Six lectures and examples of an exhibit presented to the Fellows of the Henry Koerner Center for Emeritus Faculty at Yale University by Professor Frank Firk are reproduced here. The lectures were given to colleagues who were experts in fields often far removed from Physics and Mathematics; they are therefore suitable for non-specialist, inquisitive readers. The following topics are covered: 1. Understanding Einstein 2. Nuclear Power and Related Issues 3. The Mysterious Primes 4. New Dimensions - a Tribute to Benoit Mandelbrot 5. Perspective and Beyond 6. E = mc2: a neo-Newtonian Approach 7. Some Examples of Drawings and Paintings from an Exhibition.
