Princeton UP Ideas Podcast

Claudia de Rham has been playing with gravity her entire life. As a diver, experimenting with her body's buoyancy in the Indian Ocean. As a pilot, soaring over Canadian waterfalls on dark mornings before beginning her daily scientific research. As an astronaut candidate, dreaming of the experience of flying free from Earth's pull. And as a physicist, discovering new sides to gravity's irresistible personality by exploring the limits of Einstein's general theory of relativity. In The Beauty of Falling: A Life in Pursuit of Gravity (Princeton UP, 2024), de Rham shares captivating stories about her quest to gain intimacy with gravity, to understand both its feeling and fundamental nature. Her life's pursuit led her from a twist of fate that snatched away her dream of becoming an astronaut to an exhilarating breakthrough at the very frontiers of gravitational physics.While many of us presume to know gravity quite well, the brightest scientists in history have yet to fully answer the simple question: what exactly is gravity? De Rham reveals how great minds--from Newton and Einstein to Stephen Hawking, Andrea Ghez, and Roger Penrose--led her to the edge of knowledge about this fundamental force. She found hints of a hidden side to gravity at the particle level where Einstein's theory breaks down, leading her to develop a new theory of "massive gravity." De Rham shares how her life's path turned from a precipitous fall to an exquisite flight toward the discovery of something entirely new about our surprising, gravity-driven universe.

Since the mid-2000s, the Chinese state has increasingly shifted away from labor-intensive, export-oriented manufacturing to a process of socioeconomic development centered on science and technology. In The Gilded Cage: Technology, Development, and State Capitalism in China (Princeton University Press, 2023) Ya-Wen Lei traces the contours of this techno-developmental regime and its resulting form of techno-state capitalism, telling the stories of those whose lives have been transformed—for better and worse—by China’s rapid rise to economic and technological dominance. Drawing on groundbreaking fieldwork and a wealth of in-depth interviews with managers, business owners, workers, software engineers, and local government officials, Lei describes the vastly unequal values assigned to economic sectors deemed “high-end” versus “low-end,” and the massive expansion of technical and legal instruments used to measure and control workers and capital. She shows how China’s rise has been uniquely shaped by its time-compressed development, the complex relationship between the nation’s authoritarian state and its increasingly powerful but unruly tech companies, and an ideology that fuses nationalism with high modernism, technological fetishism, and meritocracy. Some have compared China’s extraordinary transformation to America’s Gilded Age. This provocative book reveals how it is more like a gilded cage, one in which the Chinese state and tech capital are producing rising inequality and new forms of social exclusion.Ya-Wen Lei is professor of sociology at Harvard University, where she is affiliated with the Fairbank Center for Chinese Studies and the Weatherhead Center for International Affairs.Caleb Zakarin is Editor at the New Books Network.

A new economic history which uncovers the forgotten left-wing, anti-imperial, pacifist origins of economic cosmopolitanism and free trade from the mid-nineteenth to the mid-twentieth century. The post-1945 international free-trade regime was established to foster a more integrated, prosperous, and peaceful world. As US Secretary of State Cordell Hull (1933-1944), "Father of the United Nations" and one of the regime's principal architects, explained in his memoirs, "unhampered trade dovetailed with peace; high tariffs, trade barriers, and unfair economic competition, with war." Remarkably, this same economic order is now under assault from the country most involved in its creation: the United States. A global economic nationalist resurgence - heralded by Donald Trump's "America First" protectionism and resultant trade wars with the USA's closest allies and trading partners - now looks to transform over seventy years of regional and global market integration into an illiberal economic order resembling that of the late nineteenth and early twentieth centuries. Economic cosmopolitan critics of today's retreat from free trade have offered dire warnings that doing so would be catastrophic for global consumers and an existential threat to regional and world peace. But under what circumstances did this ideological marriage of free trade, prosperity, and peace arise? Who were its main adherents? How did this same free-trade ideology succeed in becoming the new economic orthodoxy following the Second World War? And how might the successes and failures of this earlier struggle to reform the economic order inform today's globalization crisis? In Pax Economica: Left-Wing Visions of a Free Trade World (Princeton UP, 2024), economic historian Marc-William Palen finds answers amid a century of transnational peace and anti-imperial activism that stretched from Britain's unilateral adoption of free trade in 1846 to the founding of the US-led liberal trading system that arose immediately after the Second World War. Over five thematic chapters, considering the period from different perspectives, and utilising archival research conducted in Europe, North America, and Australia, Palen shows that this politico-ideological struggle to create a more prosperous and peaceful world through free trade pitted economic cosmopolitans against economic nationalists. Cosmopolitans sought to counter the industrialising world's embrace of economic nationalism because they believed - much like today's critics of Trump's tariffs and Brexit - that economic nationalism laid the groundwork for trade wars, high prices for consumers, and geopolitical conflict; while free trade created market interdependence, prosperity, social justice, and a more peaceful world. Pax Economica argues that this cosmopolitan fight for free trade laid foundations for a century of anti-imperial and peace activism across the globe - and paved the way for today's global trade regime now under siege.

In 1995, a scandal erupted when the New York Times revealed that the Smithsonian possessed a century's worth of nude "posture" photos of college students. In this riveting history, Beth Linker tells why these photos were only a small part of the incredible story of twentieth-century America's largely forgotten posture panic--a decades-long episode in which it was widely accepted as scientific fact that Americans were suffering from an epidemic of bad posture, with potentially catastrophic health consequences. Tracing the rise and fall of this socially manufactured epidemic, Slouch: Posture Panic in Modern America (Princeton UP, 2024) also tells how this period continues to feed today's widespread anxieties about posture.In the early twentieth century, the eugenics movement and fears of disability gave slouching a new scientific relevance. Bad posture came to be seen as an individual health threat, an affront to conventional race hierarchies, and a sign of American decline. What followed were massive efforts to measure, track, and prevent slouching and, later, back pain--campaigns that reached schools, workplaces, and beyond, from the creation of the American Posture League to posture pageants. The popularity of posture-enhancing products, such as girdles and lumbar supports, exploded, as did new fitness programs focused on postural muscles, such as Pilates and modern yoga. By 1970, student protests largely brought an end to school posture exams and photos, but many efforts to fight bad posture continued, despite a lack of scientific evidence.A compelling history that mixes seriousness and humor, Slouch is a unique and provocative account of the unexpected origins of our largely unquestioned ideas about bad posture.

Parents everywhere want their children to be happy and do well. Yet how parents seek to achieve this ambition varies enormously. For instance, American and Chinese parents are increasingly authoritative and authoritarian, whereas Scandinavian parents tend to be more permissive. Why? Love, Money, and Parenting investigates how economic forces and growing inequality shape how parents raise their children. From medieval times to the present, and from the United States, the United Kingdom, Germany, Italy, Spain, and Sweden to China and Japan, Matthias Doepke and Fabrizio Zilibotti look at how economic incentives and constraints—such as money, knowledge, and time—influence parenting practices and what is considered good parenting in different countries.Through personal anecdotes and original research, Doepke and Zilibotti show that in countries with increasing economic inequality, such as the United States, parents push harder to ensure their children have a path to security and success. Economics has transformed the hands-off parenting of the 1960s and ’70s into a frantic, overscheduled activity. Growing inequality has also resulted in an increasing “parenting gap” between richer and poorer families, raising the disturbing prospect of diminished social mobility and fewer opportunities for children from disadvantaged backgrounds. In nations with less economic inequality, such as Sweden, the stakes are less high, and social mobility is not under threat. Doepke and Zilibotti discuss how investments in early childhood development and the design of education systems factor into the parenting equation, and how economics can help shape policies that will contribute to the ideal of equal opportunity for all. Love, Money, and Parenting: How Economics Explains the Way We Raise Our Kids (Princeton UP, 2019) presents an engrossing look at the economics of the family in the modern world.Matthias Doepke is professor of economics at Northwestern University.

In the middle of the second century AD, Rome was at its prosperous and powerful apex. The emperor Marcus Aurelius reigned over a vast territory that stretched from Britain to Egypt. The Roman-made peace, or Pax Romana, seemed to be permanent. Then, apparently out of nowhere, a sudden sickness struck the legions and laid waste to cities, including Rome itself. This fast-spreading disease, now known as the Antonine plague, may have been history’s first pandemic. Soon after its arrival, the Empire began its downward trajectory toward decline and fall. In Pox Romana: The Plague That Shook the Roman World (Princeton University Press, 2024), historian Dr. Colin Elliott offers a comprehensive, wide-ranging account of this pivotal moment in Roman history.Did a single disease—its origins and diagnosis still a mystery—bring Rome to its knees? Carefully examining all the available evidence, Dr. Elliott shows that Rome’s problems were more insidious. Years before the pandemic, the thin veneer of Roman peace and prosperity had begun to crack: the economy was sluggish, the military found itself bogged down in the Balkans and the Middle East, food insecurity led to riots and mass migration, and persecution of Christians intensified. The pandemic exposed the crumbling foundations of a doomed Empire. Arguing that the disease was both cause and effect of Rome’s fall, Dr. Elliott describes the plague’s “preexisting conditions” (Rome’s multiple economic, social, and environmental susceptibilities); recounts the history of the outbreak itself through the experiences of physician, victim, and political operator; and explores postpandemic crises. The pandemic’s most transformative power, Dr. Elliott suggests, may have been its lingering presence as a threat both real and perceived.This interview was conducted by Dr. Miranda Melcher whose forthcoming 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.

Myisha Cherry, associate professor of philosophy, discusses the limitations of traditional ideas of forgiveness and offers a new holistic approach. Topics include personal experiences shaping forgiveness, historical philosophical perspectives, nuances of forgiveness, and intersections with societal issues like racial dynamics and reparations.

On July 27th, 1827, the dey of Algiers struck the French consul over his country’s refusal to pay back its debts–specifically, to two Jewish merchant families: the Bacris, and the Busnachs. It was an error of judgment: France blockaded Algiers, and later invaded, turning Algeria into a French colony.The unpaid debt has festered as a diplomatic issue for almost 30 years. Foreign consuls in the corsairing capital of Algiers sent missives back to their superiors complaining about the Bacris and Busnachs and the doggedness they had in pursuing their debts.Julie Kalman writes about these two families–and their inter-familial business dealing and squabbles–in The Kings of Algiers: How Two Jewish Families Shaped the Mediterranean World during the Napoleonic Wars and Beyond (Princeton University Press, 2023).In this interview, Julie and I talk about the Bacris and the Busnachs, the strange relationships between Algiers, Britain, France and the U.S., and what “sanctions” and “debt diplomacy” looked like in the early nineteeth century.Julie Kalman is Associate Professor of history at Monash University. She has published widely on the history of French Jewry in the nineteenth century, and in the post-war period. She is also the author of Orientalizing the Jew: Religion, Culture and Imperialism in Nineteenth-Century France (Indiana University Press: 2017), and Rethinking Antisemitism in Nineteenth-Century France (Cambridge University Press: 2010).You can find more reviews, excerpts, interviews, and essays at The Asian Review of Books, including its review of The Kings of Algiers.

In Impermanent Blackness: The Making and Unmaking of Interracial Literary Culture in Modern America (Princeton UP, 2023), Korey Garibaldi explores interracial collaborations in American commercial publishing—authors, agents, and publishers who forged partnerships across racial lines—from the 1910s to the 1960s. Garibaldi shows how aspiring and established Black authors and editors worked closely with white interlocutors to achieve publishing success, often challenging stereotypes and advancing racial pluralism in the process.Impermanent Blackness explores the complex nature of this almost-forgotten period of interracial publishing by examining key developments, including the mainstream success of African American authors in the 1930s and 1940s, the emergence of multiracial children’s literature, postwar tensions between supporters of racial cosmopolitanism and of “Negro literature,” and the impact of the Civil Rights and Black Power movements on the legacy of interracial literary culture.By the end of the 1960s, some literary figures once celebrated for pushing the boundaries of what Black writing could be, including the anthologist W. S. Braithwaite, the bestselling novelist Frank Yerby, the memoirist Juanita Harrison, and others, were forgotten or criticized as too white. And yet, Garibaldi argues, these figures—at once dreamers and pragmatists—have much to teach us about building an inclusive society. Revisiting their work from a contemporary perspective, Garibaldi breaks new ground in the cultural history of race in the United States.Korey Garibaldi is Assistant Professor of American Studies at the University of Notre Dame.Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand.

Artificial intelligence may be the most transformative technology of our time. As AI's power grows, so does the need to figure out what--and who--this technology is really for. AI Needs You argues that it is critical for society to take the lead in answering this urgent question and ensuring that AI fulfills its promise.Verity Harding draws inspiring lessons from the histories of three twentieth-century tech revolutions--the space race, in vitro fertilization, and the internet--to empower each of us to join the conversation about AI and its possible futures. Sharing her perspective as a leading insider in technology and politics, she rejects the dominant narrative, which often likens AI's advent to that of the atomic bomb. History points the way to an achievable future in which democratically determined values guide AI to be peaceful in its intent; to embrace limitations; to serve purpose, not profit; and to be firmly rooted in societal trust.AI Needs You: How We Can Change AI's Future and Save Our Own (Princeton UP, 2024) gives us hope that we, the people, can imbue AI with a deep intentionality that reflects our best values, ideals, and interests, and that serves the public good. AI will permeate our lives in unforeseeable ways, but it is clear that the shape of AI's future--and of our own--cannot be left only to those building it. It is up to us to guide this technology away from our worst fears and toward a future that we can trust and believe in.
