Then, to put a coda to the whole issue ""It is remarkable to watch electrons moving in a crystal evolve into more massive particles as we cool them down," said Ali Yazdani, a professor of physics at Princeton and head of the team that conducted the study."
EVOLVE INTO MORE MASSIVE PARTICLES?
This guy is the head of the team and he says INTO MORE MASSIVE PARTICLES
He didn't say they were pretending to be more massive, but that they were, in fact, more massive!
This has to do do with quantum physics and the behavior of electrons in a crystal lattice.
Bet you thought it was about breaded chicken bits in a bed of lettuce.
Bite me, idiot.
Study up on what "effective mass" means in solid state physics.
Caution Mass is condensed matter physics is different from mass as it appears in other physics.
