Abstract: The problem of determining the configuration of a rotating self-gravitating mass distribution is an old one, dating back to the time of Newton itself. Most work to date has been for the case of a fluid, like a star, in which the density, velocity, and gravitational potential are the unknowns. The “advantage” in this…
Abstract: Visualization is fundamental to mathematics. The late Fields Medalist Bill Thurston began practicing visualization every day as a first grader. We will practice our visualization and will present visual proofs from combinatorics, analysis, geometry, and topology. Important questions arise including: are visual proofs rigorous?

Abstract: As innovation and technologies associated with man-made transmissions progress, complex and new challenges emerge in radio astronomy due to Radio Frequency Interference (RFI). Hence, novel development of software and hardware to detect and mitigate its effects on scientific data are paramount. In this talk we will discuss the successful implementation of the Generalized Spectral…
Abstract Many high-energy theoretical physicists say that “spacetime is doomed,” that spacetime is not fundamental because it has no operational meaning beyond the Planck scale. In the last decade they have found structures beyond spacetime, such as decorated permutations, which predict the amplitudes for scattering processes of particles in spacetime. We show that decorated permutations…
