Synergistic Activities

MathOverflow is a website for mathematicians to ask and answer research-level questions. It has about 1500 active users who post about 40 new questions every day.

MathOverflow has been responsible for many fruitful collaborations, and has helped many mathematicians overcome technical obstructions in their research. For many professional mathematicians, it has become an extension of how they do mathematics. At the same time, the site is extremely useful for developing mathematicians since it has become a repository for "professional secrets," insights revealed by experts which are for one reason or another difficult to communicate in other media. It is not unusual for an answer to a question to come from the founder of the field!

Notably, much of MathOverflow's traffic comes from small institutions where individual researchers are are alone in their field. Many such mathematicians have told me that MathOverflow has made them happier and more productive. The site has also served an important social role for developing mathematicians since it allows them to freely interact with other mathematicians at all stages in their careers. In this way, the site has filled an important niche, allowing mathematicians to effectively network by doing mathematics together rather than "networking."

Though MathOverflow is a professional forum not targeted at the general public, several general-interest articles have been written about it (for example, a featured article of the Simons Foundation, another in the Atlantic, the San Jose Mercury, as well as posts on several mathematical blogs). In addition to administering, moderating, and participating in MathOverflow, I have done interviews for these articles because I believe it is important to promote mathematics as a whole. In the same spirit, I gave a brief presentation about the site at the 2011 Open Science Summit (slides).
