The lesson of the story might appear to be that self-interested and ambitious people in power are often the cause of wastefulness in developing countries. But self-interested and ambitious people are in positions of power, great and small, all over the world. In many places, they are restrained by the law, the press, and democratic opposition. Cameroon's tragedy is that there is nothing to hold self-interest in check. -- Tim Harford

I think it is wise, and only honest, to warn you that my goal is immodest. It is not my purpose to "transfer knowledge" to you that, subsequently, you can forget again. My purpose is no less than to effectuate in each of you a noticeable, irreversable change. I want you to gain, for the rest of your lives, the insight that beautiful proofs are not "found" by trial anf error but are the result of a consciously applied design discipline. I want you to raise your quality standards. I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself "Dijkstra would not have liked this", well, that would be enough immortality for me. -- E. W. Dijkstra

Software is like sex: It’s better when it’s free. -- Linus Torvalds

The proof is by reductio ad absurdum, and reductio ad absurdum, which Euclid loved so much, is one of a mathematician’s finest weapons. It is a far finer gambit than any chess gambit: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game. -- G. H. Hardy

A person won't retain proficiency at a task unless he or she has at one time learned to perform that task very rapidly. Learning research demonstrates that the skills of people who become accurate but not fast deteriorate much sooner than the skills of people who become both accurate and fast. -- Philip Greenspun

I would rather be an optimist and be wrong than a pessimist who proves to be right. The former sometimes wins, but never the latter. -- "Hoots"

I have learned over the years that when one's mind is made up, this diminishes fear. –Rosa Parks

If you're offered a seat on a rocket ship, don't ask what seat! Just get on. –Sheryl Sandberg

We become what we think about most of the time, and that’s the strangest secret. ~Earl Nightingale
