    Aug 13 2025
    What do the world's loneliest whale, a black hole, and twenty-three people doing Tae Bo all have in common? In 2011, a skyscraper in South Korea began to shake uncontrollably without warning and was immediately evacuated. Was it an earthquake? An attack? No one seemed quite sure. The actual cause emerged later and is utterly fascinating: Twenty-three middle-aged folks were having a Tae Bo fitness class in the office gym on the twelfth floor. Their beats had inadvertently matched the building's natural frequency, and this coincidence--harnessing a basic principle of physics--caused the building to shake at an alarming rate for ten minutes. Frequency is all around us, but little understood. Musician, composer, TV presenter, and educator Richard Mainwaring uses the concept of the Infinite Piano to reveal the extraordinary world of frequency in a multitude of arenas--from medicine to religion to the environment to the paranormal--through the universality of music and a range of memorable human (and animal) stories laced with dry humor. Whether you're science curious, musically inclined, or just want to know what a Szechuan pepper has to do with physics, What the Ear Hears (and Doesn't): Inside the Extraordinary Everyday World of Frequency (Sourcebooks, 2022) is an immensely enjoyable read filled with "did you know?" trivia you'll love to share with friends.

    Emilio Elizalde, "The True Story of Modern Cosmology: Origins, Main Actors and Breakthroughs" (Springer, 2021)
    Aug 8 2025
    This book tells the story of how, over the past century, dedicated observers and pioneering scientists achieved our current understanding of the universe. It was in antiquity that humankind first attempted to explain the universe often with the help of myths and legends. This book, however, focuses on the time when cosmology finally became a true science. As the reader will learn, this was a slow process, extending over a large part of the 20th century and involving many astronomers, cosmologists and theoretical physicists. The book explains how empirical astronomical data (e.g., Leavitt, Slipher and Hubble) were reconciled with Einstein's general relativity; a challenge which finally led Friedmann, De Sitter and Lemaître, and eventually Einstein himself, to a consistent understanding of the observational results. The reader will realize the extraordinary implications of these achievements and how deeply they changed our vision of the cosmos: From being small, static, immutable and eternal, it became vast and dynamical - originating from (almost) nothing, and yet now, nearly 14 billion years later, undergoing accelerated expansion. But, as always happens, as well as precious knowledge, new mysteries have also been created where previously absolute certainty had reigned. Learn more about your ad choices.

    David J. Helfand, "The Universal Timekeepers: Reconstructing History Atom by Atom" (Columbia UP, 2023)
    Aug 7 2025
    Atoms are unfathomably tiny. It takes fifteen million trillion of them to make up a single poppy seed—give or take a few billion. And there’s hardly anything to them: atoms are more than 99.9999999999 percent empty space. Yet scientists have learned to count these slivers of near nothingness with precision and to peer into their internal states. In looking so closely, we have learned that atoms, because of their inimitable signatures and imperturbable internal clocks, are little archives holding the secrets of the past.David J. Helfand reconstructs the history of the universe—back to its first microsecond 13.8 billion years ago—with the help of atoms. He shows how, by using detectors and reactors, microscopes and telescopes, we can decode the tales these infinitesimal particles tell, answering questions such as: Is a medieval illustrated prayer book real or forged? How did maize cultivation spread from the highlands of central Mexico to New England? What was Earth’s climate like before humans emerged? Where can we find clues to identify the culprit in the demise of the dinosaurs? When did our planet and solar system form? Can we trace the births of atoms in the cores of massive stars or even glimpse the origins of the universe itself?A lively and inviting introduction to the building blocks of everything we know, The Universal Timekeepers demonstrates the power of science to unveil the mysteries of unreachably remote times and places.

  • Robyn Arianrhod, "Vector: A Surprising Story of Space, Time, and Mathematical Transformation" (U of Chicago Press, 2024)

    Robyn Arianrhod, "Vector: A Surprising Story of Space, Time, and Mathematical Transformation" (U of Chicago Press, 2024)
    Jul 25 2025
    A celebration of the seemingly simple idea that allowed us to imagine the world in new dimensions--sparking both controversy and discovery. The stars of this book, vectors and tensors, are unlikely celebrities. If you ever took a physics course, the word "vector" might remind you of the mathematics needed to determine forces on an amusement park ride, a turbine, or a projectile. You might also remember that a vector is a quantity that has magnitude and (this is the key) direction. In fact, vectors are examples of tensors, which can represent even more data. It sounds simple enough--and yet, as award-winning science writer Robyn Arianrhod shows in this riveting story, the idea of a single symbol expressing more than one thing at once was millennia in the making. And without that idea, we wouldn't have such a deep understanding of our world. Vector and tensor calculus offers an elegant language for expressing the way things behave in space and time, and Arianrhod shows how this enabled physicists and mathematicians to think in a brand-new way. These include James Clerk Maxwell when he ushered in the wireless electromagnetic age; Einstein when he predicted the curving of space-time and the existence of gravitational waves; Paul Dirac, when he created quantum field theory; and Emmy Noether, when she connected mathematical symmetry and the conservation of energy. For it turned out that it's not just physical quantities and dimensions that vectors and tensors can represent, but other dimensions and other kinds of information, too. This is why physicists and mathematicians can speak of four-dimensional space-time and other higher-dimensional "spaces," and why you're likely relying on vectors or tensors whenever you use digital applications such as search engines, GPS, or your mobile phone. In exploring the evolution of vectors and tensors--and introducing the fascinating people who gave them to us--Arianrhod takes readers on an extraordinary, five-thousand-year journey through the human imagination. She shows the genius required to reimagine the world--and how a clever mathematical construct can dramatically change discovery's direction. Learn more about your ad choices.

    Paul Sen, "Einstein's Fridge: How the Difference Between Hot and Cold Explains the Universe" (Scribner, 2021)
    Jul 17 2025
    Einstein's Fridge: How the Difference Between Hot and Cold Explains the Universe (Scribner, 2021) tells the incredible epic story of the scientists who, over two centuries, harnessed the power of heat and ice and formulated a theory essential to comprehending our universe. “Although thermodynamics has been studied for hundreds of years…few nonscientists appreciate how its principles have shaped the modern world” (Scientific American). Thermodynamics—the branch of physics that deals with energy and entropy—governs everything from the behavior of living cells to the black hole at the center of our galaxy. Not only that, but thermodynamics explains why we must eat and breathe, how lights turn on, the limits of computing, and how the universe will end.The brilliant people who decoded its laws came from every branch of the sciences; they were engineers, physicists, chemists, biologists, cosmologists, and mathematicians. From French military engineer and physicist Sadi Carnot to Lord Kelvin, James Joule, Albert Einstein, Emmy Noether, Alan Turing, and Stephen Hawking, author Paul Sen introduces us to all of the players who passed the baton of scientific progress through time and across nations. Incredibly driven and idealistic, these brave pioneers performed groundbreaking work often in the face of torment and tragedy. Their discoveries helped create the modern world and transformed every branch of science, from biology to cosmology.“Elegantly written and engaging” (Financial Times), Einstein’s Fridge brings to life one of the most important scientific revolutions of all time and captures the thrill of discovery and the power of scientific progress to shape the course of history.

    Liam Graham, "Molecular Storms: The Physics of Stars, Cells and the Origin of Life" (Springer Nature, 2023)
    Jun 22 2025
    Why is the universe the way it is? Wherever we look, we find ordered structures: from stars to planets to living cells. Molecular Storms: The Physics of Stars, Cells and the Origin of Life (Springer Nature, 2023) shows that the same driving force is behind structure everywhere: the incessant random motion of the components of matter. Physicists call it thermal noise. Let's call it the molecular storm. This storm drives the fusion reactions that make stars shine. It drives whirlpools and currents in atmospheres and oceans. It spins and distorts molecules until they are in the right orientation to react and form new substances. In living cells, it drives proteins to fold and molecules to self-assemble. It is behind every detail of the astonishing molecular machines that control cellular processes. Using cutting-edge research, "Molecular Storms" takes us on a dazzling journey from the early universe to the interior of the smallest living things. There, in a nanoscale world of biological devices, it explains the physics behind the chemical system which we call Life. Whether you're someone with a general interest in science or a student looking to add context to your studies, this book is for you. "Molecular Storms" is an accessible and captivating read that will deepen your appreciation of the power of science to explain the world. Learn more about your ad choices.

  • Sharon Udasin and Rachel Frazin, "Poisoning the Well: How Forever Chemicals Contaminated America" (Island Press, 2025)

    Sharon Udasin and Rachel Frazin, "Poisoning the Well: How Forever Chemicals Contaminated America" (Island Press, 2025)
    May 2 2025
    This is the shocking true-life story of how PFAS—a set of toxic chemicals most people have never heard of—poisoned the entire country. Based on original, shoe-leather reporting in four highly contaminated towns and damning documents from the polluters’ own files, Poisoning the Well: How Forever Chemicals Contaminated America (Island Press, 2025) traces an ugly history of corporate greed and devastation of human lives. We learn that PFAS, the ‘forever chemicals’ found in everyday products, from cooking pans to mascara, are coursing through the veins of 97% of Americans. We witness the pain of families who lost sisters and daughters, cousins and neighbors, after PFAS leached into their drinking water. We discover evidence that the makers of forever chemicals may have known for decades about the deadly risks of their products—because their own scientists have been documenting these dangers since the 1960s. And we see the failure of our government, time after time, to provide basic protections to its citizens. It is impossible to read this searing exposé without being infuriated by the recklessness of corporate America. But readers will also be awed by the spirit of ordinary people who, while fighting for their own lives, took it upon themselves to fix a broken regulatory system. Heart-wrenching and maddening, stirring and uplifting, Poisoning the Well offers a unique window into the worst and best of human nature. It is essential reading for anyone concerned about the unfettered power of industry and the invisible threat it poses to the health of the nation—and to each of us. Sharon Udasin is a reporter for The Hill, covering U.S. West climate & policy from her home base in Boulder, Colorado. She was a Ted Scripps Fellow in Environmental Journalism at the University of Colorado Boulder and has also reported for The Jerusalem Post and The New York Jewish Week.

  • Scientists Cooperate while Humanists Ruminate (EF, JP)

    Scientists Cooperate while Humanists Ruminate (EF, JP)
    Apr 17 2025
    Back in 2021, John and Elizabeth sat down with Brandeis string theorist Albion Lawrence to discuss cooperation versus solitary study across disciplines. They sink their teeth into the question, “Why do scientists seem to do collaboration and teamwork better than other kinds of scholars and academics?” The conversation ranges from the merits of collective biography to the influence of place and geographic location in scientific collaboration to mountaineering traditions in the sciences. As a Recallable Book, Elizabeth champions The People of Puerto Rico, an experiment in ethnography of a nation (in this case under colonial rule) from 1956, including a chapter by Robert Manners, founding chair of the Brandeis Department of Anthropology. Albion sings the praises of a collective biography of the Art Ensemble of Chicago, A Message to Our Folks. But John stays true to his Victorianist roots by praising the contrasting images of the withered humanist Casaubon and the dashing young scientist Lydgate in George Eliot’s own take on collective biography, Middlemarch. Discussed in this episode: Richard Rhodes Making of the Atomic Bomb Ann Finkbeiner, The Jasons: The Secret History of Science’s Postwar Elite James Gleick, The Information Jon Gertner, The Idea Factory: Bell Labs and the Great Age of American Innovation Black Hole photographs win giant prize Adam Jaffe, “Geographic Localization of Knowledge Spillovers as Evidenced by Patent Citations“ Jamie Cohen-Cole, The Open Mind Julian Steward et al., The People of Puerto Rico Paul Steinbeck, Message to Our Folks Jenny Uglow, Lunar Men George Eliot, Middlemarch Listen to and Read the episode here.
