Science History Podcast

The advent of agriculture over 10,000 years ago forever altered the trajectory of humanity. Communities grew larger until cities and nations dotted the landscape, labor became specialized, new diseases emerged, civilizations flourished and vanished, warfare increased in scale and lethality, and people colonized every corner of the globe. Agriculture facilitated the exponential growth of the human...

The brain is the most mysterious and complex organ of the body, and when things go awry, we may be confronted with personal tragedy and we may gain insights on what it means to be human. With us to discuss neurological disorders and the history of their discovery is Sara Manning Peskin. Sara completed an AB in biochemistry at Harvard University in 2009, an MS in cellular and molecular biology at t...

Nothing is so intertwined with human success and folly as economics. The economy, for better or for worse, drives much of our fate from our household budget to our national policies to the outbreak of war. But economic activity also has profound effects on the environment and a close inspection of economics opens the question of whether humans can live sustainably on the only planet we have. The f...

The 60s hosted the space race between the United States and the Soviet Union, which occurred in the midst of the Vietnam War, the Cold War, and civil unrest. How did the culture wars of the 1960s relate to the space race, especially in the United States? How did the Civil Rights Movement, the New Left, environmentalism, the women's movement, and the Hippie counterculture influence NASA, and vice v...

Today's episode marks the four-year anniversary of the Science History Podcast, where we have explored all manner of science and relevant policy spanning from gravitational waves to bioterrorism. So it is fitting that today's guest, Dick Garwin, has worked on just about every major scientific and technology problem with a defense application since just after the Second World War, ranging from the...

Today we explore the history of nuclear disarmament with Zia Mian. Zia is a physicist and co-director of Princeton's Program on Science and Global Security, part of the School of Public and International Affairs, where he has worked since 1997. His research interests include issues of nuclear arms control, nonproliferation and disarmament, and international peace and security. Zia is co-editor of...

How do we distinguish real science from hogwash? How does real science evolve over time into pseudoscience? Why will science always be plagued with sister movements on the fringe that make us cringe? With us to explore these topics and their relationship to the demarcation problem is Michael Gordin. Michael is the Rosengarten Professor of Modern and Contemporary History and the director of the Soc...

Uncertainty is inherent to science and exploited by those who wish to stymie regulations that would promote environmental quality and public health. Chemical companies, oil companies, tobacco companies, and many others, kept their products on the marketplace and promoted consumerism by stressing the unsettled nature of research. With us to explore this history, and how it relates to the environmen...

The study of wildlife has a history full of adventures in remote corners of the Earth, discoveries of remarkable behaviors, and achievements in conservation. George Schaller is a pioneer of the field, with seven decades of work spanning from the Arctic to the Tropics. George was born in Germany in 1933 and immigrated to the United States as a teenager. He received a BS degree from the University o...

The history of science is punctuated by both the greatest achievements and the greatest tragedies of human endeavors. The development of organic chemistry illustrates this dichotomy, as some scientists improved the human condition while others facilitated the horrors of genocide. The guise of chemistry also has served as a useful front for fraudsters. With us to illuminate chemical accidents, bril...

The history of mathematics extends back millennia. The needs of trade, taxation, and time-keeping drove the development of principles of arithmetic, algebra, and geometry, which had already acquired some sophistication by 5,000 years ago. Perhaps most fundamental to the development of mathematics has been discoveries on the nature of numbers themselves, or what mathematicians refer to as Number Th...

The most important book in the history of mathematics is Euclid's Elements. The book – really 13 short books bound together into a single treatise – dates to approximately 300 BC, and is credited to the Greek mathematician Euclid of Alexandria. It is apparently a compendium and expansion of the work of previous Greek mathematicians, such as Pythagoras, Hippocrates of Chios, and Eudoxus of Cnidus....

Galileo occupies an inflection point in the history of science and society. Born in 1564, Galileo changed the trajectory of science though his work in astronomy, physics and related fields. He invented various clever devices, and he used the telescope to push the boundaries of knowledge about our solar system and Earth's place in it. Galileo's discoveries, and the manner in which he presented them...

The creation of a new discipline based upon a single scientific expedition is a rare occurrence, but this is what resulted from the 1872-1876 expedition of H.M.S. Challenger. With us to explain the history and significance of the Challenger Expedition is Doug Macdougall. Doug is a geochemist who received a BS in geology from the University of Toronto, an MS in geology from McMaster University, and...

In the early 1990s, scientists discovered that sperm counts in industrialized countries had declined precipitously over the previous half century. It turns out that the incidence of other reproductive health problems beyond male infertility also increased in the latter part of the 20th century and into the 21st century. With us to discuss human reproductive health, and how it has changed in part d...

The boundaries of science are clear, and can be demarcated by the concept of falsifiability. Or so we learn in our science classes. But with some areas of science, falsifiability is not the critical feature, and may be impossible on theoretical or empirical grounds. Worrying about falsifiability might even get in the way of interesting ideas. With us to discuss the history of problems in science a...

Human health and environmental health are inextricably linked. We are negatively impacted by the same pollutants that harm other organisms, and we all live in a sea of synthetic chemicals that are part of our food supply, personal care products, the built environment, and just about every aspect of our lives. With us to gain a better understanding of the history of environmental health, especially...

How is it that corporations routinely and successfully obfuscate science and seed public doubt on issues of paramount importance, ranging from climate change to health effects of tobacco and pesticides? Who are the scientists for hire whose job is to muddy the waters on important policy issues? Why doesn't our government protect us from nefarious corporations that threaten our health and the envir...

Whistleblowers are admired or vilified. They are saviors of democracy or traitors to their country. They confront those in power and drive the news, and some, such as Edward Snowden and Chelsea Manning, are household names. But one man is their inspiration, the person who made whistleblowing a phenomenon of modern times, and his name is Daniel Ellsberg. Ellsberg was born in 1931 in Chicago and gre...

Pete Myers interviews me about my new book, The Chemical Age , published this month by the University of Chicago Press.

Why is it that decades after scientists discover problems of paramount importance, such as global climate change or lead pollution, those problems still persist? Why do corporations get away with producing products that harm human health or the environment? How do corporations shape our society, our politics, and even our psychology? With us to untangle these questions is my guest, Barbara Freese....

Discoveries in basic science often translate into material goods, and frequently in surprising ways. Material goods, in turn, facilitate scientific progress. Therefore, science and technology advance in tandem. Today we delve into the history of materials science with the help of Ainissa Ramirez. Ainissa is a scientist and science communicator, and the author of The Alchemy of Us: How Humans and M...

Today we explore what mathematicians would refer to as the non-trivial intersection between science and poetry. Guiding us through these overlapping sets is a person uniquely suited to the task, the science writer Dava Sobel. Dava is the author of prominent and best-selling science history books, including Longitude, Galileo's Daughter, The Planets, A More Perfect Heaven, and The Glass Universe. S...

Frogs have hopped around this planet for 200 million years. In comparison, anatomically modern humans have only been around for 200 thousand years. But the last half century has seen a tragic loss in amphibian biodiversity around the world. It seems especially striking that a group of animals that predate the dinosaurs have been devastated by modern human activities. With us today to discuss the h...

Chemistry has given the world the incredible diversity of fuels, pharmaceuticals, and household products that we rely on every day, along with tremendous advances in fighting infectious diseases and ensuring an abundant food supply. But the products of chemistry also include tens of thousands of toxic compounds that compromise human health, degrade the environment, and drive species to extinction....
