blue appearance. Once these lights are charged, you can get approximately 6-9 hours of use out of them. They have two different light intensities for your convenience. The low setting should last through the night and into the morning, but the high setting may not last the whole night. This set is one of the more expensive options listed, but if you are searching for something that comes four in a pack, they are going to be a decent choice. The W-Lite solar spotlight comes in two different colors: Daylight and Warm White. Both are suitable for a variety of uses: in the garden, in front of bushes, under flags or trees, in front of the house, or along a walkway. They come with a large solar panel attached by a 9.8 ft. cable and are perfect if you do not plan on spreading them extremely far apart. However, they still offer plenty of flexibility and convenience for placement anywhere on your property. For example, the lights can be placed in a shady area to accent bushes or trees, and the solar panel can be placed in an area that is more apt to receive a lot of sunlight. Ideally, the solar panel should be in direct sunlight for around 6-8 hours for optimal use. Alternatively, the lights are also rechargeable-battery-operated with a lifetime of up to 5000 hours. These lights only come with one brightness setting, which sets them apart from many of the other solar lights that can be purchased. Despite this, it's still got a decent level of brightness to be used in a variety of ways. The housing for the lights is made from aluminum, which makes it satisfactory in even the worst weather. On the other hand, the solar panel itself is made of durable plastic. The lights also come with an adjustable bracket for easy wall-mount installation and can be adjusted 90 degrees. If you are looking to purchase something with a square shape, rather than the conical shape like many of the others listed in this article, the Aptoyu could be a good fit for you. As with the URPOWER, discussed above, the square shape of these lights gives them more of a commercial appearance and less of a residential appearance. It's all a matter of personal preference. The shape of these lights allows 9 LED bulbs (20 lumens per bulb) to be housed inside the weather-resistant casing, making for maximum brightness potential in this particular light. The total lumens per light totals to be slightly less than some of the other solar lights listed in this article, but it puts off a decent amount of light. There are two levels of brightness that you can choose to use with these lights. You should get around 4-6 hours of light with the high setting, and about 8-12 hours on low mode. One press of the button turns on the low setting and the second press of the button turns on the high setting. The light and solar panel on these units tilts up and down so that it can more easily be aimed at the sun, but it is not fully adjustable like some of the other models that have been listed. These lights would probably be appropriate for use under a flag pole, in front of an address sign, or mounted on the wall for security reasons. The hardware needed to mount them to the wall is included in the package. Hopefully, this article has helped you understand the different outdoor lights available out there and find the one that will be best suited to your needs. At the very least, you have a list of the best options on the market to help you make an educated decision before purchasing. Solar lights are a wonderful addition to any outdoor space and can make beautiful landscape and safety improvements to your property. Do not forget, they can save lots of money on electric bills and they have environmental benefits too.

This is very rare to see in someones acting career------2. Why did the BJP government select a young face against one of the most formidable candidate Arvind Kejriwal in the Delhi election? Do they not want to win the Delhi election?The whole voting in Delhi is a charade. Neither Congree nor BJP is interested in winning Delhi. Without having your own government in Center, winning Delhi means nothing to Congress. BJP is in central government so automatically it rules Delhi. Law and order in Delhi is not a state subject. It is in central government's control. Similarly there are many other state subjects which is not controlled by CM. Hence Arvind Kejriwal can build school and colleges and wifi and every other thing, he does not have the same power in the state as any other CM has in his or her state. Congress knows this. Hence they are not trying hard for Delhi. BJP might loose Delhi but it will still have Delhi. There will hue and cry and people will say BJP lost another state in a trot but will not matter. BJP is gunning for bigger battles. West Bengal is an instance. Winning in West Bengal open doors to full North-East. Winning in Easy gives a strong push to BJP. That is the main target. Delhi is a dummy------3. Who died withholding the biggest secret?All the answers seems to be directed at math , and I can't find you mentioning the word 'only math' in your question . So I thought it might be interesting to put something different . What about princess Diana ? Princess of Wales died in 31 August 1997 . People around the world struggled to know if she were murdered or died in an accident.I guess she ( and the 3 people died with her ) are the only ones who can answer this question right now, although if you researched enough you'll find a whole lot of evidence showing she was murdered and a lot more other showing that it was just another road accident .Adolf Hitler There is some evidence that the nazi leader Adolf Hitler didn't commit suicide as announced but that he had escaped Berlin in the last moments (days maybe ) and lived in Argentina , there are even some books around it people even went further and said that Angela Merkel is his daughter!! ( which I don't personally believe ) But who knows , it's just Adolf who knows if he was dead or alive , maybe his so claimed daughter knows too .------4. Has history ever been changed by an inadvertent bodily function?What a great question! Makes me think, and I found out I dont know any really good answers, though Im sure I must have run across some that I forgot.But, how about something simple like putting others at risk for harm?For example, let us say we can look back on history with a 2020 vision to judge bodily functions during the pandemic war. Some cannot handle the war, and would go nuts having to stay in trenches till its over. They would might refuse night vision goggles so that they wont have to know how many enemy is actually out there.SO, they might not wear masks and cough or sneeze and then others unwittingly pass thru or touch those spaces. Or some might just scream for freedom, jump out of the trenches, running without concern for putting others at risk for harm.History could have alternate routes with something as overt as how people leave their presence in public------5. When i connected 4 LEDs i read 0.5 volt on my voltmeter.I added 4 more LEDs and it reads 1 volt,why is that?Assuming they aren't connected to a power supply, probably the ambient room light is charging them up and your voltmeter is loading them down a little bit, too. LEDs work as light sensors as well as light emitters.If you are trying to use your LEDs as light sensors, that's one thing. (A lot of methods are available there.) If you are trying to use them as a power source, that's going to be a lot more complicated (and mostly impractical except in rare circumstances where you actually know what you are doing and why.)Regardless of any of that, you can't expect to increase both voltage and current without an external power supply. Useful power out is always less than useful power in. You can "optimize" the load point to improve the net power extracted from a solar cell (or, for gosh sake, an LED.) But that's circuit design, not a violation of physical laws.------6. Could you write a one paragraph bio/testimonial about yourself that sounds entirely fictitious/embellished but is actually completely true?Professor Michel Clasquin-Johnson has lectured to a quarter of a million students on the topic of Religion Education and Religious Studies. Students regularly describe him as the best lecturer they ever had. For about ten years he was the entire Buddhological establishment on the continent of Africa. He has published books and articles on these subjects, but also on programming and computer language. In his younger days, he was active in alternative UI design but later turned to the creation of fundamental utilities for various Operating Systems. He has published poetry, non-fiction, and fiction, and is the editor of online magazines with over ten thousand subscribers. He serves on the editorial boards of specialized academic journals and has been Secretary-General and later Vice-president of a learned society. Professor Clasquin-Johnson was awarded the C3 rating by the National Research Foundation, an honour held by less than 0.001 percent of the population. As a professor in the field of Religion, he is entitled to put forward nominations for the Nobel Peace Prize.------7. How would you rank the albums of Led Zeppelin, worst to best?In Throught the Out DoorPresenceIIIIIIHouse of the HolyPhysical GraffitiIVThis is not random: you can see three periods of Led Zeppelin in this ranking.-The last two or three records (Coda would be bottom if you want to include it) are the worst. The worst for Zeppelin is still magnificent and they are both full of gems (cant include Coda there). Achilles puts Presence ahead, but they have a similar vibe.-The first three are Zeppelins blitzkrieg on the 70s. Its the pillars of the band pushed to their maximum : hard rock, blues, folk. To me, the three are similar in quality and the order was hard to make. In the end, III is where they began to put so much work in sound and arrangments.-Then you have magic. IV, House, and Physical Graffiti are the best of Led Zeppelin. The main achievement of Zeppelin was this ability to create new songs and new sound. In three records, they had more diversity than most bands could achieve in their whole career : and always perfect------8. Is India doomed if Modi wins 2019 general election?Yeah.We will be doomedOur PM works hard sleeping 4 hours a day.He is definitely trying to destroy our country.He doesn't make crude remarks and shows utmost respect to his opposition who do not reciprocate.Nor does he concenrate on unwanted politics or gossip.Surely this is bad for our country.He tries to initiate policies that will help collective and wholistic growth rather than just give freebies and use vote bank politics to achieve short term personal gain.How selfish?He makes foreign trips to keep up better foreign relation which will help ultimately.Arrgh.Even I want to go on tours.I could go on about the endless natural disasters happening in our country because of our PM because what else could be the reason.I hope I made myself abunduntly clear.Not asking anyone to vote for the BJP.There are sour grapes in every vineyard.Just realise that our PM is working hard and the least he doesn't deserve are questions like these------9. If you could go back in time, which bands would you watch perform?The Sex Pistols gig at Manchester Free Trade HallTogether with Woodstock (which I'd also loved to have seen) probably the most influential gig ever."We know that Morrissey was there, who went on to form the Smiths. We know that the lads who went on to form the Buzzcocks were there because they organised the gig. We know that two lads from Lower Broughton were there who went out the next day and bought guitars at Mazel Radio which used to be on Piccadilly Station Approach, they formed a band called Joy Division; We know that Mark E Smith was there who went on to form The Fall; we know that Paul Morley was there who went on to become a writer and wrote about the scene for the NME etc.nFamously, about 7000 people claim they were there - but actually attendance was dire and only about 40 people were there !Sex Pistols gig: the truthWoodstockVelvet Underground - perhaps at Max's Kansas City S(since I know the play list & have the record) or perhaps in New York (seem's more appropriate)------10. If police kick down your door in the middle of the night (no warrant) and you think it's an intruder, pull your gun out, and fire on cops (because you're half asleep and think you're getting robbed), is there a legal defense for this?Does this happen to you a lot?First, its unlikely that the police will kick down your door in the middle of the night without a search warrant. Police can make a warrantless forcible entry under exigent (emergency) circumstances, but it would have to be something like the building being on fire or someone screaming for help inside. They would try to get your attention in the conventional way first, and it would be unlikely that you would sleep through it.Second, any cop that would be making entry under these circumstances would be screaming POLICE OFFICER! or something similar very loudly and repeatedly. They would also likely be wearing a uniform or raid jacket that said POLICE in big letters.Third, anytime you shoot at someone without being very sure that they are a legitimate threat is likely to incur criminal liability for you.Is there a criminal defense for this? Sure. Mistaken identity, personal defense, defense of castle, police misconduct, etc. A better question would be Are there any good defenses for this? Probably not.------11. Where did Led Zeppelin record their albums?Led Zeppelin(album)-Olympic studios, LondonLed Zeppelin 2 - This album was also recorded at Olympic studios, London.Led Zeppelin 3-Headley Grange,and at Olympic, with further recording at Island Records' Basing Street Studios in Notting Hill the following month.Untitled/Led Zeppelin 4/ Zoso-Rolling Stones Mobile, Headley Grange, Hampshire Island, LondonHouses of The Holy-Houses of the Holy was mostly recorded using the Rolling Stones' Mobile Recording Studio at a country estate in England. 2. The album's cover art was inspired by the ending of Arthur C. Clarke's book Childhood's End and features a photograph taken in Northern Ireland.Physical Graffiti-Recording. The first attempt by Led Zeppelin to record songs for Physical Graffiti took place in November 1973 at Headley Grange in Hampshire, England, where they had previously recorded their untitled fourth album. The recording equipment consisted of Ronnie Lane's Mobile Studio.Presence-Musicland, Munich, GermanyIn Through The Out Door-In Through the Out Door is the eighth and final studio album by the English rock band Led Zeppelin.

How to make a "Genetic Repo Man" helmet?
That's really awesome! I loved the look of the Repo man, and wanted to make a costume, but such an endeavor is too time consuming and time is something I lack these days. Anyway, I found a suit online for $200 dollars here, http://www.google.com/search?um1&hlen&safeoff&clientsafari&biw1024&bih690&qrepo%20the%20genetic%20opera%20costume&ieUTF-8&tbou&tbmshop&sourceog&saN&tabif&eimGNQT4yzF42ftwe7ocGmDQ It may be a lot for just the helmet but maybe you can tailor the suit to your body. I found tutorials for Pavis mask, but none for the Repo Man. Sorry. Possibly co struct one yourself from a malleable plastic, or leather. It looks like a pretty easy design, just be creative. Cool note, if you like Repo you may know of director Darren Lynn Bousman. Bousman is a graduate of Full Sail University in Florida, which is where I attend film courses. • Other Questions Why is National Media silent on the Raniganj & Kankinara riots in West Bengal? You definitely know the answer.A very prominent reason is to curb the fire from spreading. But this isn't your answer.Let me clear you one thing. There weren't only two places(Raniganj and Kankinara) that fell into the fangs of riots in Ram Navmi. There were more which did similar damage to life and property as these places. A few namely, Purulia , Mednipur, and Burdwan.So this time there was a fight between TMC and VHP,RSS alikes to boast a Ram Navmi procession in different parts of the state . You might have heard of riots in the three places I mentioned later. You say why? The Rally in those places was led by VHP, RSS alikes.And Raniganj and Kankinara? It was led by TMC. So Ms. Mamta played her media wand to abandon media coverage in these two places while allowing full coverage to the above three areas. There's your answer. Sensitive issue? Dayyum. P. s. I live in Kankinara and I'm expecting to post a detailed answer on the riot very soon.Edit : Here's the answer.What exactly happened in the Kankinara Ram Navami celebration? ------ What has made you motivated recently? I have started reading Crushing It By Gary Vaynerchuck.There's this small paragraph which has motivated me immensely to focus on my goals.Will write down the gist of the same here :Work towards your goals twelve , fifteen hours per day. If you're working another job , you should be cramming as much work as you can in the 3 or 4 hours you have to yourself per night ( or day) . Sleep for atleast 68 hours but make every remaining minute count.Be self aware. If you think that working so much is not for you then it's OKAY. Everyone has to live life on their own terms and not force themselves into this life.If one is not willing to put in the grind , then one should not complain when they don't grow as fast as they want. One should learn to accept that their ambitions are humbler than they originally thought and be good with it. He ends by stating The Laws of Thermodynamics :Whatever energy you put into something will manifest itself in equal amounts when it comes out ------ Would it actually have mattered in World War 2 if Germany had advanced 15 more miles and captured Moscow or had the leadership of the Soviet Union long fled the capital by then? This has a bad premise, which is very common, but also deeply flawed. The premise is that as soon as German troops get to Moscow, they take it.Germans got within sight of Moscow. At that point they were exhausted, while Russians launched a counter attack that collapsed the German front and pushed them back hundreds of kilometers. Heinz Guderian got fired because his retreat was particularly disastrous.This means that even if Germans got into the city proper, there was a very low chance of taking it. They failed to take Leningrad. They got into but never secured Stalingrad. Moscow is a bigger and more important city than either of those. It would have been defended as ferociously as those. Being the central communications node of the USSR, reinforcements and supplies would have flown there from the rest of the USSR. So I very much doubt that the Germans could have taken Moscow had they got to it. If anything, its likely the Soviets would have made a pincer maneuver like Operation Uranus in 1941 instead of 1942 and bagged a hundred thousand German prisoners ------ What is your view of the idea that some kind of sentient being could have kicked off the events that led to the Big Bang? So you are asking a atheist who does not believe in any god - I'll repeat that so as to be perfectly clear - atheist do not believe in any god. Right that's settledNow your question becomes - Atheist, what do you think of a god, not the god who created the Universe, no no no not that one, I'm not talking about that one, I'm talking about the one who created the Big Bang. Different one altogether. Then the Big Bang created the Universe not god. Completely different. What's your view on that god? The one who created the Big Bang?I refer you back to the first line of this post words 7 through to 13 and the repeatIf after you have checked that out see if you can spot the flaw in your questionIf you still do not understand I am sorry but there are not enough words of one syllable and no crayon font make it clearerTo directly answer - the view of a god creating the Big Bang is exactly the same as the view of the god creating the Universe - non belief ------ Which was bigger, the Russian Empire or the Soviet Union? History of the Russian Empire is more than three centuries long. Its territory changed diversely during these centuries.The Russian Empire was of its largest ever size (23. 7 mln sq km) during the reign of Nikolay I (and the beginning of reign of his son) in 1850s. However his successors occurred to be real degenerates and losers:his son Alexander II sold Alaska (1/10 of the Empire) to the USAhis grandson Alexander III used to declare thatu201dRussia is for the Russiansu201d and u201cRussia has only two allies - Russian Army and Russian Navyu201d - and very soon such internal & foreign policies really resulted in a loss of all foreign allies and some of the Russiau2019s territories as well.his great-grandson Nikolay II was an insane ruler who destroyed the Empire finally. The same was in case of the Soviet Union - it changed its sizes during 70 years of its history. The Soviet Union was of its largest ever size (22.4 mln sq km) at the end of 1980s.Therefore, in terms of the territory at the best of their times, the Russian Empire was u201cslightlyu201d (for 1. 3 mln sq km) larger than the Soviet Union ------ Why is Brexit bad for the British Pound given the pressure on the Pound since Brexit? Many people have felt that sterling has been overvalued for a long time, and that devaluation is desirable. There is some basis for this in that exports are cheaper, and if imports are more expensive, then it creates an incentive for people to buy more British goods, which theoretically strengthens the economy and stimulates growth.The big problem is business confidence though. If investors arent confident in our economy, they dont invest.In terms of Brexit, a low pound may actually help negotiations for a trade deal because foreign imports will be more expensive and the volume of foreign trade to the UK is likely to decrease.There is a lot of barely concealed volatility in the EU at the moment, so its more difficult than ever to make predictions. Deutschebank is in trouble, the PIGS economies are still in trouble, France is in massive debt, there are general elections due in France and Germany next year and the (generally more Eurosceptic) far right is worryingly popular, and some of the Eastern European countries are trying to negotiate immigration controls to undermine the basic principle of free movement of people.Who knows - its a bit of a lottery ------ Does every MBBS doctor do PG? A person with a MBBS degree has a working knowledge of all specialties somewhat like Jack of all trades. After MBBS there is a year long internship where the graduate rotates to all departments and gains clinical experience in managing patients under supervision of specialists and minor operations like abscess drainage, stitching wounds as well as assist in surgical procedures, deliveries, tubal ligation and caesarean sections. This adequately equips and prepares them to deal with many clinical situation except the complex cases which they are expected to recognise and refer to appropriate speciality service. After internship many MBBS doctors do residency postings or apprenticeship under senior physicians or even in specialty departments to increase their experience before starting their independent practice.Therefore no MBBS doctor needs a specialty to survive and many MBBS doctors have flourishing practices where patients turn to them for even complex problems that should be handled by specialists . Ultimately it is not a degree but how well you care for your patients that would satisfy you professionally and economically. A caveat though is that one should always work with awareness of one's limitations and that applies even to specialists ------ What are some beautiful, haunting, chilling, soul-wrenching songs (like Young and Beautiful by Lana Del Rey)? Spoiler Alert - The songs I have chosen to share here can be described as melancholy to downright depressing. Soul Wrenching has got to be one of my absolute favorite genres. Glad to chime in with a few that come to mind. Hope you Enjoy! Alice in Chains - NutshellPearl Jam - Pendulum"Pendulum"Can't know what's high 'Til you've been down so low The future's bright, Lit up with nowhere to go, To and fro the pendulum throwsWe are here and then we go My shadow left me long agoUnderstand what we don't know This might pass This might last This may grow Easy come and easy go Easy left me a long time agoI'm in the fire but I'm still cold Nothing works works for me anymoreAh ah ah ah ah To and fro the pendulum throws To and fro the pendulum throwsOleander- HaloThis one never fails to get me reaching for the tissues Tracy Chapman - Bang Bang BangPuscifer - The Humbling River I would describe this song as Hauntingly Beautiful with a bit less melancholy than the songs listed above, perhaps even with a little taste of hope. ------ Was there ever a better person than Donald Trump? There was indeed. I submit my paternal grandmother as a better person than Donald Trump, not to mention a better person than most of the people who have ever lived or are ever likely to.

Common led solar light Questions
1. Would it actually have mattered in World War 2 if Germany had advanced 15 more miles and captured Moscow or had the leadership of the Soviet Union long fled the capital by then? This has a bad premise, which is very common, but also deeply flawed. The premise is that as soon as German troops get to Moscow, they take it.Germans got within sight of Moscow. At that point they were exhausted, while Russians launched a counter attack that collapsed the German front and pushed them back hundreds of kilometers. Heinz Guderian got fired because his retreat was particularly disastrous.This means that even if Germans got into the city proper, there was a very low chance of taking it. They failed to take Leningrad. They got into but never secured Stalingrad. Moscow is a bigger and more important city than either of those. It would have been defended as ferociously as those. Being the central communications node of the USSR, reinforcements and supplies would have flown there from the rest of the USSR. So I very much doubt that the Germans could have taken Moscow had they got to it. If anything, its likely the Soviets would have made a pincer maneuver like Operation Uranus in 1941 instead of 1942 and bagged a hundred thousand German prisoners ------ 2. Was there ever a better person than Donald Trump? There was indeed. I submit my paternal grandmother as a better person than Donald Trump, not to mention a better person than most of the people who have ever lived or are ever likely to. She was unfailingly kind, a brilliant cook, fearsomely intelligent (never shook her strong Greek accent, but was nonetheless conversant and literate in five languages Greek, Romanian, Bulgarian, Spanish and English), played a wicked game of 21, was more loving and loyal to my mom than her own mother was, loved to laugh, had a sly subtle wit, smelled good, and had soft hands and a handshake that always warmed and welcomed, never challenged. If it hadnt been for the whole not-a-natural-born-citizen thing, she would have made a fine President, too. Im not sure why you asked, but I am very glad to have had the opportunity to tell you about my beloved YiaYia, who was unquestionably a better person than Donald Trump. Should this answer not meet your standards, I will be happy to provide you with the names and brief biographies of any number of other fine folk of my acquaintance who have ever been a better person than Donald Trump ------ 3. How to make a "Genetic Repo Man" helmet? That's really awesome! I loved the look of the Repo man, and wanted to make a costume, but such an endeavor is too time consuming and time is something I lack these days. Anyway, I found a suit online for $200 dollars here, http://www.google.com/search?um1&hlen&safeoff&clientsafari&biw1024&bih690&qrepo%20the%20genetic%20opera%20costume&ieUTF-8&tbou&tbmshop&sourceog&saN&tabif&eimGNQT4yzF42ftwe7ocGmDQ It may be a lot for just the helmet but maybe you can tailor the suit to your body. I found tutorials for Pavis mask, but none for the Repo Man. Sorry. Possibly co struct one yourself from a malleable plastic, or leather. It looks like a pretty easy design, just be creative. Cool note, if you like Repo you may know of director Darren Lynn Bousman. Bousman is a graduate of Full Sail University in Florida, which is where I attend film courses. ------ 4. Why is Brexit bad for the British Pound given the pressure on the Pound since Brexit? Many people have felt that sterling has been overvalued for a long time, and that devaluation is desirable. There is some basis for this in that exports are cheaper, and if imports are more expensive, then it creates an incentive for people to buy more British goods, which theoretically strengthens the economy and stimulates growth.The big problem is business confidence though. If investors arent confident in our economy, they dont invest.In terms of Brexit, a low pound may actually help negotiations for a trade deal because foreign imports will be more expensive and the volume of foreign trade to the UK is likely to decrease.There is a lot of barely concealed volatility in the EU at the moment, so its more difficult than ever to make predictions. Deutschebank is in trouble, the PIGS economies are still in trouble, France is in massive debt, there are general elections due in France and Germany next year and the (generally more Eurosceptic) far right is worryingly popular, and some of the Eastern European countries are trying to negotiate immigration controls to undermine the basic principle of free movement of people.Who knows - its a bit of a lottery ------ 5. Does every MBBS doctor do PG? A person with a MBBS degree has a working knowledge of all specialties somewhat like Jack of all trades. After MBBS there is a year long internship where the graduate rotates to all departments and gains clinical experience in managing patients under supervision of specialists and minor operations like abscess drainage, stitching wounds as well as assist in surgical procedures, deliveries, tubal ligation and caesarean sections. This adequately equips and prepares them to deal with many clinical situation except the complex cases which they are expected to recognise and refer to appropriate speciality service. After internship many MBBS doctors do residency postings or apprenticeship under senior physicians or even in specialty departments to increase their experience before starting their independent practice.Therefore no MBBS doctor needs a specialty to survive and many MBBS doctors have flourishing practices where patients turn to them for even complex problems that should be handled by specialists . Ultimately it is not a degree but how well you care for your patients that would satisfy you professionally and economically. A caveat though is that one should always work with awareness of one's limitations and that applies even to specialists ------ 6. What are some beautiful, haunting, chilling, soul-wrenching songs (like Young and Beautiful by Lana Del Rey)? Spoiler Alert - The songs I have chosen to share here can be described as melancholy to downright depressing. Soul Wrenching has got to be one of my absolute favorite genres. Glad to chime in with a few that come to mind. Hope you Enjoy! Alice in Chains - NutshellPearl Jam - Pendulum"Pendulum"Can't know what's high 'Til you've been down so low The future's bright, Lit up with nowhere to go, To and fro the pendulum throwsWe are here and then we go My shadow left me long agoUnderstand what we don't know This might pass This might last This may grow Easy come and easy go Easy left me a long time agoI'm in the fire but I'm still cold Nothing works works for me anymoreAh ah ah ah ah To and fro the pendulum throws To and fro the pendulum throwsOleander- HaloThis one never fails to get me reaching for the tissues Tracy Chapman - Bang Bang BangPuscifer - The Humbling River I would describe this song as Hauntingly Beautiful with a bit less melancholy than the songs listed above, perhaps even with a little taste of hope. ------ 7. Why is National Media silent on the Raniganj & Kankinara riots in West Bengal? You definitely know the answer.A very prominent reason is to curb the fire from spreading. But this isn't your answer.Let me clear you one thing. There weren't only two places(Raniganj and Kankinara) that fell into the fangs of riots in Ram Navmi. There were more which did similar damage to life and property as these places. A few namely, Purulia , Mednipur, and Burdwan.So this time there was a fight between TMC and VHP,RSS alikes to boast a Ram Navmi procession in different parts of the state . You might have heard of riots in the three places I mentioned later. You say why? The Rally in those places was led by VHP, RSS alikes.And Raniganj and Kankinara? It was led by TMC. So Ms. Mamta played her media wand to abandon media coverage in these two places while allowing full coverage to the above three areas. There's your answer. Sensitive issue? Dayyum. P. s. I live in Kankinara and I'm expecting to post a detailed answer on the riot very soon.Edit : Here's the answer.What exactly happened in the Kankinara Ram Navami celebration? ------ 8. What is your view of the idea that some kind of sentient being could have kicked off the events that led to the Big Bang? So you are asking a atheist who does not believe in any god - I'll repeat that so as to be perfectly clear - atheist do not believe in any god. Right that's settledNow your question becomes - Atheist, what do you think of a god, not the god who created the Universe, no no no not that one, I'm not talking about that one, I'm talking about the one who created the Big Bang. Different one altogether. Then the Big Bang created the Universe not god. Completely different. What's your view on that god? The one who created the Big Bang?I refer you back to the first line of this post words 7 through to 13 and the repeatIf after you have checked that out see if you can spot the flaw in your questionIf you still do not understand I am sorry but there are not enough words of one syllable and no crayon font make it clearerTo directly answer - the view of a god creating the Big Bang is exactly the same as the view of the god creating the Universe - non belief ------ 9. Which was bigger, the Russian Empire or the Soviet Union? History of the Russian Empire is more than three centuries long. Its territory changed diversely during these centuries.The Russian Empire was of its largest ever size (23. 7 mln sq km) during the reign of Nikolay I (and the beginning of reign of his son) in 1850s. However his successors occurred to be real degenerates and losers:his son Alexander II sold Alaska (1/10 of the Empire) to the USAhis grandson Alexander III used to declare thatu201dRussia is for the Russiansu201d and u201cRussia has only two allies - Russian Army and Russian Navyu201d - and very soon such internal & foreign policies really resulted in a loss of all foreign allies and some of the Russiau2019s territories as well.his great-grandson Nikolay II was an insane ruler who destroyed the Empire finally. The same was in case of the Soviet Union - it changed its sizes during 70 years of its history. The Soviet Union was of its largest ever size (22.4 mln sq km) at the end of 1980s.Therefore, in terms of the territory at the best of their times, the Russian Empire was u201cslightlyu201d (for 1. 3 mln sq km) larger than the Soviet Union ------ 10. What has made you motivated recently? I have started reading Crushing It By Gary Vaynerchuck.There's this small paragraph which has motivated me immensely to focus on my goals.Will write down the gist of the same here :Work towards your goals twelve , fifteen hours per day. If you're working another job , you should be cramming as much work as you can in the 3 or 4 hours you have to yourself per night ( or day) . Sleep for atleast 68 hours but make every remaining minute count.Be self aware. If you think that working so much is not for you then it's OKAY. Everyone has to live life on their own terms and not force themselves into this life.If one is not willing to put in the grind , then one should not complain when they don't grow as fast as they want. One should learn to accept that their ambitions are humbler than they originally thought and be good with it. He ends by stating The Laws of Thermodynamics :Whatever energy you put into something will manifest itself in equal amounts when it comes out
Could billions of little micro solar power plants feed the whole world via our phone lines?
Not an expert, comments only: - a washing machine, vacuum cleaner, . needs roughly one kW. An A/C unit/ heat pump 3-5kW. An average US household (not yours) consumes 12kWh a day. i.e. an average of 500W. All this way above phone line capability. Also phone lines will go away (replaced by fiber optic). Note, the existing "fiber internet" in NJ at this time is only a few % (2- 5%) utilized. Ie. massive fiber laying has created capacity for at least 1.5 decades. What is really needed are fibers into your home. Expect opposition from existing coaxial copper (CATV companies). In short, nothing doing. - the distribution network for your proposal will be a MAJOR problem. Windmills have already been studied extensively. Result, anything above 15% windmills --of the total electricity consumption in a country-- requires massive investments in "battery storage", "substations", new and denser networks of the medium voltage power lines. For the records, even Denmark will stay for the foreseeable future at their present 17% windmill power (I think that is their number). - a much better solution MAY in fact be a diesel-turbine in everybody's basement: 1. it creates heat (65% of combustion power is "heat"), 2. can drive the heat pump also for A/C and heat (with an efficiency twice that of a gas furnace), 3. light your home. Even that solution is NOT the utilities' who have invested massively in 1Mio V long distance DC transmission lines and Giga Watt power stations favorite brain child. They will fight this idea 'toe and nail' (PS: Reason, every time you run the generator, they would have to buy your "excess basement electricity" at a large premium, e.g., using the all too successful Danish windmill scheme, at 70% of their retail pricing). - very similarly, you could install a 10kW fuel cell in your basement. It would run (if high temp ceramic) not on hydrogen, but ethanol. I do not want to get carried away, how, when, how much, But, the efficiency of that would be twice as high as the diesel turbine/ engine (60%). Also, with ethanol you keep the distribution network (tanker trucks). And no need to remind you, such fuel cell can be installed in cars. Again, I must refrain from singing my song too loudly. - SOLAR: at this time the energy needed to produce a solar cell is close to what it delivers over its life time. Apart from the economy of solar power operation and the complexity of the network, it is not yet a good idea to mass produce solar cells. • Other Questions How do professional programmers measure how "fast" their code runs?

The answers already given are all quite good. However, there's another aspect of "poor leadership" that hasn't yet been addressed, and that's the extent to which the French senior levels of command kept their decision-making centralized.The reality of the German invasion in May 1940 was that it happened very quickly, and evolved very quickly. The Germans had, thanks to the way they'd trained their leaders prior to the war, decentralized decision-making to the extent that low-level leaders could make really significant decisions. This put decision-making very close to the parts of the battle whose course hinged on those decisions. The French, on the other hand, had maintained a much more rigorous, centralized and "scientific" approach to their command and control. As a result, decision-making authority was centralized at higher levels of command. What happened as a result was that both the French and the Germans would observe an evolving situation on the battlefield. A German commander on the spot could make and implement a decision about it. His French counterpart, however, could only report what was going on to a higher HQ, and would then have to wait for that HQ to make a decision and report it back for implementation. By the time that happened, however, the situation had changed, so the decision received by the local French commander from higher was now obsolete. The Germans, in the meantime, had continued to make decisions effectively on the spot, so were now one or more decision cycles ahead of the French. This is a classic example of one opponent getting "inside" the decision cycle (also called the OODA--observe, orient, decide, act--Loop, or Boyd Cycle, after a U.S. Air Force officer who was an early thinker about this stuff) of the other. The slower decision-maker's decisions become increasingly out-of-date and irrelevant, until eventually, his chain of command has lost situational awareness and control of the battle. The fact that the French had both quantitative and qualitative superiority in terms of their forces was rendered essentially irrelevant by it not being in the right place at the right time, to do the right things to affect the course of the battle.Modern military forces, particularly in the West, have taken lessons like this one to heart. Decision-making is now not only authorized at low levels, it's encouraged. Risks are accepted; mistakes are expected and treated as opportunities to learn (during training, anyway!) All soldiers are told the plan, at least in a general sense, and everyone understands their commander's intent--that is, the major things he wants to accomplish. HOW they get accomplished is of less concern to senior leaders, leaving a great deal of scope for lower-level, individual initiative and innovation

Can a solar fencer be used to power LED string lights?
LED bulbs additionally comprise various brightnesss. long gone are the days once you could evaluate the wattages of bulbs to tell apart, which bulb would be brighter rather now you may desire to think of Lumens. the reason at the back of it rather is that a 50w halogen GU10 spotlight can get replaced with an equivalent 5w LED GU10 spotlight the decrease wattage is the main reason families can gain such great power value reductions from LED bulbs you only might desire to verify that the lumens are comparable between the two varieties of bulb to confirm you will get the comparable style of sunshine intensity. • Suggested Reading Why didnu2019t the Soviet Union interfere in the Falklands war? In what way? If you mean militarily, then that would bring the Americans into the game. Not only would the USA not stand by when a major ally was attacked, but they would absolutely not countenance the USSR being involved militarily in South America. As it is the USA barely tolerated the Soviet support for Cuba and at the time of the Cuban missile crisis they imposed a blockade. Also, the Argentinians were not Soviet allies and were actually rather closer to the USA. Politically Argentina was at the opposite end of the scale to the the USSR. As it is, the USSR abstained on United Nations Security Council Resolution 502 an decided to keep their distance from proceedings. ------ What exactly is at stake if Donald Trump gets to replace Justice Ruth Bader Ginsburg? Whats at stake is every piece of liberal legislation passed by any future administrations for the next 30 or 40 years. Along with all liberal legislation and SCOTUS decisions that exist now.What we have currently is a right wing majority including a swing justice whos concern for the legitimacy of the court has led to him stepping in and voting with the moderate minority of a number of issues, such as the ACA. Ginsburg goes and Trump and Moscow Mitch will replace her with a young hard liner who doesnt care in the slightest about the courts legitimacy.Vote in November. Vote as if America depends on it ------ How does Facebook plan on recouping their $19 billion investment in WhatsApp, now that WhatsApp has encrypted their messaging service? I've read the encryption is more like WhatsApp > Facebook servers > encryption > WhatsApp. Don't know how true that is though because that would almost defeat the point of encryption. I suppose they could use an https protocol to their server to prevent man in the middle attacks which would work well. Then they could encrypt using public/private keys using their servers compute power instead of your phone, and then send it back using HTTPS again, not that it would matter as much on the return trip. Seems like this might be the way they do it, meaning their servers can still do all the data mining they want on your messages before they're encrypted ------ What did President Trump mean when he tweeted that u201cpolice must take a stronger stand with the radical left politicians?u201d I havent heard that one but if he did say that, its a serious problem for all of us. Just reading * Police must take a stronger stand with the radical left politicians* coming from the president sounds too much like a police state to me. Am I wrong? Whats next? It really worries me that this type of thinkinking is just a step away from dictatorship. Its past time for all of us to just set back and wait for others to take action. We need to support the opposition to this megalomaniac. The best we can do now is donate, if and however much you can, to the campaigns of those in the fight to replace the enablers of this travistry of leadership. Keep Safe, Stay Healthy, Be Strong and Happy. ------ What is the difference between a Leftist and a Liberal? In the United States, today, none.In reality, left wing should refer to communists, Marxists, Nazis, fascists - all the various components of socialism.In reality, liberal should refer to a person who is willing to consider any and all positions, and argue for or against - with logic and facts a position. A liberal should be willing to say You have a right to be wrong, just dont force me to accept your views. A true liberal would be 100% for Voltaires I disagree with you but will defend unto death your right to say it stance. (a modern liberal will attack you for even daring to espouse a position in opposition to them) ------ Are there valid Economic Reasons for Brexit? One of the biggest untruths told during the referendum campaign, and promulgated by the supposedly neutral BBC, was that the economic case for Remain had been proven. In reality the EU has been an economic disaster, its bureaucracy stifling innovation and its trade rules explicitly opposed to free trade and prosperity. The track record of the EU is dismal. It's been in terminal decline for decades. Corrupt, ossified and half a century out of date; why anyone would want to stay in a club which let Greece in is beyond me.Michael Price's answer to How would you explain the reasons for Brexit to someone?The reasons are spelt out in more detail here; long, but well worth watching: ------ Why is algebraic geometry so abstract compared to most other areas of mathematics? If youd like to understand algebraic geometry from a more concrete point of view, Shreeram Abhyankar wrote a book entitled, Algebraic Geometry for Scientists and Engineers.Abhyankar divided algebra into three regimes: High School Math, College Math and University Math. He was not denigrating simple math, he was a big fan of understanding algebraic geometry in terms of high school math. He felt there was quite a lot that could be understood via high school math and that rings and categories could distract from the very accessible beauty of algebraic geometry.Heres an essay with his views: https://www.ime.usp.br/pleite/pub/artigos/abhyankar/abhyankar. pdf. ------ Why did Canadians have such a ruthless reputation in WW1? Because Canadians got the job done, where no one else could. The Canadians were used as shock troops, so much so that it became paramount to NOT let the Germans know that the Canadians were coming into the line, because it indicated an attack in that sector.Both the French and the British tried taking Vimy Ridge and failed with massive casualties. The Canadians took it in two daysEven when attacked with gas the Canadians held their section of line while the French units on their flank fled.At Amiens the British moved the Canadians up to the line utmost secrecy and the attack was the start of a 100 days of victory, a black day for the German Army which ended only when the Germans agreed to an armistice ------ Why does the stock market go up when unemployment increases and wages go down? Because the stock market acts ahead of the real economy, typically about 18 months ahead. For example, the stock market began to fall in October 2007, while unemployment shot up and wages declined in early 2009, at which time the stock market had seen the bottom and was rebounding back up, predicting the employment and wage gains that would begin late in 2010.The stock market, employment and wages are all strongly correlated to real activity. In good times businesses make profits, people are hired and pay goes up; in bad times the reverse is true. But the correlation is not simultaneous. The stock market is a prediction of future profits, employment and wages react to past losses ------ Why is Japan's birth rate so low? Birth rate has decreased in every society where education has taken predominance.And independence of women is a norm.Japan has other reasons too.To-date Japan has gender baise. Men's and women's world are segragated. They do have coeducation, but you will rarely see mixed group.Women don't get to meet men. Except in their work places.Parents are more dependent on their daughters than sons, a reason why women can't leave their homes. Women living with their parents, have more money to enjoy, they don't want the responsibility of husband and children.This is a very complex problem. Will be very difficult to solve for the Japanese government ------ How much would you rate your beauty, on a scale of 1-10? Remember this: I think Im a bit insecure, so thats thatfaceeyes: black, round, largenose: smallskin: acne yayyyyyyeyebrows: faintlips: a bit towards the thick sideface shape: round, but somehow slimmaybe a 4.5/10?bodyheight: short thats all im going to sayarms: skinny wrists, but towards the shoulder part not so much im unproportionedlegs: NOT skinny2/10?hairlong hairblack, or as some people say, dark dark dark brownreally evenmy hair is REALLY straight, I have never straightened my hair - but if I go to sleep with my hair half wet it will still be straight, and i do sleep on my hairmy hair gets tangly pretty fastTHICK AND A LOTsometimes its soft, sometimes its not8/10?styleoversized hoodiesblackmore blackblack leggings or sweatpantsblack shirtsBLACK.i dont care about this ratingso overall maybe a 5/10?. ------ If police kick down your door in the middle of the night (no warrant) and you think itu2019s an intruder, pull your gun out, and fire on cops (because youu2019re half asleep and think youu2019re getting robbed), is there a legal defense for this? If police kick down your door in the middle of the night (no warrant) and you think its an intruder, If you pull your gun out and fire on cops (because youre half asleep and think youre getting robbed) Is there a legal defense for this?On March 13, 2020, Breonna Taylor was SLEEPING when police busted down her down and entered into her home using a no-knock warrant.The killers, (who were officers for the Louisville Metro Police Department) Jonathan Mattingly, Brett Hankison, and Myles Cosgrove fired TWENTY SHOTS. SHE WAS SLEEPING. SLEEPING.So to answer the question, according to the CONSTITUTION, you can own a gun. Legally, you can shoot people who are on your property. However, when those people on your property are police, your rights are completely stripped away in reality ------ Why did the President of China visit a small nation like Nepal in 2019? What may be the main motives? Why not ?Despite the warming of relationships with arch foe India, the dictate of my enemys friend becoming my enemys lesser friend is always preferred.India had always a close and dominating relationship - now run by a communist government - and warming the relationship with Nepal through massive cheque book diplomacy not only rubs excrement in Indias face, any real alliances - being trade or military always is to Chinas benefit.In the end, imho, the biggest winner is Nepal - since the impoverished nation can play off the two enemies against each other for financial aids. But in the end / when push comes to shove, India will prevail - blood is thicker than water due to the immediacy in race between Indians and Nepalis ------ What is the meaning of life according to religious and nonreligious views? This is a non-question. Its like asking what is the meaning of a mountain, or what is the meaning of the sky, or what is the meaning of toothpaste.Life has no meaning; people are just alive, its as simple as that.And this is actually comforting. It means you are free to put whatever values you want into your life and live a better life than if you thought your meaning was something fixed. If there was a meaning to life then nothing would have value. It would be like reading the last part of a suspense thriller where you get the answer before you read the rest of the book. It would also mean that everything is already set, and you have no actual choice in anything. ------ What prompted the Israelis to wage the 1967 war? To seize Eretz Israel, i.e., East Jerusalem and land up to the Jordan River, the West Bank. This had been the plan in 194748, but Jordan, realizing Ben Gurion had deceived the Kingdom as to his true intentions, intervened and stopped the Hagganah cold. Thereafter Israel bided its time, and after JFK was dead (JFK had warned Ben Gurion and Ekol that he would not support an Israeli invasion of East Jerusalem and the West Bank), and Christadelphian cult member LBJ was President (the Christadelphians WORSHIP Israel see, Centrality of Israel), the road was open for the surprise attack launched by the Israeli air force in 1967 against its neighbors (see, How Christadelphian love of Israel impacted the outcome of Israels Six Day War.

LED bulbs additionally comprise various brightnesss. long gone are the days once you could evaluate the wattages of bulbs to tell apart, which bulb would be brighter rather now you may desire to think of Lumens. the reason at the back of it rather is that a 50w halogen GU10 spotlight can get replaced with an equivalent 5w LED GU10 spotlight the decrease wattage is the main reason families can gain such great power value reductions from LED bulbs you only might desire to verify that the lumens are comparable between the two varieties of bulb to confirm you will get the comparable style of sunshine intensity. ------ 12.
