History of the World: Witnessing a Supernova


On July 5, 1054, people all over the world must have been pretty stunned when a giant star bit the dust. The star had burned up its energy, collapsed in on itself and burst from the pressure. It was so bright that it could be seen all over the world - Irish, Japanese, Chinese, Arab and the Anasazi Indians in the New Mexico/Arizona area all have documentation referring to a similar incident during the same time frame. The Europeans almost definitely saw it as well, but documentation is markedly scarce - either they didn't really care or were so scared that they just didn't want to refer to it.

The explosion was so massive that scientists were able to study it 600 years later when the telescope was invented - gas and dust about seven light years from Earth could still be seen. In 1774, it was finally given a name - the Crab Nebula. Apparently someone thought it looked like a crustacean.

A Very Brief History of Chamber Pots

Some of the oldest chamber pots found by archeologists have been discovered in ancient Greece, but portable toilets have come a long way since then. Whether referred to as "the Jordan" (possibly a reference to the river), "Oliver's Skull" (maybe a nod to Oliver Cromwell's perambulating cranium), or "the Looking Glass" (because doctors would examine urine for diagnosis), they were an essential fact of life in houses and on the road for centuries. In this video from the Wellcome Collection, Visitor Experience Assistant Rob Bidder discusses two 19th century chamber pots in the museum while offering a brief survey of the use of chamber pots in Britain (including why they were particularly useful in wartime).
