mathematician

Leonhard Euler, considered one of the greatest mathematicians of all time

A mathematician is a person whose primary area of study and research is the field of mathematics.

Problems in mathematics

Some people incorrectly believe that mathematics has been fully understood, but the publication of new discoveries in mathematics continues at an immense rate in hundreds of scientific journals. One of the most exciting recent developments was the proof of Fermat's last theorem, following 350 years of the brightest mathematical minds attempting to settle the problem.

There are many famous open problems in mathematics, many dating back tens, if not hundreds, of years. Some examples include the Riemann hypothesis (from 1859) and Goldbach's conjecture (1742). The Millennium Prize Problems highlight longstanding, famous problems in mathematics and offers a US$1,000,000 reward for solving any one of them. One of these problems, the Poincaré conjecture (1904), was proven by Russian mathematician Grigori Perelman in a paper released in 2003; peer review was completed in 2006, and the proof was accepted as valid. [1]

Motivation

Mathematicians are typically interested not in calculating, but in finding and describing patterns, or creating proofs that justify a theorem mathematically. Problems have come from physics, economics, games, computer science and generalizations of earlier mathematics. Some problems are simply created for the challenge of solving them. Although much mathematics is not immediately useful, history has shown that eventually applications are found. For example, number theory originally seemed to be without purpose to the real world, but after the development of computers it gained important applications to algorithms and cryptography.

There are no Nobel Prizes awarded to mathematicians. The award that is generally viewed as having the highest prestige in mathematics is the Fields Medal. This medal, sometimes described as the "Nobel Prize of Mathematics", is awarded once every four years to as many as four young (under 40 years old) awardees at a time. Other prominent prizes include the Abel Prize, the Nemmers Prize, the Wolf Prize, the Schock Prize, and the Nevanlinna Prize.

Differences

Mathematicians differ from scientists in that physical theories in the sciences are usually assumed to be an approximation of truth, while mathematical statements are an attempt at capturing truth. If a certain statement is believed to be true by mathematicians (typically because special cases have been confirmed to some degree) but has neither been proven nor disproven to logically follow from some set of assumptions, it is called a conjecture, as opposed to the ultimate goal: a theorem that is proven true. Physical theories may be expected to change whenever new information about our physical world is discovered. Mathematics changes in a different way: new ideas don't falsify old ones but rather are used to generalize what was known before to capture a broader range of phenomena. For instance, calculus (in one variable) generalizes to multivariable calculus, which generalizes to analysis on manifolds. The development of algebraic geometry from its classical to modern forms is a particularly striking example of the way an area of mathematics can change radically in its viewpoint without making what was proved before in any way incorrect. While a theorem, once proved, is true forever, our understanding of what the theorem really means gains in profundity as the mathematics around the theorem grows. A mathematician feels that a theorem is better understood when it can be extended to apply in a broader setting than previously known. For instance, Fermat's little theorem for the nonzero integers modulo a prime generalizes to Euler's theorem for the invertible numbers modulo any nonzero integer, which generalizes to Lagrange's theorem for finite groups.

Demographics

While the majority of mathematicians are male, there have been some demographic changes since World War II. Some prominent female mathematicians are Emmy Noether (1882 - 1935), Sophie Germain (1776 - 1831), Sofia Kovalevskaya (1850 - 1891), Rózsa Péter (1905 - 1977), Julia Robinson (1919 - 1985), Mary Ellen Rudin, Eva Tardos, Émilie du Châtelet, Mary Cartwright, Hypatia of Alexandria, Marianna Csörnyei, Ingrid Daubechies and Nicole El Karoui. The AMS and other mathematical societies offer several prizes aimed at increasing the representation of women and minorities in the future of mathematics.

Doctoral degree statistics for mathematicians in the United States

The number of doctoral degrees in mathematics awarded each year in the United States has ranged from 750 to 1230 over the past 35 years. [2] In the early seventies, degree awards were at their peak, followed by a decline throughout the seventies, a rise through the eighties, and another peak through the nineties. Unemployment for new doctoral recipients peaked at 10.7% in 1994 but was as low as 3.3% by 2000. The percentage of female doctoral recipients increased from 15% in 1980 to 30% in 2000.

As of 2000, there are approximately 21,000 full-time faculty positions in mathematics at colleges and universities in the United States. Of these positions about 36% are at institutions whose highest degree granted in mathematics is a bachelor's degree, 23% at institutions that offer a master's degree and 41% at institutions offering a doctoral degree.

The median age for doctoral recipients in 1999-2000 was 30, and the mean age was 31.7.

The following are quotations about mathematicians, or by mathematicians.

A mathematician is a machine for turning coffee into theorems.

—Attributed to both Alfréd Rényi [3] and Paul Erdős

Die Mathematiker sind eine Art Franzosen; redet man mit ihnen, so übersetzen sie es in ihre Sprache, und dann ist es alsobald ganz etwas anderes. (Mathematicians are [like] a sort of Frenchmen; if you talk to them, they translate it into their own language, and then it is immediately something quite different.)

—Johann Wolfgang von Goethe

Some humans are mathematicians; others aren't.

—Jane Goodall (1971) In the Shadow of Man

Each generation has its few great mathematicians...and [the others'] research harms no one.

—Alfred Adler, "Mathematics and Creativity"^[1]

Mathematics, rightly viewed, possesses not only truth, but supreme beauty -- a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show.

—Bertrand Russell, The Study of Mathematics

Another roof, another proof.

—Paul Erdős

Some of you may have met mathematicians and wondered how they got that way.

—Tom Lehrer
