There can be very little of present-day science and technology that is not dependent on complex numbers in one way or another.

Calculus works by making visible the infinitesimally small.

A PhD in Mathematics is three years of guessing it wrong, plus one week of getting it right and writing a dissertation.

Indeed, nowadays no electrical engineer could get along without complex numbers, and neither could anyone working in aerodynamics or fluid dynamics.

I firmly believe that mathematics does not exist outside of humans. It is something we, as a species, invent.

We mathematicians are used to the fact that our subject is widely misunderstood, perhaps more than any other subject (except perhaps linguistics).

The whole apparatus of the calculus takes on an entirely different form when developed for the complex numbers.

Cardinal arithmetic will be quite important for us, so we spend some time on it. Since, however, it tends to be trivial, we shall not need to spend much of this time on proofs.

The linear-programming was - and is - perhaps the single most important real-life problem.

I've never met Hans Rosling, but I just knew him through his many YouTube videos, and they were absolute dynamite.

Given the brief - and generally misleading - exposure most people have to mathematics at school, raising the public awareness of mathematics will always be an uphill battle.

The toughest thing about being a housewife is you have no place to stay home from.

It's hard to hear the story of a love affair between two straight men, one of whom is the most divine woman alive.

If you don't have passion, everything you do will ultimately fizzle out or, at best, be mediocre. Is that how you want to live your life?

I like happy things, I'm really calm and peaceful. I like birds, bees, I like people. I like funny things that make me happy and gleeful... like when my teacher sucked my wee-wee in pre-school!

The solution to a problem changes the nature of the problem.

Note that if I can get you to su and say something just by asking, you have a very serious security problem on your system and you should look into it.

Much sleep is not required by nature, either for our souls or bodies, or for the action in which they are concerned.

I should have known right then it was too good to last, God, it's such a drag when you're livin' in the past

Paradoxical as it may at first appear, the fact is that, as W. H. George has said, scientific research is an art, not a science.
