No antennae radiate all the power fed to them!

It takes the same amount of heat to raise a substance 1 degree at 77 °K as it does at room temperature. Ok, but when I read (or hear on BBC radio science programs) that it takes FAR more effort (energy) to pump from 2K to 1K than it does from 300K to 299K, what am I supposed to make of that given what you just said? |
