A MATHEMATICIAN A DAY
by Kathy Wilson
An international portrait gallery
of sketches of contemporary mathematicians
These small sketches were done during lecture presentations
at seminars and conferences
in the United States, China, Japan, Iran
and South Korea.
Each entry consist of one of these sketches, and the title of the lecture
during which it was drawn, as well as the country of origin.
