At this point, I'm fully in any time AlphaPhoenix releases a video. He explains material science beautifully.
In today's video he explains the differences between crystalline and amorphous (2:30), shows crystalline aluminum under an SEM (3:45), shows how 2-d magnetic discs when agitated spontaneously produce order (5:00-10:30 - the real money portion of the video), and uses a computer simulation to extend this into the third dimension (11:45).
This is a wonderful exploration of how crystals grow - whether they're our copper (II) sulfate crystals in class or cooling aluminum crystals or any other crystals.
Wonderful stuff, man.
