The ultimate showdown between brute force and big brain energy! On the left, we've got the entire U.S. military desperately guarding nuclear secrets with explosions, soldiers, and classified documents. On the right? Just one British mathematician with glasses, dimensional analysis, and a single photograph who managed to crack the nuclear code anyway. This is Geoffrey Taylor, who famously estimated the yield of the Trinity nuclear test using nothing but a photo of the explosion and some basic physics principles. While the Americans were like "NOBODY CAN KNOW OUR SECRETS," Taylor was like "Hold my tea" and calculated it on the back of a napkin. Talk about embarrassing the entire military-industrial complex with just a pencil!
