In the early morning hours of July 16, 1945, some of the greatest scientific minds of a generation gathered in the New Mexican desert to watch the results of their unprecedented, world-changing experiment: to build the most powerful weapon in the world. But when they pressed the button on their bomb, nicknamed “Gadget,” they weren’t quite sure what would happen.
The general consensus was that the bomb would yield energy equivalent to 5,000 tons of TNT (the actual result as it was finally calculated was 21,000 tons). Robert Oppenheimer, the director of the Manhattan Project, had bet ten dollars against scientist George Kistiakowsky’s wager, with his entire month’s pay, that the bomb would not work at all. Enrico Fermi offered a wager on “whether or not the bomb would ignite the atmosphere, and if so, whether it would merely destroy New Mexico or destroy the world.”
