There is a common misconception that Native American Indians had no exposure to alcohol before contact with the Europeans. This idea extends to imagining that AmerIndians were genetically less able to metabolize alcohol than the explorers from the Old World. In fact, neither of these ideas are true, as the laws and traditions of the

Focus here, if you will, on the weird corn-on-the-cob part of this image. It features something most of us are unlikely to see, but which we all use every day: the pancreas. And it, like everything we encounter, has a history.The pancreas is hidden deep in the cavity of our guts, behind the stomach. It

This painting by Francois Fleury-Richard shows a scene from the children’s fairy-tale “Little Red Riding Hood.” The illustration dates to about 1820, which is centuries after the original story developed.

Wait: this looks like a science post, but it is really history! Very long-time ago history, like 160 million years ago. But, due to the science of evolutionary genetics, we know this very old story is of immediate relevance to every human, as well as to a very special virus that made our lives possible.Our

This coin dates to the age of the Germanic ruler Clovis I (d 511 CE), and should immediately strike us with its mythological imagery — angels with swords aren’t things we actually see. We realize that the figure on the coin cannot correspond with a real-life person. A tricky thing about studying Early Medieval history,

This fresco from the first-century ruins of Pompeii show that Ancient Roman physicians knew how to practice surgery. In a world without the scientific method, knowledge of germ theory, or antibiotics, doctors could get a lot wrong. However, they got enough right to establish some medical practices that endured for ages, and have influenced medicine

Here lies the effigy of Queen Eleanor of Aquitaine at Fontevraud Abbey. If Queen Eleanor were a Dungeons and Dragons character, she’d be like level fifty. At an imaginary dinner table of bad-ass women in history, Eleanor would stand shoulder-to-shoulder with the likes of Cleopatra of Egypt, the Empress Irene of Byzantium, and Catherine the

When I think of Matthew Hopkins, self-styled “Witchfinder General,” I think about episodes in human history where we really went wrong. This image is from Hopkins’ 1647 book, _The Discovery of Witches_, and shows him overseeing the confessions of women naming their demonic familiars. Under Matthew Hopkins’ short career of three years, about 300 women

Alright, my brainy friends: it won’t take you but a New York minute to look at this diagram and figure out what’s wrong here.That’s right! The earth is in the middle of the entire universe, and of course we know that’s just silly. But such was the model of the cosmos bequeathed by the Ancient

Although other scientists are more famous for getting the astronomical idea of heliocentrism correct, Johannes Kepler (d. 1630) was much more successful than his peers at explaining super important aspects of our solar system (for instance, the planets go round the sun in ellipses). Who would have thought that a driving force behind his significant

So here’s a question for you – will the sun rise tomorrow? I think so, and you do as well (hopefully), but this man showed that you couldn’t prove it.

You are looking at an ecological transformation: what you see here is the former Gunter Valley Dam, which used to block Trout Run in the Tuscarora forest of south-central Pennsylvania.

Here’s Sir Isaac Newton, sporting what looks like some pretty fantastic quarantine hair in his 46th year. Solitary, misanthropic, and quirky (he once experimented on optics by putting a needle deep into his eyesocket to see how his vision would change), Newton’s work on classical mechanics revolutionized how people understood the cosmos. We all can

Like spokes on a wheel, these wide boulevards typify the landscape of Paris. Beautiful components of the city, tourists have come to associate these streets with “La Ville Lumiere”.
