What if, every time you wanted to write down 1,000,000, you had to draw a picture of a god? And what if that number were the biggest you had a symbol for? If you were doing math in ancient Egypt, those were the rules: anything bigger broke math. As mathematician Richard Elwes shows i n Huge Numbers: A Story of Counting Ambitiously, from 4 1/2 to Fish 7 ( Basic Books, 2026) this is the strange story of math. Even today, writing down some numbers is beyond us: try it with all the zeroes in a googo...

In the well-trod history of the Roman Empire, a pivotal moment has long gone unnoticed: It was in ancient Rome that medical men first set their sights on childbirth, the traditional domain of female midwives. Taking us to the dawn of Western obstetrics, A Womb of One's Own: Lost Histories of Childbirth in Ancient Rome (U California Press, 2026) by Dr. Tara Mulder offers a feminist account of how, against a long tradition of midwifery, male doctors began claiming authority in reproductive matters...

The Museum of Imaginary Musical Instruments (Reaktion, 2026) by Dr. Deirdre Loughridge & Dr. Thomas Patteson is a guided tour through centuries of instruments that never existed. From ancient myths to futuristic media, these imagined devices appear in literature, theory, video games and art, at times echoing real instruments, other times pushing far beyond the bounds of technology. This book presents a wide-ranging collection of such creations, showing how they reflect changing ideas about s...

In the thirteenth-century Mediterranean, commerce transformed as merchants shifted from Roman to Indo-Arabic numerals—an alternative that better facilitated complex calculations. It has long been known that this transition stemmed from Europe’s increasing exchanges with India, Persia, and the Arabic world. Yet much remains to be understood about how Indo-Arabic numerals—and the practical arithmetic they enabled—actually spread across Europe. As Dr. Raffaele Danna shows in The Craft of Indo-Arabi...

Jim Downs’ most recent book is Maladies of Empire: How Colonialism, Slavery, and War Transformed Medicine. Professor Downs is the Gilder Lehrman-National Endowment for the Humanities Professor of Civil War Era Studies and History at Gettysburg College.

Flowering currant, ivy, Portuguese laurel, and woad might all have grown in a medieval garden, but it would have taken special expertise to extract and create rich blue and purple pigments from them. Humans have been extracting dyes and inks from natural materials for millennia, and the practice was firmly established during the medieval era, recorded in manuscripts that survive today. Gold from Newton's Apple Tree: Historical Recipes for Natural Inks, Paints, and Dyes (Princeton UP, 2026) by Na...

The South American coca plant was established in 19th-century Britain as a medical product before it became a globally restricted drug. Drawing on botanical, economic, pharmaceutical, social, and political perspectives, in Coca and the Victorians: From Botanical Curiosity to Regulated Drug, 1835–1912 (Transcript Publishing, 2025), Dr. Kim Embrey analyses how the use and perception of coca changed as it was transferred to Europe. In a process of cultural dissimilation, coca was not simply adopted...

Naming new discoveries is central to science, and for centuries, Latin dominated this process. The resulting terminology still shapes modern science, yet the influences behind its creation have remained largely unexplored. Naming New Things and Concepts in Early Modern Science: The Case of Natural History (Cambridge University Press, 2026) by Dr. Dominik Berrens is the first comprehensive exploration of how modern scientific terminology took shape during the early modern period. Far from being t...

We often think of medieval medicine as strange, unhygienic and unscientific, but The Medieval Guide to Healthy Living (Reaktion, 2026) by Dr. Katherine Harvey reveals a far richer story. Long before modern wellness trends, people in the Middle Ages were actively thinking about how to live well. They followed detailed health regimens, balanced diet with exercise, considered the effects of emotions and sought to avoid illness through environmental awareness and routine care. This book sheds light ...

Mintz reframes health anxiety not as a pathology but as a site of creative potential – exploring hypochondria as a form of communication, a reorientation to time, a convergence of personal and communal identity, a declaration of bodymind needs and an embrace of ageing’s transformations.

In Gems and the New Science: Matter and Value in the Scientific Revolution (U Chicago Press, 2026), Dr. Michael Bycroft argues that gems were connected to major developments in the “new science” between the sixteenth and nineteenth centuries. As he explains, precious and semiprecious stones were at the center of dramatic shifts in natural knowledge in early modern Europe. They were used to investigate luminescence, electricity, combustion, chemical composition, and more. They were collected by n...

In Heart of Science: A Philosophy of Scientific Inquiry (University of Chicago Press, 2026), philosopher Jacob Stegenga breaks with the most dominant epistemologies of science to argue that in judging scientific activity, we should focus on its justification, not the achievement of truth or knowledge. Yet, Stegenga argues, the aim of science goes far beyond justification and is, instead, a special kind of truth—common knowledge, a broadly shared and mutually justified scientific finding.

From the beginning of Galileo’s career, well before the publication of the Sidereus Nuncius, his contemporaries took pains to shape his reputation and fame. They were fully aware that their efforts would shape the course of his career; they also knew that they would profit from helping him.

Eyeglasses have become so commonplace we hardly think about them—unless we can’t find them. Yet glasses have been controversial throughout history. Roger Bacon pioneered using lenses to see and then spent a decade in a medieval prison for advocating that he could fix" God’s creations by improving our eyesight. Even today, people take off their glasses before having their picture taken, despite how necessary they are. A Four-Eyed World: How Glasses Changed the Way We See (Bloomsbury, 2026) is the...

Today I talked to John L. Rudolph about his book Why We Teach Science (and Why We Should) (Oxford UP, 2023). Few people question the importance of science education in American schooling. The public readily accepts that it is the key to economic growth through innovation, develops the ability to reason more effectively, and enables us to solve the everyday problems we encounter through knowing how the world works. Good science teaching results in all these benefits and more -- or so we think. Bu...
