Programming is one of the most difficult branches of applied mathematics; the poorer mathematicians had better remain pure mathematicians.

Computer science is no more about computers than astronomy is about telescopes.

The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise.

Simplicity and elegance are unpopular because they require hard work and discipline to achieve and education to be appreciated.
