I found the following 2 books fascinating: An imaginary tale The Story of SQRT(-1) by Paul Nahin and e: The Story of A Number by Eli Maor

It would be nice to finally agree to separate science and religion. As a Christian and a scientist I accept that these fields should be separate unless you really want to discuss philosophy. Saying you can prove or disprove the existence of God using the profoundly limited nature of the brain must really insult God. Anyway, the Catholic Church discovered may years ago that using religion to suppress science was a monumental disaster. So, let not those professing a "no God theory" make the same blind mistake of using science to suppress religion while bemoaning religion's role of suppressing science throughout our history. Unless they really want to prove the theory that "history always repeats itself".
