There’s nothing more vital to survival than water. “Water water everywhere, and not a drop to drink!”, said the Ancient Mariner, in the poem by Samuel Taylor Coleridge. Besides widespread water shortage, too much of America’s water is undrinkable. From big cities and suburbs to the rural heartland, chemicals linked to cancer, heart disease, obesity, birth defects, and lowered IQ routinely spill from our taps. The tragedy is that existing technologies could launch a new age of clean, healthy, and...

Anne Bogart's The Art of Resonance (Methuen Drama, 2021) locates the essence of theatre in the experience of resonant vibration among performers and between performers and audience members. The point of art, Bogart argues, is not to express oneself, but rather to create the conditions for "re-sounding," a process that requires both fully engaged performers and a fully engaged audience. Bogart draws on examples from music to physics to neuroscience in a book of essays that is animated by the same...

Though trained as a medical doctor, chemist Harvey Wiley spent most of his professional life advocating for "pure food"—food free of both adulterants and preservatives. A strong proponent of the Pure Food and Drug Act of 1906, still the basis of food safety legislation in the United States, Wiley gained fame for what became known as the Poison Squad experiments—a series of tests in which, to learn more about the effects of various chemicals on the human body, Wiley's own employees at the Departm...

The Problems of Physics, Reconsidered is based on an in-depth filmed conversation between Howard Burton and Physics Nobel Laureate Tony Leggett. The basis of this conversation is Tony Leggett’s book The Problems of Physics and further explores the insightful plain-speaking itemization that he developed of the physics landscape according to four basic categories—the very small (particle physics), the very large (cosmology), the very complex (condensed matter physics) and the very unclear (foundat...

There is a vast class of things that science has so far almost entirely neglected. They are central to the understanding of physical reality both at an everyday level and at the level of the most fundamental phenomena in physics, yet have traditionally been assumed to be impossible to incorporate into fundamental scientific explanations. They are facts not about what is (the actual) but about what could be (counterfactuals). According to physicist Chiara Marletto, laws about things being possibl...

Quantum mechanics is full of weird findings – for example, that systems widely separated can somehow still be correlated, and that a system may be in two different possible states at the same time. Entanglement and superposition, among other phenomena, have prompted debate since the inception of QM about how, exactly, we should understand what it tells us about reality. In The World in the Wave Function (Oxford UP, 2021), Alyssa Ney defends wave function realism, the claim that the basic represe...

Things in life tend to fall apart. Cars break down. Buildings fall into disrepair. Personal items deteriorate. Yet today’s researchers are exploiting newly understood properties of matter to program materials that physically sense, adapt, and fall together instead of apart. These materials open new directions for industrial innovation and challenge us to rethink the way we build and collaborate with our environment. Things Fall Together: A Guide to the New Materials Revolution (Princeton UP, 202...

Given the obsession with information and secrecy in today’s world, it can be difficult to imagine a time when governments held few secrets and worried little about what information was public knowledge. In Restricted Data: The History of Nuclear Secrecy in the United States (University of Chicago Press, 2021), Alex Wellerstein chronicles how much of this change can be traced to the development of atomic weapons in the 1940s and the efforts both then and since to restrict the details about them. ...

Everyone has heard of the term "pseudoscience", typically used to describe something that looks like science, but is somehow false, misleading, or unproven. Many would be able to agree on a list of things that fall under its umbrella-- astrology, phrenology, UFOlogy, creationism, and eugenics might come to mind. But defining what makes these fields "pseudo" is a far more complex issue. It has proved impossible to come up with a simple criterion that enables us to differentiate pseudoscience from...

Chemistry is not just about microscopic atoms doing inscrutable things; it is the process that makes flowers and galaxies. We rely on it for bread-baking, vegetable-growing, and producing the materials of daily life. In stunning images and illuminating text, this book captures chemistry as it unfolds. Using such techniques as microphotography, time-lapse photography, and infrared thermal imaging, The Beauty of Chemistry: Art, Wonder, and Science (MIT Press, 2021) shows us how chemistry underpins...

Few astronomers in the 20th century did as much to expand our understanding of the universe as Vera Rubin. To tell her remarkable story in their biography Vera Rubin: A Life (Belknap Press, 2021), authors Jacqueline and Simon Mitton describe both the range of her accomplishments as well as the barriers she overcame in order to achieve them. As they explain, Rubin was drawn early to the study of the stars, determining early in her life that she wanted to be an astronomer. To become one she had to...

What is life? For generations, scientists have struggled to make sense of this fundamental question, for life really does look like magic: even a humble bacterium accomplishes things so dazzling that no human engineer can match it. Huge advances in molecular biology over the past few decades have served only to deepen the mystery. In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it...

Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischievously materialized in the scientific imagination itself. Scientists began to employ hypothetical beings to perform certain roles in thought experiments—experiments that can only be done in the imagination—and these impish assistants helped scientists achieve major breakthroughs that pushed for...

In 1618, on the eve of the Thirty Years’ War, the German alchemist and physician Michael Maier published Atalanta fugiens, an intriguing and complex musical alchemical emblem book designed to engage the ear, eye, and intellect. The book unfolds as a series of fifty emblems, each of which contains an accompanying "fugue" music scored for three voices. Historians of alchemy have long understood this virtuoso work as an ambitious demonstration of the art’s literary potential and of the possibilitie...

Since the dawn of the industrial age, we have unleashed a bewildering number of potentially harmful chemicals. But out of this vast array, how do we identify the actual threats? What does it take to prove that a certain chemical causes cancer? How do we translate academic knowledge of the toxic effects of particular substances into understanding real-world health consequences? The science that answers these questions is toxicology. In The Alchemy of Disease: How Chemicals and Toxins Cause Cancer...

“How did life begin? Most things in the universe aren't alive, and yet if you trace the evolutionary history of plants and animals back far enough, you will find that, at some point, neither were we. Scientists have wrestled with the problem through the ages, and yet they still don’t agree on what kind of answer they are even looking for. But in 2013, at just 30 years old, physicist Jeremy England published a paper that has utterly upended the ongoing study of life’s origins. In Every Life is on...
