John Baez (August 2009)

John Carlos Baez (born June 12, 1961 in San Francisco ) is an American mathematical physicist and professor at the University of California , Riverside .


Baez graduated from Princeton University with a bachelor's degree in mathematics in 1982 and received his doctorate in 1986 from Irving Segal at the Massachusetts Institute of Technology ( Conformally invariant quantum fields ). He was a post-doctoral student at Yale University and has been teaching mathematics at the University of California at Riverside since 1989.

Among other things, John Baez works in the areas of loop quantum gravity (spin foam, spin networks) and category theory and the general application of algebraic structures in physics . The cobordism conjecture comes from him and James Dolan .

John Baez is best known for his presence on the Internet , in particular for his This Week's Finds in Mathematical Physics column, which has been appearing at irregular intervals since 1993 , in which he writes on various topics in physics and mathematics , and which he writes in several Usenet newsgroups and on published on his homepage. He is also one of the founders of the group blog n-Theory-Café on higher category theory.

In 2010, worried about global changes such as climate change , he decided to turn to applications and is at the same time at the Center for Quantum Technologies at the National University of Singapore . He started the scientific discussion forum Azimuth Project on the topic of global climate change .

For 2013, he and John Huerta (his PhD student) were awarded the Levi L. Conant Prize . He has been a Fellow of the American Association for the Advancement of Science since 1999 .

Joan Baez is his cousin and her father, the physicist Albert Baez (1912–2007), is his uncle. John Baez is married to Lisa Raphals, a professor of Chinese and literature at UC Riverside.
