Description
Join Dr. Trefor Bazett from the Faculty of Science to discuss how much energy is in an atomic bomb? Or even bigger, how much energy is in a supernova? Using nothing more than video footage showing an explosion at different points in time, mathematicians are able to estimate the amount of energy in the 1945 Trinity atomic bomb test.
Learn about the surprisingly powerful–yet simple–technique of dimensional analysis that enables us to make these kinds of estimates.
