Eclipses and the Theory of Relativity

This picture of the solar eclipse of May 29, 1919, is not only beautiful but also scientifically important. It was taken by British scientist Arthur Eddington (1882-1944), and was the first physical test of Albert Einstein’s General Theory of Relativity. Of course, in retrospect, over 100 years later it might seem obvious that massive objects

Eastern State Penitentiary

The Eastern State Penitentiary in Philadelphia is definitely worth visiting. It was a unique and highly influential prison, and the current site now has first-rate displays with the buildings intentionally kept in a state of semi-decay. The ambience perfectly matched the subject.   Once the USA’s largest prison, Eastern State Penitentiary opened in 1829 with

Baphomet Levi

Baphomet and 19th century Ideologies

The image you see here conjures up the Biblical Satan, but it originates from a 19th-century Christian socialist and has everything to do with a niche occultic revival rather than Biblical ideas about the devil and dark forces. In fact, the illustrator, Eliphas Levi, believed that all religions came from an ancient primitive source, and

Chamberlain-Kahn Act of 1918

This is a photo from 1943 of a detention hospital for infected women in Leesville, Louisiana. And I’m about to deliver a really sad story about the U.S. government’s treatment of women during the 20th century. This is about a series of laws that came to be known as “The American Plan,” and they resulted

Paul Erdos

I would have liked to have met this man, who was as eccentric as this visage here implies. This is none other than Paul Erdös, a Hungarian mathematician who published more papers than any other to date (over 1,500) and worked with so many other scholars (he co-authored with over 500) that math geeks know

Nanteos Cup: Contender for the Holy Grail

Fans of Indiana Jones may remember the film about the Holy Grail, and the part where Indy needs to figure out which of the many ancient cups in front of him was the one Jesus drank from at the Last Supper. Of course, the answer was a drab and utterly innocuous vessel — to match

Yersinia Pestis

Yersinia Pestis

This baddie not only flourished in 14th and 15th century Eurasia. It also killed millions in the 6th cenuury, and struck again in 19th century China. Scientists are now thinking it might have caused a bottleneck in the population of Europeans in the Neolithic era too!

“Mamihlapinatapai”: a Lone Survivor of a Dead Language Spoken by the Yaghan Peoples of Tierra del Fuego

As indigenous peoples around the world encountered Westerners with increasing frequency in the 19th century, many distinctive aspects of their culture were obliterated by the tugs of globalized culture. The Yaghan peoples (a few shown here in this 1883 photo) of the southernmost part of South America in Tierra del Fuego experienced this, but at
