The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
The legacy of democratic determination is a gift from the Manhattan Project scientists’ habit of openness and their faith in democratic action. This is a legacy worth cherishing and deepening as we seek a world free of nuclear weapons.
A typhoon was coming, the fuel pump failed, they had to switch planes, things were wired incorrectly, they missed their rendezvous, they couldn’t see the primary target, they ran out of gas on the way home, and they had to crash-land.
