The Thirty-Sixth Annual
T.G. Ostrom Lecture

Dr. Jean Taylor

"Everything you always wanted to know about soap bubbles"

Wednesday, April 19, 2017

7:00pm in Webster 16

Please join us for an informative discussion by this year's invited guest lecturer Dr. Jean Taylor, Professor Emerita of Mathematics at Rutgers University, and visiting faculty member at Courant Institute of Mathematical Sciences of New York University.

Abstract: The discovery that there was a branch of mathematics that dealt with shapes made Jean Taylor switch from chemistry to mathematics in the middle of graduate school.  Following a man around led her fortuitously to Princeton, where two young faculty members were leading the development of the relatively new field of geometric measure theory. In her Ph.D. thesis, Jean proved that surfaces of minimum total area in a particular class consisted only of smooth surfaces meeting in smooth triple junctions. Within six months, she realized that the general proof of Plateau's rules for the shapes of general soap bubble clusters and soap films on frames was within her grasp. Then within another six months, she learned of whole new fields of interesting shapes she could study, arising in the engineering field of materials science. In this talk, she will convey some of the excitement of discovery along with the things she has learned about soap bubbles and their cousins.

Lecture Reception:

A reception with refreshments will immediately follow the lecture in the Hacker Lounge in Neill Hall, room 216.

About Dr. Taylor:

Jean Taylor was born in San Mateo, California, one of three children of a lawyer and a high school gym teacher. She had never been east of the Rocky Mountains when she left California to attend Mount Holyoke College in Massachusetts. She received her A.B. in chemistry from Mount Holyoke in 1966, graduating first in her class.

Taylor returned to California to enter the graduate program in chemistry at the University of California at Berkeley. Encouraged by some friends in the university hiking club, however, she also audited courses in algebraic topology and differential geometry. Although she switched her emphasis to mathematics, Taylor still earned her master's degree in physical chemistry in 1968. She then left Berkeley to marry her boyfriend, a mathematician who had gone to study in England. In 1971 she earned a second master's degree in mathematics from the University of Warwick.

Taylor returned to the United States to begin a doctoral program in mathematics at Princeton. She received her Ph.D. in 1973 under the supervision of Frederick J. Almgren, Jr. Her dissertation on "Regularity of the Singular Set of Two-Dimensional Area-Minimizing Flat Chains Modulo 3 in R3" solved a long standing problem about length and smoothness of soap-film triple function curves. It was published in Inventiones Mathematicae, Vol. 22 (1973), pp.119-159 [Abstract].

Upon her graduation from Princeton, Taylor joined the faculty of mathematics at Rutgers University as an assistant professor. She also married Frederick Almgren in October 1973. Taylor remained at Rutgers for her entire professional career, rising through the ranks to Professor of Mathematics in 1982. She retired in 2002. Taylor has authored over 90 publications and given over 150 invited lectures both in the United States and abroad. She has been elected a Fellow of the American Association for the Advancement of Science (AAAS), the Association for Women in Science, and the American Academy of Arts and Science. Taylor served as a Vice-President of the American Mathematical Society from 1995-1997, as a member of the Board of Directors of AAAS from 1995-1999, and in 1999 began a two year term as President of the Association for Women in Mathematics.

Taylor's research has focused on problems related to soap bubbles and crystals, and how they evolve under various physical laws. She has done pathbreaking work in the mathematics of minimal surfaces. She is well known for her Scientific American article on "The Geometry of Soap Bubbles and Soap Films" written in 1976 with her husband, Fred Almgren. Taylor has been described as an "experimental mathematician" who does experiments as a motivation for ideas, but then tries to prove that what she sees is what you have to get. Her recent research has included interdisciplinary, joint work with materials scientists, particularly with a group at the National Institute for Standards and Technology. She is interested in developing and understanding mathematical models for crystal growth.

When not involved in mathematics, Jean Taylor spends many hours as a rock climber and accomplished mountain hiker, a hobby that began in college. She and her husband, who died in February 1997, raised three children. Robert Almgren is a mathematician at the University of Chicago. Ann Almgren works as a scientist in the field of computational fluid dynamics at the Lawrence Berkeley National Laboratory. The youngest daughter, Karen, was a mathematics major at the Massachusetts Institute of Technology.
