Trofim Lysenko, the Stalinist-era biologist who tailored his scientific ideas to suit the Soviet communist party. Denying natural selection and arguing that character traits developed in a parent’s lifetime could be passed onto offspring (like Lamarck), Lysenko put the study of biology in the Soviet Union back by decades. Many actual scientists he competed against […]
This tooth from the mid-6th century contains DNA from the plague, that same pathogen responsible for the Black Death in 14th- Europe. This version of the bubonic plague is known as the “Justinianic Plague,” named after the Byzantine Emperor who reigned during its outbreak in the capital of Constantinople in 541 CE. Many historians have

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

This is an early 14th copy of the _Trotula_, a medical text on women’s conditions. Trota of Salerno was one of the book’s authors. She was from the 1100s, and was called “magistra” or “female master” because her medical knowledge was so respected in her day.
This is a 16th century translation of “The Emerald Tablet”, among the most famous texts on alchemy ever. Although it purports to be from Egypt (that’s where a lot of medieval alchemists thought their sources originated), the first text we know of comes from an Arabic 6th/7th century source. Isaac Newton, himself an occultist, translated

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

The Lechuguilla Cave in south-eastern New Mexico (you can see a photo of part of it in the first slide) is the second deepest in the US (at 1,604 feet), and it runs underground for 150 miles. Located in the Carlsbad Caverns National Park, the cave isn’t open to regular visitors because it includes an
Al-Biruni’s phases of the moon. Fitting image for the lunar eclipse tonight. Biruni was one of the geniuses of astronomical investigation, active in the 11th century during a Golden Age of Islamic science.

This Medieval cemetery from Kilwa Kisiwani, an important historical site on an island of Tanzania, dates back hundreds of years to the heyday of the Swahili Kilwa Sultanate. The Medieval city there was described by the early 14th-century traveler Ibn Battuta as one of the most beautiful in the world — and Ibn Battuta was

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!
Creationists frequently bring up the Piltdown Man to support their idea that scientists deliberately lie about human evolution. True, the Piltdown Man was a famous fake (built by *one* “scientist”) – a supposedly missing link between humans and apes. However, it was actually the scientific community that proved the bones to be a forgery.

The Antikythera Mechanism from Ancient Greece had over 30 gears, and could predict when eclipses would happen, track the irregular orbit of the stars, and figure out when the Olympic games would happen!

Ah! What could be cooler than the 15th-century Voynich Manuscript, a document that has stumped linguists and cryptographers since its rediscovery? Yeah, It’s super fascinating. It uses different letters and people have tried corresponding them to various languages like Latin (it has some Latin words in the margins). The paintings are about medical/”sciency” stuff, and

“The Mushroom Hunters,” a poem by Neil Gaiman, is a feminist paean about science, inspired by history. Some commentary about the history behind the poem: in evolutionary human behavior, much is speculative. “The Mushroom Hunters” draws from many hypotheses made by anthropologists, several of which I have featured stories about. Here are some of them:

Automata are machines that operate on their own, and have been around since Ancient Egyptian times. Often they are automated animals or people designed to impress an audience. This one might give you nightmares. Tragically, the “Automaton of a Friar” that you see here is currently not on display at the National Museum of American
