A few years ago I remember browsing a pair of books that had a list of challenge-like questions about everyday physics, such as why do we deep fry hamburgers, how air conditioning works, etc. They came in two volumes, one for classical physics and one for modern. I think the title went something like "100 Everyday Physics Challenges" or similar.
I've been meaning to take another look at those books for a while, but no matter what term I search, I can't seem to find them. Does it ring a bell to anyone?
