2.2 Band Gap I - Electrons in an atom

[@tobuslieven]

These lectures are so good!

[@red-baitingswine8816]

As an older college dropout, who remains curious about these things, I find these videos illuminating. They are somewhat deep/comprehensive/accurate without getting too involved in tedious complexities. However I suspect that a reasonable understanding of this stuff might require quite a bit of study for someone with no background at all or without some good high school science and math.

I'm gonna tell my professor.

[@ItsaStringThing]

I love this guy.

Proton not Positron!

[@jacobvandijk6525]

Since when are protons called positrons?????

[@anonxnor]

Red for negative charge?

[@manahilkadhim9934]

Thank you!

[@same.smalls5531]

You keep saying that word... positron... I do not think it means what you think it means.

[@irmaksaglam3782]

I think it is better if you change the name of the video since it is not about band gaps yet, it has confused me.

very well explained thanks ! (I did not study those things, I'm trying to understand why UVC are blocked by glass or plastic, and this answer: physics.stackexchange.com/a/444713/79303 . So it seems I need first to understand what a band gap is!)
