UNC-CH Physics and Astronomy Colloquium Virginia Kilborn, Swinburne University “Tracing the gaseous surrounds of galaxies” Observations of the neutral atomic hydrogen (HI) component of galaxies is a powerful mechanism to probe the physical properties of galaxies in the nearby Universe. … Read more

UNC-CH Physics and Astronomy Colloquium David Albert, Columbia University “How to teach Quantum Mechanics - Part II” I distinguish between two conceptually different kinds of physical space: a space of ordinary material bodies, which is the space of points at … Read more

UNC-CH Physics and Astronomy Colloquium Aaron Titus, High Point University “Iterative Thinking” Numerical techniques for integration are hardly taught in a typical calculus course and are hardly used in a typical physics course. Yet, numerical integration is an essential tool … Read more

UNC-CH Physics and Astronomy Colloquium Carl Bender, Washington University in St Louis “PT Symmetry” By using complex-variable methods one can extend conventional Hermitian quantum theories into the complex domain. The result is a huge and exciting new class of parity-time-symmetric … Read more

UNC-CH Physics and Astronomy Colloquium Piers Coleman, Rutgers University “Dark Matter Challenges of the Solid State” At the turn of the 20th century, physicists faced an uncanny range of unsolved problems: simple questions, such as why hot objects change color, … Read more
