a recipient of the Milton Prize and a nominee for the Fields Medal. Following his five-year research on random matrices, Charlie worked on sequences with orthogonal symmetry. He has also provided insights for possibly solving the P vs. NP problem and published works on H-infinity control of nonlinear systems and computational fluid dynamics, while his current research is in cognitive emergence theory. He has presented seminars on harmonic analysis and the zeros of random orthogonal polynomials and given lectures on group theory and Kac–Moody algebras. Eppes has taught courses on calculus, chaos theory, fluid dynamics, game theory and probability at CalSci in addition to giving guest lectures on applied probability. The lecture in which he converted the classroom into a miniature casino for analyzing probabilities is considered an "Eppes Classic". Also, Eppes has taken over Fleinhardt's computational physics class when he was asked to do so, and has given a joint lecture on circular motion and the Coriolis effect with Fleinhardt. Professor Otto Bahnoff took over Eppes' mathematical physics grad seminar on the day he got married. Characterization Charlie has wild curly hair, is wary of people, and frequently enthralled with objects and patterns. According to Krumholtz, Charlie wants to understand how the world works. His father has said Charlie is easily fascinated, possesses a big heart and is thorough, but he misses certain things completely. Meanwhile, Larry observed that he is "a talented theoretician with an ego problem" and a student once described him as fast-talking and disorganized, to the agreement of Larry. Fleinhardt also accurately noticed that his colleague has a high standard of guilt and is a pragmatist. Charlie is rather fond of providing excessive explanations (e.g., his discussion of Occam's razor) and reducing complex phenomena to intuitively obvious situations through practical analogies that are quite unlike Larry's metaphysical musings and cosmic metaphors. (These analogies are known as "audience visions" or, as friend Megan Reeves calls them, "those cute little analogies.") While contemplating, his antics and mannerisms may even disconcert more conventional thinkers. Wearing his headset, Dr. Eppes has an intense focusing ability as he voraciously writes equations, often covering several chalkboards with a staccato clacking and the aid of a red chalk holder. Nevertheless, if his line of thought is interrupted during a tense moment, as one of restricted foresight, he can become very disgruntled. Further, when deeply concentrating on a particular problem, it seems Charlie
