Graduation ceremonies are in abundance in many parts of the world right now, and I love to point out just how Medieval these ceremonies are. Y’all in the robes — you’re Cosplaying, because those outfits are from back in the Middle Ages. And relative to another tradition from these times is the university ceremonial mace, […]

This is Polly Matzinger, and even though this is a history Instagram post, she is an active scientist. But her discoveries about the way the immune system works have changed how scientists think about the ways living things fight off harmful pathogens, thus ensuring Matzinger a place in humanity’s historical records.Before I say anything about

If you are reading this post, I hope you can celebrate the fact that your profession is not as wretched as the Resurrectionists of Britain, and your post-mortem reputation as wretchedly public as that of William Burke, a Resurrectionist so desperate that he became a murderer for his career.In the 18th and 19th centuries, scientists

Time for an amusing Ancient Greek philosophers anecdote. This one is about the clash between Diogenes of Sinope (d 323 BCE) and the famed Athenian philosopher Plato.According to Diogenes Laëtius (no relation – he lived about 500 years after but preserved ancient sources), Plato had defined men as featherless bipeds. This provoked the OG Diogenes

This is a photo from about 1930 of the “Relay Assembly Test Room,” from the factory known as the Hawthorne Works, operated by Western Electric and site of a famously studied phenomenon in psychology called “the Hawthorne Effect”.Starting in 1924, Western Electric sponsored a series of experiments on the effect of lighting and efficiency in

This small bronze figure comes from 5th-century BCE Sparta, when the Ancient Greek polis was at the height of its power. Contemporaries and later Ancients had much to report on the education of Spartan boys at this time, which was infamously brutal and unique. Starting at age 7, boys were grouped into “herds” — the

Here are four different species of finches from the Galapagos Islands. Although they look similar, their differences include their beaks — each one takes advantage of a different type of seed. Natural selection shaped the trajectory of these birds’ appearance, and one of the scientists who first figured out how this worked passed away yesterday

You are looking at an artist’s rendition of a device known as “the staff of al-Tusi” which sounds like a magical weapon straight out of Tolkien but in fact was a genius scientific tool made by one of the most important mathematicians in history. Sharaf al-Din al-Muzaffar al-Tusi (c. 1135-1213) lived in various cities

This is a book that of which I am not a fan. _The Alphabet Versus the Goddess_, by Leonard Shlain, argues that the development of the written word allowed patriarchy to flourish. Sigh. Shlain’s background was in surgery, and the premise of his thesis is rooted in physical claims. “Alphabet literacy,” he asserts, gains

You are looking at a tiny opening, maybe three feet wide and two feet high, that peers into a hidden room against a stairwell that served as one of the first stopping points of the northbound path of America’s Underground Railroad. The Underground Railroad, of course, was the illegal highway that American enslaved people
This is a drawing of the prehistoric species Plesiosaurus, discovered by the paleontologist Mary Anning in 1823. Anning was a working-class, uneducated person who became one of England’s premier fossil scholars, but struggled her whole life — financially and professionally — because of her gender and class. Anning grew up on the southern coast

Ah, the poor doomed philosopher Giordano Bruno. Whereas Galileo had been allowed to live after recanting his astronomical views that ran counter to Roman Catholic teachings, Bruno — himself a Dominican friar — was executed by the Church in 1600. His death and his willingness to buck the Catholic Church’s stranglehold on acceptable views about

Wanna be a smidge happier? Learn about an extremely rare illness discovered in 1882 by the French neurologist Dr. Jules Cotard — if you can read this post, you almost certainly don’t have it. And for that, you will be gladdened. At his hospital at the Pitié-Salpêtrière University in Paris, the doctor saw a patient

Take a guess as to what this Medieval illustration is a drawing of: upside-down fallopian tubes? Sea-creatures? Mirror-image diagrams of some planetary motion? The answer is below, but before you look — ask yourself how you are arriving at your guesses. The process of investigative inquiry to figure out the nature of reality is something

This grizzly painting of two polar bears rending apart the remains of human corpses with a shipwreck in the background is the subject of a fascinating urban legend. Called _Man Proposes, God Disposes_, it was painted by artist Edwin Landseer in 1864 to depict the tragic failure of Englishman Sir John Franklin’s Arctic expedition 19

I love that as I get ready to write up my syllabi for this coming fall semester, perhaps a wee bit wistful of my fabulous summer coming to an end, I am reading about a time in the early 20th century when teaching college students was a lot more stressful. And that’s where the great

Flick through these three images, dear readers, and you will observe something that scholars have been looking for for over 2,000 years — finally brought to light via a student class project, the COVID lockdowns, and state-of-the-art multispectral imaging. It is the oldest star map of the universe. The manuscript you see is the _Codex

The initials “WN” on this board from 1857 stand for “Welsh Not” — this cruel form of student discipline in Welsh schools in the 19th century goes a long way to illustrating why the language has almost died out. The Welsh Not (also called Welsh knot, Welsh note, Welsh ticket, among other terms) was usually
The way cutting-edge technology lets us see into the distant past is so cool. Recently, a technique called “photometric stereo workflow” enabled Medieval historian Jessica Hodgkinson take a fresh appraisal of the pages of a manuscript written in south-east England in the first half of the 700s. The historian discovered that the name of a
