# How Mathematicians Think

Hadamard estimated that :

About

90%of mathematiciansthinkvisually,10%thinkformally.

Usually, they think in steps:

- Get the right idea, often think vaguely about structural issues, leading to some kind of strategic vision;
- Tactics to implement it;
- Rewrite everything in formal terms to present a clean, logical story. (Gauss’s removal of ‘scaffolding’ – middle working steps)

# The Best Job: Mathematician

The above survey was 2009 USA Job Market.

By 2018, Number 1 Job is AI / Data Scientist in USA / China / Europe high-tech market, which still needs Mathematics. eg.

- Linear Algebra (Matrix)
- Calculus (eg. Gradient descent, …)
- Bayesian Statistics (Probability),
- Algebraic Topology (eg. Homological Algebra, etc),
- Abstract Algebra (eg. Category Theory, etc…)
- etc.

# Ultimate Mathematician

引用巴拿赫Banach的名言，体现举一反三的境界：

A mathematician is a person who can find analogies between theorems;

A **better** mathematician is one who can see analogies between proofs

and

The **best** mathematician can notice analogies between theories.

One can imagine that the **ultimate** mathematician is one who can see analogies between analogies.

# Father and son Mathematicians

Mathematics, unlike Medicine, is hardly inherited, as in “Like father like son” running in the family.

There are some exceptions in the history, the most outstanding Mathematician family is Bernoulli.

# Old Mathematicians Live Young

J.J. Sylvester, who coined the term Matrix, pointed out that Leibniz, Newton, Euler, Lagrange, Laplace, Gauss, Plato, Archimedes, and Pythagoras all were productive until their 70s or 80s.

“The mathematician lives long and lives young,” he wrote.

“The wings of the soul do not early drop off, nor do its pores become clogged with the earthly particles blown from the dusty highways of vulgar life.”

Sylvester himself was his 82nd year, in 1896, when he “found a new enthusiasm and blazed up again over the theory of compound partitions and Goldbach’s conjecture.”

Another mathematician Harold S. M. Coxeter (9/2/1907 – 31/3/2003) attributed his longevity to love of mathematics.
