We share the same genetic code with people from the Medieval past, and the basic way our brains take in sensory information is also the same. However, the cultural lens of the Middle Ages differs so greatly from our own that Medieval people interpreted the physical world in a vastly different way. This is true […]

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

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 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

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

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

In Frank Herbert’s sci-fi _Dune_ series, the Bene Gesserit are amazing space-witches who have developed such mental control over their unconscious physiology that their powers seem superhuman. But Herbert’s ideas weren’t merely fiction: the person you see here is not a space witch, but she did figure out a technique of controlling elements of human

Here is one of the most famous job advertisements in the history of psychology. In 1971, Professor Philip Zimbardo enlisted a number of highly educated men to participate in an experiment about prison life.

This 17th-century design would make a perfect tattoo, except the meaning would say something pitiable about the wearer. It is a rose with the Latin word “CAUTE” beneath. The rose meant secrecy, and _caute_ means “cautiously.” The person who used this sign, Baruch de Spinoza (1632-1677), did so because he had to constantly keep his

Here come two points about human evolution – the first is one that I imagine is not surprising to you, but the second may be, and might make you wince.First, the animal in this photo is not an ancestor of us Homo Sapiens. We did not evolve from apes but share a common progenitor that

Ancient Hindu and Middle Eastern Islamic surgeons knew a lot about eye cataracts, relatively speaking, and one important medical text, called the _Sushruta Samhita_, exists from about 1500 years ago that detailed how a specialist might remove them from a suffering patient. As this manuscript illustration shows, the knowledge from India made its way to

The dates of the objects in this composite image are far removed from the origin of their subjects: in the background is the Edwin Smith Papyrus, dating from the 17th-century BCE, but ultimately stemming from about 2500 BCE. In the foreground is a Greek Hellenistic statue of Imhotep, the Ancient Egyptian polymath whom many suspect

Today’s social-media aficionados take a lot of personality tests that we know are pure rot, like “what your birth crystal says about the way you treat your pets” or “what your quarantine eating habits reveal about your financial investment patterns.” The bust pictured here reflects similarly outlandish claims from a century and a half ago,

This haunting painting by John Singer Sargent (‘Gassed,’ 1919) shows the horrific consequences of Mustard Gas that nations used against enemy soldiers in the First World War. The hazy yellow skies permeate the atmosphere, as the wounded men make their way across the canvas, many blinded by the hydrochloric acid that survivors attested smelt of
