MySci Daily Round-Up, July 16: Atomic Cafe

On this day in 1945, the 
Trinity test, the first-ever atomic bomb explosion, was staged on the Alamogordo Bombing and Gunnery Range, about 230 miles south of the Manhattan Project’s headquarters at Los Alamos, NM. Manhattan Project technical director J. Robert Oppenheimer gave the test its code name, Trinity, which was inspired by a line from a John Donne sonnet: “Batter my heart, three-personed God.” After being delayed by a thunderstorm, the device was detonated at 5:45 a.m., creating a flash that could be seen across New Mexico and in three other states, and sending a mushroom cloud rising to a height of 38,000 feet within minutes. The blast, the equivalent of 20,000 tons of TNT, raised the temperature at ground zero to about 10,000 times that of the Sun’s surface. Seeing his handiwork, the well-read Oppenheimer reportedly quoted a line from a Hindu sacred text, the Bhagavad-Gita:  “I am become death, the shatterer of worlds.” And with that cheery thought, here are the stories of the day.
