Another good reason to follow the National Archives on Twitter, Tumblr and other media: Great updates.
Like this one on the explosive arrival of the Atomic Age:
On July 16, 1945 the United States tested a nuclear device, code named “Trinity”, for the first time in White Sands Proving Ground, New Mexico.

It’s astonishing to think anyone could hide the explosion today. Near the end of World War II, after Germany had surrendered to end the war in Europe, no one really knew just what at atomic explosion would look or sound like. The test occurred near dawn in a very desolate part of New Mexico’s southern desert, a then sparsely populated state. A few thousand may have seen the flash; a few hundred may have heard or felt the explosion. No one in government confirmed any report of a weapon.
