They experimentally demonstrated that it takes significantly more energy to move a microparticle the same distance when cooled than the amount of energy it would take when heated.

- kamray23 3y agoHow can that be possible, though?
- AYBABTME 3y agoIf something is already bumping around randomly, all you need to do is constrain the bumping along some dimensions and it will move less randomly and more frequently toward the remaining free dimensions. That's easier than having to provide all the energy to do the movement directly.
- quux 3y agoConstrained energy basically acts as mass right? So would an intuitive way to think of this be that the warm particle has more energy, but moving it confines where that energy can be so it behaves as if it has more mass?
