A mathematician is someone who is professionally engaged in the field of mathematics, which is the study of numbers, quantities, structures, spaces, and the relationships between them. Mathematicians can work in various areas, including pure mathematics (theoretical aspects that explore mathematical concepts and ideas for their own sake) and applied mathematics (using mathematical theories and techniques to solve practical problems in fields such as engineering, physics, economics, biology, and computer science).

A mathematician develops and studies mathematical structures, formulates conjectures, constructs mathematical proofs and designs methods for solving problems. Work can emphasize foundational theory, computational methods or applications to scientific models; these activities often interact.
For example, a question about stable numerical methods may require a theorem in functional analysis, while a geometric example can reveal the right algebraic definition. The list of mathematicians connects individual contributions with the reusable mathematical ideas they helped establish.
Poet, scientists and warriors all in one? Conquerors of the useless.
A wise teacher from University of São Paulo once told the class Ciro Santilli attended an anecdote about his life:It turned out that, about 10 years later, Ciro ended up following this advice, unwittingly.
I used to want to learn Mathematics.But it was very hard.So in the end, I became an engineer, and found an engineering solution to the problem, and married a Mathematician instead.
