"The Cows and Colleges Symposium"

Dan Mauldin

R. Daniel Mauldin received his Ph.D. from the University of Texas, Austin, in 1969 under the supervision of H.S. Wall. Dan has written extensively in the areas of set theory, logic, real analysis, dynamics and probability theory among others. His papers are known for their insight, depth and for providing penetrating clarity. He was a friend and frequent collaborator with Paul Erdős and gave one of the plenary lectures at the 2013 Erdős Centennial Conference in Budapest. He has served as Editor for several mathematical journals including the *Proceedings of the AMS *and *Advances in Mathematics*, as well as serving as a Contributing Editor for the * Exchange* for almost twenty years.

In 1982, Dan edited *The Scottish Book: Mathematics from the Scottish Café* and is currently preparing a new edition (This is good too, since new copies of the 1982 edition currently cost more than $2,500). In his lecture Dan will describe some of the unsolved analysis problems in the *Scottish Book.*
