Re: white

A good explanation of the oil-paper deal!

But I'm confused about this hogwash thing.

a real practical insulator is totally different from the hogwash
explanation (large-gap semiconductor) given in almost all
solid-state physics books. A large-gap semiconductor should be
called merely a semi-non-conductor, since it cannot be used as a
practical insulator. It will not immobilize any charge injected onto
or into it.

Isn't diamond a large-gap semiconductor and also a pretty good
(practical except for expense) insulator at 'normal' temperatures????

What is the reason clouds are white?

A fascinating question. Deep physics.
Figured out only relatively recently.
