Physics and Photography with PJ Cregg

9plus

Engineering lecturer PJ Cregg recently delivered a captivating talk exploring the intersection of science and art through photography. In this episode, PJ and Rob O’Connor delve into various physical laws depicted in photography, including light reflections and refractions, crepuscular rays (rays of sunlight), and rainbows. They also discuss PJ's research on topics ranging from Claude Shannon’s Information Theory to James Joyce’s Finnegan’s Wake, highlighting the connections between the arts and the sciences.

This episode is inspired by the Mathematics and Physics Seminar series, which has been a cornerstone of intellectual discourse in SETU (and previously WIT and WRTC) since the 1980s (estimated).
