The symbol you see here that means “prescription” comes from an abbreviation of the Latin word “recipe” meaning “take”, as in the command form of the verb recipere, which means “to hold or contain.” It doesn’t come from a joining of the letters R and x, but rather the slashed line through the “R” was […]

The stately Classical background of Paris’ Panthéon has been the perfect location to house the invention of 19th-century physicist Léon Foucault: a massive pendulum made of a 62-lb brass-coated led bob, suspended from the Panthéon’s central dome by a 220-foot wire. Foucault debuted his pendulum in 1851, and although the original was damaged in 1995,

Late 18th-century Georgian Britain had such fascinating trends. An age of Enlightenment, it brought forth people who were in love with science and anything that sounded “science-y”, even when the actual science was missing. And, no surprise, interest peaked when said pseudo-science trend dealt with sex. This brings me to one James Graham (1745-1794), a

We all know the man on the right — that’s Albert Einstein, the most famous scientist of the 20th century. But to his left is another important scientist, Kurt Gödel, a mathematician so brilliant that Einstein said that he used to come to the Institute of Advanced Study at Princeton just “to have the privilege

This post is about a mathematical puzzle and a French astronomer-mathematician who tried to solve it: the Three-Body Problem, and Nicole-Reine Lepaute, an aristocratic woman working in Enlightenment-Era France. (See images one and two.) Practically as soon as Isaac Newton developed his ideas about gravity, he also realized that, while he could predict the orbits

Often revolutions are only recognized as such in the wake of their transformations. This was the case for the massive shift in human culture in accepting the fact that the earth orbits the sun rather than the other way around. Between the heliocentric model of Nicolaus Copernicus (d. 1543) and the Papacy’s condemnation of Galileo

This photo shows a Carthusian monk mixing ingredients for the liqueur known as “Chartreuse,” a beverage so famous that it gave its name to a color. The monks have been producing this drink for centuries. The Carthusian order has been consistently strict since their founding in the late eleventh century. The monks have prayed and

The excavations of the Ancient Maya world have continued to reveal surprises, and in 2020 two fascinating stories about urban water supply made headlines. Both were about the city of Tikal (known as Yax Mutal among the ancient Maya), but one was much sadder than the other. Tikal was an epicenter of power and was

“We in the West are the first generation in human history in which the mass of the population has to deliberately exercise to be healthy.” — so wrote Jeremiah “Jerry” Morris towards the end of his 99-year life of remarkable scholarship about the effects of disease and physical movement. Or really, the lack of physical

Here you are looking at the compound microscope developed by Robert Hooke (d 1703), a Renaissance scientist more famous for dabbling in academic fields as disparate as physics and palaeontology than a particular discovery. Nevertheless, his microscope allowed him to illustrate things he included in _Micrographia_, which utterly captivated his British audience. Samuel Pepys the

Using gas chromatography and mass spectrometry, scientists were for the first time able to figure out the source of an ingredient in an actual Ancient Roman perfume: and it was patchouli. In 2019, archaeologists digging in the burial grounds of the once-active Roman site in Spain called Carmina discovered an oval lead case holding a

This Hindu Goddess has been around for a long time: I introduce to you all the deity Sheetala (also Shitala). In English, her name means “the cooling one,” and she is a mother goddess protector from smallpox and childhood illnesses — except for the times when she becomes the embodiment of disease and annihilates those

“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:

This reconstruction of a Homo heidelbergensis (600,000-300,000 years ago) reminds us that we H. sapiens are not the only genus of our kind to have walked the earth, and our Homo ancestors, like us, shared an interesting quality: we lack hair. Of course, we have some hair — our heads and genitals, and many of

The origin of mushrooms is ancient — in fact, a 2020 scientific paper reported the discovery of fossilized fungi found in the Democratic Republic of Congo dating from 715 to 810 million years ago! Yet there is much scientists still do not understand about these fruiting bodies of the Earth’s mycelium layer (a network of

“Snake Oil” earned the connotation of being a huckster’s fake medical treatment in the early 20th century thanks largely to the efforts of one Clarke Stanley, whose infamous product is featured here. However, the actual origins of snake oil as a medicinal product have a different and more legitimate background in Chinese traditional medicine. Clarke

This is the July 31, 1978 cover of Time magazine, heralding the origin of in vitro fertilization which had been made possible in the previous years with the efforts of Robert Edwards, Patrick Steptoe, Barry Bavister, and Jean Purdy. Purdy had been the one to actually create the first human embryo through IVF, and held the
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
