Query: A real life "Big Bang Theory"

This is a worthy effort by a "former" physicist. Mlodinow is a postdoc at Caltech in the early 80s who is struggling with the age old question "what should I do with my life"?Sandwiched within his time at Caltech, Mlodinow is heavily influenced by Feynman who is slowly dying of cancer. Feynman's approach to physics (and life as a whole) is explored in a unique fashion in this highly readable memoir.
