(Atlantic Ocean)------Is the speed of light in all media independent of reference frame?The speed of light only differs when comparing it in two mediums with a different refraction index. With the added changes we can say that the detector with $vv$ will detect the light as going $-v$ slower than $c$ and vice versa------Plotting the Cornu spiralThanks to @Adriaan for 3 bytes off!Here's an example with input 365 366... because today is MATL's first birthday!

There's a whole load more in xscreensaver-data-extra too if you want something different------Is $mathbbZ/3mathbbZ times mathbbZ/3mathbbZhspace0.5mm$ isomorphic to $hspace0.5mmmathbbZ/9mathbbZ$? duplicateNo. You can see this by considering the orders of elements: As a cyclic group, $mathbbZ/9mathbbZ$ has an element of order $9$ (for instance its generator). But, $mathbbZ/3mathbbZ times mathbbZ/3mathbbZ$ only has elements of order $3$------Magento EE FPC ignored when in https?I think you are correct with your interpretation, If the request ends as https at magento, FPC will do nothing.But if you end https before, e.g. In the load balancer, the request will hit magento as http, therefore FPC will work------light sensor brick - what is n pin? closedIf it is like this one, the pinout looks like this: And the schematic looks like this: So the "N" connection on the "Grove" connector is just an "NC" (not connected).

It's true that the surface isn't perfectly smooth, but it's very close. The roughness might be up to 10 nm or so, but visible light is 550 nm, so it in effect doesn't really see the surface roughness------Finding maximum likelihood estimator of $theta$The likelyhood, as you calculated it is$L(theta) propto frac1theta^nmathbb1_theta geq max |fracx_i-ii|$It is self evident that $L$ is strictly decreasing in $theta$ so$hatthetamax|fracx_i-ii|$is your MLE------How to remove a stuck bayonet-mounted light bulb?I would disassemble the fixture so you can get to the socket and bulb itself.

Go with a quality LED and you'll never have to replace it again.------Is it possible that the universe is not expanding faster than the speed of light? closedWell that depends as researchers say that the the universes expansion is accelerating because of dark energy that increases spaces at various points, it is hard to determine what the acceleration rate is but it is noted in 1998 by researchers of the acceleration------check engine light 2006 kia sedonaTake it to a workshop and have it fixed.

The pedal is now pushing the button back in so it's working again! ;-)------Why is the Sun made of light elements only?The Sun didnt select out heavy elements from the cloud. The planets selected out light elements because they dont have enough gravity to hold on to their hydrogen and helium.Source:------A question about cardinalityIf $A$ avoids an open interval $(a,b)$, then it is not dense. The only non-dense subgroups of $Bbb R$ are of the form $aBbb Z$ (possibly $a0$). So $Bbb R/A$ is homeomorphic to $S^1$ (or $Bbb R$ itself) und uncountable.------How to transfer data from Lightning page to VF pageHere is the code i used for sending data from lightning to vf page , i hope this will help you Here is my lightning code Lightning controller - Here is the vf page - If you need any more help, let me know------Approximately how much does a catcher's gear weigh?Eh, about 5 pounds. Maybe 10 if you have a heavy set of shinguards and one of the hockey-style masks. You could just look it up on some sporting good websites.

This is normal behaviour. However, flashing lights are not------redshifted or scaled light?I think that's correct, although this is arguably a terminology rather than a physics question: certainly frequency (and similarly wavelength) is multiplied by a factor, and doesn't have some constant added to it.Also, see Sean Lake's answer which gives a beautiful explanation------Speed of light definition closedIn 1980-something, the standard meter was defined (empasis on defined) as 1/299792458 of the distance light travels in a second. Since the definition of a meter is that exact fraction, when you measue the speed of light in meters, you get an exact number------A building with three floors and three lights duplicateYou Turn one light on let it heat up, switch it off and turn another light on. You now have 1 light that is hot, one that is on and one that is off and cold and you know what switches they correspond to------What is the grammatical reason for at the end of short responses such as , and ? has different meanings, but in your examples, all three are auxiliary words.
