Who, right? http://math.tulane.edu/~tipler/biography.htm.
This guy is a physics professor from tulane who wrote a book called The Physics of Christianity where he claims that physics can prove God exists and the miracles of Jesus. Sounds like it could make for an interesting discussion. Here's the discussion from atheistforums where this was brought up: http://www.atheistforums.com/viewtopic.php?t=2301&highlight=.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!
