## Mathematical experiment: a lost art.

**Halmos, Paul R.**

Mathematics is not a deductive science — that’s a cliche. When you try to prove a theorem, you don’t just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork.

*I Want to be a Mathematician*, Washington: MAA Spectrum, 1985.

*The other extreme would be: doing only experiment in mathematics and claim that it is true in general. This should be written in: I want to be a Non-mathematician. *

## Are you one of them?

**Lang, Andrew (1844-1912)**

He uses statistics as a drunken man uses lamp posts — for support rather than illumination.

*Treasury of Humorous Quotations.*

## The beauty of mathematics

**Hadamard, Jacques**

The shortest path between two truths in the real domain passes through the complex domain.
