Ebook: Understanding Physics, 3 Volumes in One: Motion, Sound & Heat; Light, Magnetism & Electricity; The Electron, Proton & Neutron (v. 1-3)

This book was written in the 1960s but is surprisingly up to date. As I was remarking to my nephew, we still don't know where all the anti-matter is.

I'm giving less than five stars because this edition had several pages out of sequence, which makes for an unnecessarily confusing reading experience, to say the least. Sad that what is arguably Asimov's non-fiction science magnum opus should be preserved in this fashion.
