History

First Test of a Nuclear Weapon

Called the Trinity test, the first test of a nuclear weapon was conducted by the US in New Mexico on what is now White Sands Missile Range. The detonation of the implosion-design plutonium bomb—the same type used on Nagasaki, Japan, a few weeks later—was equivalent to the explosion of approximately 20 kilotons of TNT, and is usually considered the beginning of the Atomic Age. It is said that the scientists who observed the detonation set up a betting pool on what the result would be. Who won?

Classified Information in the US

The US government has three levels of classification: "confidential," "secret," and "top secret." Each level of classification indicates an increasing degree of sensitivity, which is based upon a calculation of the damage that the release of the information would cause to national security. The current classification system was established under Executive Order 13292, which was issued by President George W. Bush in 2003. Why do some speculate that there may be a level "above" top secret?
