Just thought I'd point out that this is utterly incorrect. It is a common myth that Einstein was a theist. In fact, there are many quotes from him explicitly stating that he does NOT believe in God, or at very least not in the form everyone expects. In a letter in 1954, he said "I do not believe in a personal God and I have never denied this but have expressed it clearly.” Clear enough?
In fact, with Einstein you could craft a very effective anti-religion, or at least anti-Christian, view of the world. To quote: "The word God is for me nothing more than the expression and product of human weakness, the Bible a collection of honorable, but still purely primitive, legends which are nevertheless pretty childish." A pretty damning verdict, I'd say.
This is just something that gets my goat, sorry for being so pedantic about it. And even if we DID count Einstein as a theist, you'd have to disregard just about every other great scientist of modern times. Nikola Tesla, Santiago Cajal, O.W. Holmes, et cetera.
