Questions & Answers

Q: How did Ed Uh transition from being a history major to winning the Fields Medal in mathematics?

Ed Uh recognized his talent for math and physics at the age of 21 and decided to pursue graduate studies in physics. Exciting discoveries in elementary particle physics during that time, including the J/ψ particle and the establishment of the standard model, solidified his interest in the field.

Q: What specific discoveries in elementary particle physics excited Ed Uh?

Ed Uh was initially unaware of the specific discoveries in elementary particle physics when he made the decision to pursue physics. However, the period of discovery, including the J/ψ particle and the establishment of the standard model, captivated him and drove his interest in the subject.

Q: What mathematics was required for the standard model that was unfamiliar to physicists and mathematicians at the time?

The mathematics required for the standard model was non-abelian gauge theory, which extended Maxwell's linear equations to a non-linear version. This extension allowed for the interaction and scattering of waves, necessitating quantum mechanical treatment. Solving the equations of the standard model was a challenging problem and remains largely unsolved today.

Q: How did Ed Uh's interest shift from the standard model to string theory?

Ed Uh's interest in the mathematical issues arising in the standard model led him to explore the application of physics to mathematics. In the mid-80s, progress in string theory opened up a new arena for the application of physics, sparking Ed Uh's transition to studying string theory.
