The Fantastic Mr. Feynman and one of the phrases I most like:
“We make no apologies for making these excursions into other fields, because the separation of fields, as we have emphasized, is merely a human convenience, and an unnatural thing. Nature is not interested in our separations, and many of the interesting phenomena bridge the gaps between fields.”
I also strongly recommend his book: Surely You’re Joking, Mr.
Feynman!: Adventures of a Curious Character.
PS.: Thanks Debora Milori for recommending this great documentary.
