The Elements of Marie Curie with Dava Sobel

About This Episode

How did Marie Curie’s discoveries in radioactivity change our understanding of the natural world? Neil deGrasse Tyson and comedian Chuck Nice sit down with science writer Dava Sobel, author of a new book on Curie, to explore the enduring impact of her work on radioactivity.

Discover how Curie’s meticulous research led to the isolation of radium and polonium—elements that unlocked the mysteries of radioactivity and laid the foundation for modern physics and chemistry. Learn how her insights paved the way for radioactive dating, which determined the Earth’s age, and her revolutionary contributions to medical science, including the use of radium to treat cancer and the development of mobile X-ray units during World War I.

We dive into the science behind her two Nobel Prizes—one in physics and one in chemistry—and her perseverance in refining tiny quantities of radioactive material from tons of ore. We also discuss the risks she and her collaborators faced as the dangers of radiation exposure became clear, as well as the scientific advances inspired by her work, including the creation of artificial radioelements for medical applications.

From her early experiments to her lab notes—still radioactive today—Curie’s story is one of unrelenting curiosity and dedication. Join us for a deep dive into the science that defined her career and the discoveries that continue to shape our understanding of the universe.
