When you’re in the mood to play a song or two, you could grab a guitar or sit down at a piano. But for some Massachusetts residents, typewriters are the instruments of choice. The Boston Typewriter Orchestra was founded in 2004 and its members use old typewriters to produce unique sounds that they turn into music—they’ve even released an album.

People Didn’t think the earth was flat in the middle ages

Since the time of Aristotle, the fact that the Earth is round has been accepted nearly universally among European intellectuals. So, if you taught that Columbus couldn’t get financing for his voyage because people thought he was going to sail over the edge of the Earth, you were taught wrong.
