Journey Through Genius

I am reading Journey Through Genius which you can find here along with some great reviews. I had been searching for a history of science book since high school. In this book I found exactly what I had been seeking: a book that explained the actual concepts as well as placing them within historical and biographical context. This book however is not about science but math, though actually it is better this way because it provides a better classical foundation. At least it is better for me to read first before I find other books.

It is broken up into units of proofs, which give you an unadulterated look into the reality of math. It doesn't talk about things; it gives you actual tools.
