Leroy is a former NASA astronaut and International Space Station commander. A veteran of four space missions, Leroy most recently served as Commander and NASA Science Officer of Expedition 10 aboard the...

Marie Curie was one of the most remarkable scientists in history. She was the first woman to win a Nobel Prize, the first person to win two, and the only person ever to earn Nobel awards in separate fields of science. Today we explore the life and legacy of Marie Curie with the science writer Dava Sobel. Dava is the author of prominent and best-selling science history books, including Longitude,...

On July 9, 1955, mathematician and philosopher Bertrand Russell announced the Russell-Einstein manifesto, which warned the world of the dangers posed by nuclear weapons. The 11 signatories included Albert Einstein, who signed it just before his death. Physicist Joseph Rotblat stated that the manifesto was "the last message from the man who was the symbol of the great heights the human intellect...

What did the ancient world discover about the cosmos? What were the contributions of Copernicus, Kepler, and Galileo? How did the science of astronomy advance under Newton? And how did everything change again with the discoveries of special relativity, general relativity, and quantum mechanics? With us to answer these questions is Sarah Alam Malik. Sarah is an expert on dark matter, and her work...

Chemical exposures in the womb can lead to what biologists call organizational effects - that is, impacts on the developing child that are irreversible. How were developmental problems associated with chemical exposures during pregnancy first discovered? And how did these discoveries influence policy? With me to discuss chemicals and child development is Tracey Woodruff. Tracey is a professor in...

The age of exploration altered the course of human history, but how did early explorers find their way? Calculating their latitude at sea was a relatively straightforward proposition, but calculating longitude presented a vexing problem. Given the big power competition for colonies, conquest, and riches, the search to discover an accurate means of assessing longitude became a scramble. A major...

Today we explore the life and legacy of the physicist Niels Bohr through the reflections of his grandson Tomas Bohr. Tomas is an Emeritus Professor at the Technical University of Denmark. He studies fluid dynamics, biophysics, chaos, turbulence and statistical mechanics, and he has a long and distinguished career publishing in these fields. He is a member of the Royal Danish Academy of Sciences...

Often in the history of science, myths overrun scientific findings and take hold with such force that they are difficult or nearly impossible to dislodge from public understanding. Perhaps no example of this phenomenon is more pronounced than that of the societal collapse of Easter Island, also known as Rapa Nui. With us to unravel the myth from the science is Mike Pitts. Mike is a writer and...
