Date/Time: Wednesday September 10, 2025 starting at 7:30PM Location: University of Victoria, Bob Wright Centre, Lecture Theatre A104. The recent discoveries by JWST et al regarding the early, quick formation of galaxies are leading scientists to question the status quo mechanisms of galaxy creation. In this talk, a scientist-from-another-mother brings a multidisciplinary approach to this question that incorporates dissipative (friction) forces, thermodynamics. free body mechanics, and even chemistry to the non-linear dynamics involved.
