KAREN UHLENBECK WINS THE ABEL PRIZE!

LET’S ALL congratulate Dr. Karen Uhlenbeck. She’s the first woman to win the Abel Prize, one of the world’s top awards in mathematics. One of her mathematical specialities, briefly put, is bubbles, a topic touched on here at SimanaitisSays. And Uhlenbecck is the only mathematician I’ve heard of who credits a famous chef, also a woman, as an inspiration.

The Abel Prize, awarded by the Norwegian Academy of Science and Letters, is named for Neils Henrik Abel, 19th-century Norwegian mathematician. It’s considered right up there with a Nobel Prize (which neglects mathematics as a named category).

Unlike the Fields Medal, which honors mathematicians younger than 40, the Abel Prize has no age specification.

Karen Uhlenbeck, 76, is honored with the Abel Prize “for her pioneering achievements in geometric partial differential equations, gauge theory and integrable systems, and for the fundamental impact of her work on analysis, geometry and mathematical physics.”

Karen Keskulla Uhlenbeck, Cleveland-born 1942, American mathematician. She is emeritus professor and was the first Sid W. Richardson Foundation Regents Chairholder in the Department of Mathematics at the University of Texas in Austin.

Uhlenbeck was awarded a MacArther Fellowship in 1983. She was chosen as a Plenary Speaker at the International Congress of Mathematicians, 1990, only the second woman in history to give such a lecture. Emmy Neother, described by Einstein and others as the most important woman in the history of mathematics, was the first, in 1932.

Uhlenbeck is currently a visiting associate at the Institute for Advanced Study in Princeton, New Jersey. As Kenneth Chang’s article in The New York Times, March 19, 2019, describes, “Dr. Uhlenbeck, who lives in Princeton, N.J., learned that she won the prize on Sunday morning. ‘When I came out of church, I noticed that I had a text message from Alice Chang that said, Would I please accept a call from Norway?’ ”

When Uhlenback got home, she called and learned about the award. Kenneth Chang writes, “she has not decided what to do with the $700,000 that accompanies the honor.”

Uhlenbeck’s—and Plateau’s—Bubbles. “In her early work,” Chang notes, “Dr. Uhlenbeck essentially figured out the shape of soap films in higher-dimensional curved spaces.”

Of these n-dimensional spaces, Uhlenbeck told Chang, “You don’t know ahead of time what the shapes of those minimal soap bubbles are going to be.”

In familiar two- and three-dimensional space, such optimization problems may be straightforward, but they become devilishly complex in higher dimensions, applications of which reside in modern physics.

In 3-space, the interface of two equally sized bubbles is a circular disc. This and the following from “Plateau’s Bubbles,” SimanaitisSays, May 23, 2013.

In “Plateau’s Bubbles,” I described the work of 19th-century French mathematician Joseph Plateau. In particular, he devised an elegant geometric construction describing the interface of two bubbles of any size.

Above, the final constructional step with bubble A and bubble B of different size. Below, the resulting interface.


Uhlenbeck’s Career. Karen Keskulla received her B.A. from the University of Michigan in 1964. She began her graduate studies at the Courant Institute of Mathematical Studies at New York University in 1965, the same year she married biophysicist George Uhlenbeck.

As they advanced in academia, the Drs. Uhlenbeck encountered anti-nepotism practices preventing both from working at the same institution. Divorce in 1976 followed. Karen Uhlenbeck’s career flourished at the University of Texas at Austin, where she was the first Sid W. Richardson Foundation Chairholder in 1988.

Uhlenbeck on Role Models. Kenneth Chang writes, “Dr. Uhlenbeck said she recognized that she was a role model for women who followed her in mathematics. ‘Looking back now I realize that I was very lucky,’ she said. ‘I was in the forefront of a generation of women who actually could get real jobs in academia.’ ”

Her own role model: “Like many people in my generation,” Dr. Uhlenbeck said, “my role model was Julia Child.” ds

    Cheers to Dr. Uhlenbeck, what a phenomena to unravel….my slight brush in this stems from middle school science class and the real life demonstration of “surface tension”, floating paper clips in bowls of water. It is not easy to accomplish, but once done, remains with you the rest of your life, like sighting the aurora borealis from a night flight over the North Pole. Floats my boat, gordon 🙂
