I'm reading a very entertaining book by Walter Gratzer called Eurekas and Euphorias. It consists of quite a few, curious or amusing, short tales from the history of science. One of my favorites is about the absent-minded physicist Sir Nevill Mott. One day Mott, who had been a professor of physics in Bristol for many years, was riding the train from London to Bristol when three things struck him at at once:
1) He no longer lived or worked in Bristol, having been appointed Cavendish Professor at Cambridge;
2) He had driven to London that day; and
3) His wife had accompanied him.
