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

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.

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.

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

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.

There’s something about being naïve. Really interesting things come because you don’t know what the rules are, what you can and can’t do.

He came to destroy sin because it is fatal.

The safe place lies in obedience to God's Word, singleness of heart and holy vigilance.

I guess I'm attracted to more archaic words because they can be imbued with more meaning, because their definition is elusive.

The man who is afraid to risk failure seldom has to face success.

Poor Al Gore, global warming completely debunked, via the very Internet you invented.

What we do, if we are successful, is to stir interest in the matter at hand, awaken enthusiasm for it, arouse a curiosity, kindle a feeling, fire up the imagination.

Stale water is a poor drink. Stale skill is worse. And the man who walks in his own footsteps only ends where he began.

Nihilism is not an existential quandary but a speculative opportunity.
