In the panic following the 1957 Sputnik launch, the United States seriously studied detonating a nuclear weapon on the Moon as a show of force. Code-named Project A119 under the bland cover title "A Study of Lunar Research Flights," the initiative tasked a team at the Illinois Institute of Technology, led by physicist Leonard Reiffel, with figuring out how to make a nuclear flash visible to the na...

In 1921, a Chicago jury acquitted eight White Sox players accused of throwing the 1919 World Series to the Cincinnati Reds.
