25 Jan 39: Enrico Fermi, John Dunning and associates split the uranium atom for the first time in the 75-ton cyclotron in the basement of Pupin Hall at Columbia University in New York City. Known as "atom smashers," cyclotrons, first invented in the early 1930s, accelerate atoms through a vacuum and use electromagnets to induce collisions at speeds up to 25,000 miles per second. The results of such experiments provided valuable clues about the behavior of atoms. #WWII #History

Today in WW2 history 1/25/39 the first uranium atom was split @ Columbia University. The Atom Smasher, pictured here, was built from salvaged parts. Enrico Fermi was part of the original experiment. The split atom experiment recorded the release of tremendous energy. The results led FDR in 1942 to order the production of an atom bomb and the Manhattan Project was born.

Robert Oppenheimer, July 1945 Julius Robert Oppenheimer (April 22, 1904 – February 18, 1967) was an American theoretical physicist and professor of physics at the University of California, Berkeley. Along with Enrico Fermi, he is often called the "father of the atomic bomb" for his role in the Manhattan Project, the World War II project that developed the first nuclear weapons.
