Larry Fleinhardt, Ph.D., is a fictional character in the CBS crime drama Numb3rs, played by Peter MacNicol. He is the best friend and colleague of Charlie Eppes.
Dr. Lawrence Fleinhardt holds the Walter T. Merrick Chair of Theoretical Physics at the California Institute of Science, CalSci (a university based on Caltech and located in Los Angeles in the Numb3rs universe). He is portrayed as a brilliant theoretical physicist and cosmologist, who researches supersymmetry, string theory, 11-dimensional supergravity theory, doubly special relativity, black holes, Ly-alpha emitters, the cosmic microwave background, and gravitational waves, using LIGO to check predictions on quantum corrections. He may have even found a way to express Calabi–Yau manifolds in a way that goes beyond a nonvanishing harmonic spinor and, independent of Charlie, published a work of genius entitled Zero Point Energy and Quantum Cosmology, which could provide insight into the cosmological constant problem (episode 3x4, "The Mole").
