If you liked this post, check the BBC podcast Series "A Brief History of Mathematics"[1] and also "The Music of the Primes" from Amazon. It's from the same author.

I recently bought Leonard Susskind's "The Theoretical Minimum" [0] so I could better understand theoretical physics. The explanations are short and clear, but I'm starting to realize that I learn a lot better when I know the historical context in which these concepts developed (or why they were needed). Feynman does this in his lectures and it really helps.
I might really enjoy these podcasts.
