On December 3rd, 1942, under the stands at the University of Chicago’s Stagg Field, scientists produced a breakthrough that would change the course of history. There, on that day, physicist Enrico Fermi and his team from the university achieved the primary objective of the top secret Mahattan Project: they initiated the first controlled, self-sustaining nuclear reaction, bringing forth the dawn of the nuclear age.Continue reading “How a Pile of Uranium Changed the World”
