New Books in the History of Science

Dropping the atomic bombs on Japan during World War II was, arguably, the most controversial decision of the 20th century. The responsibility for that “decision” has logically fallen on US President Harry S. Truman. But in The Most Awful Responsibility: Truman and the Secret Struggle for Control of the Atomic Age (Harper, 2025), Alex Wellerstein argues that Truman's actual decision wasn’t what everyone thinks it was.

The conventional narrative is that American leaders had a choice: Invade Japan, which would have cost millions of Allied and Japanese lives, or instead, use the atom bomb in the hope of convincing Japan to surrender. Truman, the story goes, carefully weighed the pros and cons before deciding that the atomic bomb would be used against Japanese cities, as the lesser of two evils.

But nuclear historian Alex Wellerstein argues that is not what happened.

Not only did Truman not take part in the decision to use the bomb, but the one major decision that he did make was a very different one — one that he himself did not fully understand until after the atomic bomb was used. The weight of that decision, and that misunderstanding, became the major reason that atomic bombs have not been used again since World War II.

Based on a close reading of the historical record, The Most Awful Responsibility shows that, despite his reputation as an ardent defender of the atomic bomb, Truman:

Wanted to avoid the “murder” and “slaughter” of innocent civilians

Believed that the atomic bomb should never be used again

Hoped that nuclear weapons would be outlawed in his lifetime

Wellerstein makes a startling case that Truman was possibly the most anti-nuclear American president of the twentieth century, but his ambitions were strongly constrained by the domestic and international politics of the postwar world and the early Cold War. This book is a must-read for all who want to truly understand not only why the bomb was dropped on Japan but also why it has not been used since.

As a graduate student at MIT, Steve Ramirez successfully created false memories in the lab. Now, as a neuroscientist working at the frontiers of brain science, he foresees a future where we can replace our negative memories with positive ones. In How to Change a Memory, Ramirez draws on his own memories--of friendship, family, loss, and recovery--to reveal how memory can be turned on and off like a switch, edited, and even constructed from nothing.

A future in which we can change our memories of the past may seem improbable, but in fact, the everyday act of remembering is one of transformation. Intentionally editing memory to improve our lives takes advantage of the brain's natural capacity for change.

In How to Change a Memory: One Neuroscientist’s Quest to Alter the Past (Princeton UP, 2025), Ramirez explores how scientists discovered that memories are fluid--they change over time, can be erased, reactivated, and even falsely implanted in the lab. Reflecting on his own path as a scientist, he examines how memory manipulation shapes our imagination and sense of self. If we can erase a deeply traumatic memory, would it change who we are? And what would that change mean anyway? Throughout, Ramirez carefully considers the ethics of artificially controlling memory, exploring how we might use this tool responsibly--for both personal healing and the greater good.

A masterful blend of memoir and cutting-edge science, How to Change a Memory explores how neuroscience has reached a critical juncture, where scientists can see the potential of memory manipulation to help people suffering from the debilitating effects of PTSD, anxiety, Alzheimer's, addiction, and a host of other neurological and behavioral disorders.

Steve Ramirez has been featured on CNN, NPR, and the BBC and in leading publications such as The New York Times, National Geographic, Wired, Forbes, The Guardian, The Economist, and Nature. An award-winning neuroscientist who has given TED talks on his groundbreaking work on memory manipulation, he is associate professor of psychological and brain sciences at Boston University.

Clare Griffin's book Mixing Medicines: The Global Drug Trade and Early Modern Russia (McGill-Queen's UP, 2022) introduces the reader to the dynamic and complex world of early modern Russian medical drugs, from the enthusiasm for newly imported American botanicals to the disgust at Western European medicines made from human corpses.
Based on a unique set of previously unused sources, this book is the first study of how the Russian Empire took part in the early modern global trade in medical drugs. The extensive and detailed records kept by the Moscow court show how ingredients produced elsewhere and passed through the massive, long-distance trade network of the early modern world were finally consumed. Looking at medicine as materia medica gives us a different perspective than when looking at practitioners, texts, and ideas.

Why did Isaac Newton read books on chiromancy, the occult science of hand reading that revealed the secrets of the soul? Why did Charles Darwin claim that the hand gave humans dominion over all other species? Why did psychoanalyst Charlotte Wolff climb into the primate cages of the London Zoo, taking hundreds of delicate palm prints? Why did Francis Galton, the father of fingerprinting, take palm prints too? And why did world-leading geneticists study the geometry of palm lines in their search for the secrets of chromosomal syndromes?

Decoding the Hand: A History of Science, Medicine, and Magic (University of Chicago, 2025) is an astounding history of magic, medicine, and science, of an enduring search for how our bodily surfaces might reveal an inner self—a soul, a character, an identity. From sixteenth-century occult physicians influenced by the Kabbalah to twentieth-century geneticists, and from criminologists to eugenicists, award-winning historian Dr. Alison Bashford takes us on a remarkable journey into the strange world of hand readers, revealing how signs on the hand—its shape, lines, marks, and patterns—have been elaborately decoded over the centuries. Sometimes learned, sometimes outrageously deceptive, sometimes earnest, and, more often than we ever expected, medically and scientifically trained, these palm readers of the past prove to be essential links in the human quest to peer into bodies, souls, minds, and selves. Not only for fortune-telling palmists were the future and the past, health, and character laid bare in the hand, but for other experts in bodies and minds as well: anatomists, psychiatrists, embryologists, primatologists, evolutionary biologists, geneticists, and more.

Drawing telling parallels between the divination promised by palmistry and the appeal to self-knowledge offered by modern genetic testing, Decoding the Hand also makes clear that palm-reading is far from a relic or simple charlatanism. Dr. Bashford’s sagacious history of human hands touching and connecting opens wide the essential human pursuit of what lies within and beyond.

This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

The Arrival of the Fittest: Biology’s Imaginary Futures, 1900–1935 by Jim Endersby

In the early twentieth century, varied audiences took biology out of the hands of specialists and transformed it into mass culture, transforming our understanding of heredity in the process.In the early twentieth century communities made creative use of the new theories of heredity in circulation at the time, including the now largely forgotten mutation theory of Hugo de Vries. Science fiction writers, socialists, feminists, and utopians are among those who seized on the amazing possibilities of rapid and potentially controllable evolution. De Vries’s highly respected scientific theory only briefly captured the attention of the scientific community, but its many fans appropriated it for their own wildly imaginative ends. Writers from H.G. Wells and Edith Wharton to Charlotte Perkins Gilman, J.B.S. Haldane, and Aldous Huxley created a new kind of imaginary future, which Jim Endersby calls the biotopia. It took the ambiguous possibilities of biology—utopian and dystopian—and reimagined them in ways that still influence the public’s understanding of the life sciences. The Arrival of the Fittest recovers the fascinating, long-forgotten origins of ideas that have informed works of fiction from Brave New World to the X-Men movies, all while reflecting on the lessons—positive and negative—that this period might offer us.
