# What Do Mathematicians Do?

Mathematicians are often asked by friends, family, colleagues in** **other fields, and strangers: "What do mathematicians do?" Here are some resources and facts that may help answer that question.

- "What Are You Going to Do with That?" – a blog post by mathematician Evelyn Lamb on the many possible career paths one can take.
- Some of What Mathematicians Do, by Martin H. Krieger,
*Notices of the AMS* *Occupational Outlook Handbook: Mathematicians*, U.S. Department of Labor, Bureau of Labor Statistics. The page includes significant points about the nature of the work.- "What do mathematicians do?," by Jason Rosenhouse
- "Mathematical Careers," by Joe Malkevitch – an historical perspective

## Many people are familiar with mathematicians in academia, but mathematicians also work in many other fields, including:

- Astronomy and space exploration
- Climate study
- Medicine
- National security
- Robotics
- Animated films
- and in a wide range of businesses (Theory Into Profit: Microsoft Invests in Mathematicians, by Allyn Jackson,
*Notices of the AMS*, and Mathematical Experiences in Business, Industry and Government, by Phil Gustafson,*MAA Focus*)

The diversity of fields that employ mathematicians is reflected in Mathematical Moments and Mathematics and Statistics Awareness Month themes.

Mathematicians make it possible to send secure emails and buy things online. Mathematicians are essential to analyze data and design accurate models in fields as diverse as biology and finance. Mathematicians enabled researchers to complete The Human Genome Project quickly. And because of the prevalence of the computer at work and at play, mathematicians will continue to touch everyone in modern society.

## How Many Mathematicians Are There in the U.S.?

There are over 35,800 individual members of the four leading professional mathematical sciences societies in the U.S.---the AMS, the Association for Women in Mathematics, the Mathematical Association of America, and the Society for Industrial and Applied Mathematics. Most would call themselves mathematicians; many received their doctoral degrees outside the U.S. There are at least 10,000 more members of the societies who are graduate students or in other categories, and there are also mathematicians who are not members of any of these societies.

Although they have advanced degrees in mathematics, many of those employed in academia might call themselves professors instead of mathematicians, and similarly, those in industry and government may not have "mathematician" in their job title. The job title doesn't tell the whole story, however: These people are doing mathematics and are indeed mathematicians. Furthermore, the number of mathematicians is increasing. The number of new Ph.D.'s in the U.S. has gone up every year since 2002.

## Who *Are* Mathematicians?

Mathematicians are people of all ages and from all over the world who enjoy the challenge of a problem, who see the beauty in a pattern, a shape, a proof, a concept. Some of the best young mathematicians compete in math olympiads, state and national science fairs, or go to summer Math Camps to learn more and work with teams on projects; undergraduates can also participate in Summer Research Experiences. Many carry on their research and teach at colleges and universities, while others apply their skills in all kinds of professions. There's probably a bit of the "mathematician" in all of us and we don't even realize it. Keith Devlin poses this idea in his book, *The Math Instinct: Why You're a Mathematical Genius (along with Lobsters, Birds, Cats, and Dogs)*. In any case, those who are not "mathematicians" can appreciate the subject by reading about mathematicians, breakthroughs in mathematics, and current applications at Math in the Media.

## Resources on the Mathematics Profession:

- Congressional Briefings. Mathematicians advocate for the importance of mathematics as they present the latest advances in mathematics research to Congressional representatives who vote to fund the National Science Foundation and other governmental agencies.
