Trinity (atomic explosion)
A test, code-named Trinity, was the first atomic explosion in world history, on July 16, 1945. It occurred in a remote location in the middle of New Mexico, on what is now the White Sands Missile Range.
Robert Oppenheimer named it Trinity after reading the sonnet by John Donne: "Batter my heart, three-personed God, for you/ As yet but knock, breathe, shine and seek to mend..." The scientists considered the name appropriate for something Godlike.
The atomic bomb that exploded was the implosion-design plutonium bomb, equivalent to what was later dropped on Nagasaki, Japan. The detonation was equivalent to the explosion of 20 kilotons of TNT. The Test was concieved out of the Manhattan Project, the Allied effort to build new powerful weapons using nuclear fission.
The 51,500 acrea site is now a National Historic Landmark, and visits can be made to the site in April and October, as it is too hot in July.
