The experiment exploits the fact that for holes traveling in a given direction, particles at the Fermi energy have different momenta, associated wi ...

... According to Pythagoras, the basis of the world is number. But how the numbers appear? Really some energy or action (the fire, Pyr, in terms of Heraclitus) (which could be quantified, i.e. numberized itself) has to be applied to introduce numbers into real world. I.e. a number is needed to introduce ...
