Try the following, if you have not read them already:
1. Guns, Germs and Steel by Jared Diamond- not only generally rated as the top science book but also the top history book of recent time, read it and you will find out why.
2. Godel, Escher, Bach by Douglas Hofstader - a bit older but rated #2 science book by the general populace in my research. Great stuff about AI and recursion.
3. Genome by Matt Ridley - an excellent work, each chapter is about a discrete human chromosome and tells you what it does, fascinating.
4, The Structure of Scientific Revolutions by Thomas Kuhn - essential to understanding how it happens.
As a big fish in a small pond academic librarian, I generally spend around $20k a year on books which I select myself, so I devote a lot of time to reading reviews. Those four I mentioned are absolutely necessary reading according to my sources.
Read not to contradict and confute, not to believe and take for granted, not to find talk and discourse, but to weigh and consider. - Francis Bacon
