Scientists are enabling us to save lives and hopefully prevent disaster in this COVID-19 pandemic — and coming up with big solutions to health problems is one of the main reasons their profession is so valuable. But for me there is another equally praiseworthy aspect: their contributions to unveiling the forces that shape our universe. […]

In the Medieval and Early Modern periods, natural science blended with occult studies, and this is why the modern subject of chemistry arose out of the ancient practice of alchemy. This intermixing of the mysterious and the concrete can be illustrated by the concept of a Diana’s Tree.Diana was the Ancient Roman Goddess of the

This Medieval map shows the northern and southern hemispheres, with the constellations drawn to represent the stars’ positions. Although it is likely ordinary Europeans could point out different patterns in the sky, you had to have elite training to be able to pass yourself off as a real star-gazer: it was totally normal for people

As the days of quarantine add up, many of us have expressed a strange sense of time becoming blurred — the hours we used to divide with our old routines have been upended, and our unchanging surroundings can sometimes make the feeling of time feel less progressive. In fact, of course, the external physical world

Get ready to geek out here, because I am going to sing praises for the ways molecular chemical analysis is helping historians understand more clearly how people saw and created art in Medieval Europe. This first slide here is part of a cover page for a new paper published in _Scientific Advances_ which shows fabric

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

May I introduce you to Min Chiu Li, a Chinese-American scientist to whom many of us owe our lives or the lives of loved ones? In the 1950s, Li figured out a critical aspect about how the disease cancer works, leading to the successful employment of chemotherapy.Min Chiu Li came to the United States to

This week we are looking at famous cases of poisoning in history. We begin with the murder of Georgi Markov, who was killed by a small pellet of ricin aimed from an assassin’s weaponized umbrella.Georgi Markov was a writer, and had dissented from the authoritarian government of his homeland in Bulgaria. Using his talent as

Here is a member of the Selous Scouts, a group of special military forces active in the former African state of Rhodesia from 1973-1980. During the Rhodesian Bush War of decolonisation, the Selous Scouts represented the minority white government which struggled to keep power as the black majority fought for an independent state. The Selous

In our final post in this week’s series on poisonings in history, I am featuring Alan Turing’s death by cyanide. Turing was, of course, the famous father of theoretical computer science, paving the way for Artificial Intelligence in his development of the “Turing machine,” a mathematical model of computation that enabled much of what we

This is Marie-Claire King (born 1946), and just reading about her accomplishments makes me tired. Besides earning her Ph.D. from UC Berkeley, she has six other honorary doctorates in science from the most prestigious universities in the world. From her work in discovering the genetic foundations of breast cancer, schizophrenia, and hearing loss, to her

Charles Darwin’s idea of Natural Selection as the key driver of evolution has been demonstrated many times over. However, in the century and a half since his lifetime, scientists have added onto his theories as various scientific discoveries have been made. Perhaps no one has reframed the picture of Darwinian evolution as much as the

The global situation right now is dominated by discussion of COVID-19, as well as the Herculean attempts to create a vaccine for the disease. And as reports of the Phase III trials start to come in, we can look at this photo — a scientist’s laboratory from the early 20th century, cluttered and filthy. Rotting

The two pictures shown here accompanied two of the most important “aha!” moments in history. The first is “Photo 51,” taken under the laboratory research of Rosalind Franklin. It shows an X-ray diffraction pattern of DNA, and Franklin, Watson, and Crick used it to figure out the molecular structure of life itself.The second is a

The Scientific Revolution that developed in Europe did not always lead to the embracing of rationality. This engraving by William Hogarth from 1751 is a case in point. You see in this image a grand display of the dissection of a corpse at the hands of professional anatomists. Yet even though the endeavour might have

Language changes slowly, words accruing and altering their meanings and pronunciations over the course of decades and centuries. But sometimes we find sudden movements of seismic proportion, particularly with the history of written languages. Thus is the case with the invention of Braille, the eponymous system named for its creator, Louis Braille. And just in

Osteotome, anyone? You are looking at a reproduction of medical tools used in Ancient Roman surgery during the first century to cut into human bones. Many Ancient Roman medical instruments were made out of copper or copper alloys like brass (copper and zinc) or bronze (copper and tin). Educated physicians in Ancient Rome believed that
