“A Princeton University-led team of scientists has shown how electrons moving in certain solids can behave as though they are a thousand times more massive than free electrons, yet at the same time act as speedy superconductors.”
“Cool the electrons to far below room temperature in certain types of solid materials, and these flighty particles gain mass, acting like much heavier particles. Surprisingly, further cooling close to absolute zero makes these solids become superconducting, where the electrons, despite their heaviness, make a kind of perfect fluid that can flow without wasting any electrical power.”
WOW. What a surprise. Ya learn something new here everyday on FR, I tell ya.
I'm not a physicist.
Energy and mass have a pretty direct relationship, right? E=mc2?
If you cool the electrons, you are taking energy out of the system, right?
So how can the mass (which is basically energy) increase when you take energy out of the system?
