The first lecture of each new year renews for most people a light stage fright.

Mathematics is a dangerous profession an appreciable proportion of us go mad.

The referee said it was not acceptable, but the Press considered they could not refuse to publish a book by a professor of the university.

The first test of potential in mathematics is whether you can get anything out of geometry.

The infinitely competent can be uncreative.

I read in the proof sheets of Hardy on Ramanujan: As someone said, each of the positive integers was one of his personal friends. My reaction was, I wonder who said that I wish I had. In the next proof-sheets I read (what now stands), It was Littlewood who said...

The higher mental activities are pretty tough and resilient, but it is a devastating experience if the drive does stop. Some people lose it in their forties and can only stop. In England they are a source of Vice-Chancellors.

A precisian professor had the habit of saying: ... quartic polynomial ax^4+bx^3+cx^2+dx+e , where e need not be the base of the natural logarithms.
