in Feynman diagrams is replaced with summation over the discrete momentum eigenvalues whose separation increases with magnitude. Consequently, divergent integrals in Feynman diagrams are replaced with convergent sums. Therefore, torsion might eliminate ultraviolet divergence and provide a physical mechanism for regularization in quantum field theory, giving finite values of bare quantities such as the mass and electric charge of the electron. Education Popławski received his M.S. degree in astronomy from the University of Warsaw (1999), and his Ph.D. degree in physics from Indiana University (2004), where he later worked as a lecturer and researcher in theoretical physics. He joined the Department of Mathematics and Physics at the University of New Haven as a senior lecturer in 2013 and became a distinguished lecturer in 2020. In popular culture Popławski appeared in an episode of the TV show Through the Wormhole titled "Are There Parallel Universes?" (season 2) and in an episode of the Discovery Channel show Curiosity titled "Is There a Parallel Universe?", which aired in 2011.
