Most of us know something about the grand theories of physics that transformed our views of the universe at the start of the twentieth century: quantum mechanics and general relativity. But we are much less familiar with the brilliant theories that make up the backbone of the digital revolution. In Beautiful Math: The Surprisingly Simple Ideas behind the Digital Revolution in How We Live, Work, and Communicate (MIT Press, 2024) Chris Bernhardt explores the mathematics at the very heart of the information age. He asks questions such as: What is information? What advantages does digital information have over analog? How do we convert analog signals into digital ones? What is an algorithm? What is a universal computer? And how can a machine learn?The four major themes of Beautiful Math are information, communication, computation, and learning. Bernhardt typically starts with a simple mathematical model of an important concept, then reveals a deep underlying structure connecting concepts from what, at first, appear to be unrelated areas. His goal is to present the concepts using the least amount of mathematics, but nothing is oversimplified. Along the way, Bernhardt also discusses alphabets, the telegraph, and the analog revolution; information theory; redundancy and compression; errors and noise; encryption; how analog information is converted into digital information; algorithms; and, finally, neural networks. Historical anecdotes are included to give a sense of the technology at that time, its impact, and the problems that needed to be solved.

Taking its readers by the hand, regardless of their math background, Beautiful Math is a fascinating journey through the mathematical ideas that undergird our everyday digital interactions.

Chris Miller, Tufts Professor and author, explains how semiconductors—those tiny chips inside your phone, car, and coffee maker—have become the most critical technology in the world. Today’s global economy, military power, and AI breakthroughs all hinge on who makes the chips and where.

In this episode, Dr. Miller explores how the chip industry evolved from independent manufacturing giants to specialized global supply chains and why that’s both a strength and a vulnerability. He breaks down the growing competition between the U.S. and China, the geopolitical risk of relying on Taiwan, and why the future of AI depends not just on better software but on smarter, faster hardware.

💡 Topics Covered:

Why semiconductors are the backbone of modern technology

The shift from integrated chip companies to design vs. manufacturing specialization

How legacy companies like Intel lost ground and what it means for the U.S.

The U.S./China tech rivalry and supply chain vulnerabilities

AI’s explosive growth and the chip race driving it

The surprising role of immigration in America’s tech dominance

Why even automakers and retailers are becoming chip-aware

On August 27, 1783, a large crowd gathered in Paris to watch the first ascent of a hydrogen balloon. Despite the initial feverish enthusiasm, by the mid-nineteenth century the balloon remained relatively unchanged and was no longer seen as the harbinger of a new era. Yet that all changed in the last third of the century, when following the traumatic Franco-Prussian War defeat, the balloon reemerged to become the modern artifact that captured the attention of many. Through this process, the balloon became an important symbol of the fledgling Third Republic, and France established itself as the world leader in flight. In Ascending Republic: The Ballooning Revival in Nineteenth-Century France (MIT Press, 2025), Dr. Patrick Luiz Sullivan De Oliveira tells for the first time the story of this surprising revival.Through extensive research in the press and archives in France, the United States, and Brazil, De Oliveira argues that French civil society cultivated popular enthusiasm for flight (what historians call “airmindedness”) decades before the advent of the airplane. Champions of French ballooning made the case that if the British Royal Navy controlled the seas and the Imperial German Army dominated the continent, then France needed to take ownership of the skies. The French appropriated this newly imagined geopolitical space through a variety of practices, from republican savants who studied the atmosphere at high altitudes to aristocrats who organized transcontinental long-distance competitions. All of this made Paris into the global capital of a thriving aeronautical culture that incorporated seemingly contradictory visions of sacrificial patriotism, aristocratic modernity, colonial anxiety, and technological cosmopolitanism.

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.

In this episode, host Sambhav Choudhury speaks with Shobhini Mukerji, Executive Director of J-PAL South Asia. From her transformative summer internship with education nonprofit Pratham to becoming a principal investigator on groundbreaking research, Shobhini shares her journey into development economics and experimental approaches.

Peoples & Things host, Lee Vinsel, talks with Matt Wisnioski, Professor of Science, Technology, and Society at Virginia Tech, about his new book, Every American an Innovator: How Innovation Became a Way of Life. The pair talk about how the new book connects to Matt’s earlier book, Engineers for Change; how what Matt calls “innovation expertise” first emerged; how government played a key role in promoting the idea of innovation; how the idea of innovation was democratized from focusing on elite white men to focusing on women, people of color, children, and, well, everyone; and much more. Vinsel and Wisnioski also talk about Matt’s current book project with Michael Meindl, Associate Professor of Communication at Radford University - a history of the television show and multimedia product, The Magic School Bus.

An Abundance of Caution: American Schools, the Virus, and a Story of Bad Decisions (MIT Press, 2025) is a devastating account of the decision-making process behind one of the worst American policy failures in a century—the extended closures of public schools during the pandemic. In fascinating and meticulously reported detail, David Zweig shows how some of the most trusted members of society—from Pulitzer Prize–winning journalists to eminent health officials—repeatedly made fundamental errors in their assessment and presentation of evidence. As a result, for the first time in modern American history, millions of healthy children did not set foot in a classroom for more than a year.Since the spring of 2020, many students in Europe had been learning in person. Even many peers at home—in private schools, and public schools in mostly “red” states and districts—were in class full time from fall 2020 onward. Whatever inequities that existed among American children before the pandemic, the selective school closures exacerbated them, disproportionately affecting the underprivileged. Deep mental, physical, and academic harms—among them, depression, anxiety, abuse, obesity, plummeting test scores, and rising drop-out rates—were endured for no discernible benefit. As Europe had shown very early, after they had sent kids back to class, there was never any evidence that long-term school closures, nor a host of interventions imposed on students when they were in classrooms, would reduce overall cases or deaths in any meaningful way.The story of American schools during the pandemic serves as a prism through which to approach fundamental questions about why and how individuals, bureaucracies, governments, and societies act as they do in times of crisis and uncertainty. Ultimately, this book is not about COVID; it’s about a country ill-equipped to act sensibly under duress.

David Zweig is the author of the novel Swimming Inside the Sun and the nonfiction book Invisibles. He has testified twice before Congress as an expert witness on American schools during the pandemic, and his investigative reporting on the pandemic has been cited in numerous congressional letters and a brief to the Supreme Court. Zweig’s journalism has appeared in The New York Times, The Wall Street Journal, The New Yorker, The Atlantic, New York, Wired, The Free Press, The Boston Globe, and, most often, his newsletter, Silent Lunch. He lives with his family in New York State.

Picturing Aura: A Visual Biography (MIT Press, 2025) by Dr. Jeremy Stolow is the first book of its kind: an extended historical, anthropological, and philosophical study of modern efforts to visualize the hidden radiant force encompassing the living body known as our aura. This rich, interdisciplinary study by Dr. Stolow chronicles the rise and global spread of modern instruments and techniques of picturing aura, from the late nineteenth century to the present day, exploring how its images are put to work in the diverse realms of psychical research, esotericism, art photography, popular culture, and the New Age alternative medical and spiritual marketplace.At their core, pictures of auras are boundary objects that operate simultaneously in multiple conceptual and practical realms, serving varying goals of making art, healing bodies, and exploring the cosmos. Drawing on extensive archival as well as field research, Stolow reconstructs a global history of this boundary-crossing enterprise through its evolving media technologies, markets, and cultural arenas. It is a story shaped through exchanges among professionals and amateurs, scientists and occultists, countercultural artists and entrepreneurs, metropolitans and hinterland figures. With more than 60 full-color illustrations, Picturing Aura brings to light a remarkable, entangled history of picture-making that challenges settled assumptions about religion, art, and science.
