QOTD

Found in an excerpt by a book by the former wife of Stephen Hawking:

Nor, I have to confess, did the set of scientists with whom Stephen was now associating attract me in the least. On the whole, particle physicists were a dry, obsessive bunch of boffins, little concerned with personal contact but very concerned with their own scientific reputations. They were much more aggressively competitive than the relaxed, friendly relativists with whom we had associated in the past.
