In a recent episode of the Marketplace podcast, a question came up about billionaires. Among several experts, Jordan Ellenberg took a stab at it, suggesting a comparison instead. “How much wealth has that person amassed relative to the sum total of everybody who works for them?” Ellenberg said. “That’s a ratio that’s much closer to a humanly understandable ratio.”
May 2, 2021 marks what would have been Walter Rudin's 100th birthday. Walter Rudin was one of the preeminent mathematicians of his generation. He worked in a number of different areas of mathematical analysis, and he made major contributions to each. He came to the UW in 1959 and stayed until his retirement in 1991. He and his wife, the distinguished mathematician Mary Ellen (Estill) Rudin, were popular teachers at both the undergraduate and graduate level and served as mentors for many graduate students. The duo were active in the daily life of the math department, and enjoyed collaborating with their colleagues as well.
Gage Siebert, of Fremont, Wisconsin, was among three UW-Madison students named as Goldwater Scholars. He is majoring in physics and mathematics. As a freshman, he studied the origins of life in Professor David Baum’s lab at the Wisconsin Institute for Discovery. Siebert then interned at the Arecibo Observatory in Puerto Rico, studying the radio emission from several of the millisecond pulsars used in the search for gravitational waves. He later presented this work at a meeting of the American Astronomical Society. For the past two years, Siebert has worked in Professor Peter Timbie’s observational cosmology lab on the Tianlai Array, a radio astronomy experiment built to map hydrogen. He plans to pursue a Ph.D. in physics.
