  1. What Has the Pandemic Taught Us About Vaccines?

    Should Covid-19 vaccines be judged by how well they prevent disease or how well they prevent death? Anna Durbin, a public health expert and vaccine researcher, talks with Steven Strogatz about the science behind vaccines. The post What Has

  2. Is There Math Beyond the Equal Sign?

    Can mathematics handle things that are essentially the same without being exactly equal? Category theorist Eugenia Cheng and host Steven Strogatz discuss the power and pleasures of abstraction. The post Is There Math Beyond the Equal Sign?

  3. Can We Program Our Cells?

    By genetically instructing cells to perform tasks that they wouldn't in nature, synthetic biologists can learn deep secrets about how life works. Steven Strogatz discusses the potential of this young field with researcher Michael Elowitz.

  4. How Will the Universe End?

    "The Joy of Why" is a podcast about curiosity and the pursuit of knowledge from Quanta Magazine. The acclaimed mathematician and author Steven Strogatz interviews leading researchers about the great scientific and mathematical questions of

  5. The Joy of Asking About Infinity, Jellyfish and the End of the Universe

    As The Joy of Why podcast returns for a second season, producer Polly Stryker and host Steven Strogatz invite listeners to join them and their brilliant new guests on another voyage of discovery.

  6. Why and How Do We Dream?

    Dreams are subjective and fleeting, but laboratories have developed ways of getting into the minds of people while they are dreaming. In this episode, Steven Strogatz speaks with sleep researcher Antonio Zadra about how new experimental met

  7. What Is Quantum Field Theory and Why Is It Incomplete?

    Quantum field theory may be the most successful scientific theory of all time, but there's reason to think it's missing something. Steven Strogatz speaks with theoretical physicist David Tong about this enigmatic theory.

  8. Why Do We Get Old, and Can Aging Be Reversed?

    Everybody gets older, but not everyone ages in the same way. In this episode, Steven Strogatz speaks with Judith Campisi and Dena Dubal, two biomedical researchers who study the causes and outcomes of aging, to understand how age works - an

  9. How Do Mathematicians Know Their Proofs Are Correct?

    Just as scientists test hypotheses, mathematicians prove or disprove conjectures. But what makes a proof stronger than a guess? What does evidence look like in the world of mathematics? Hear Melanie Matchett Wood, professor of mathematics a

  10. Can Computers Be Mathematicians?

    Artificial intelligence has bested humans at problem-solving tasks including games like chess and Go. Is mathematics research next? Steven Strogatz speaks with Kevin Buzzard, professor of pure mathematics at Imperial College London, to lear

  12. How Could Life Evolve From Cyanide?

    How did life arise on Earth? It's one of the greatest and most ancient mysteries in all of science - and the clues to solving it are all around us. Steven Strogatz speaks with Jack Szostak, a Nobel Prize-winning biologist, and Betül Kaçar,

  13. Will the James Webb Space Telescope Reveal Another Earth?

    With the December 2021 launch of the James Webb Space Telescope, one of the most expensive and ambitious scientific initiatives ever attempted commenced operations. Now that the telescope has been successfully deployed in its unique positio

  14. Where Do Space, Time and Gravity Come From?

    Einstein's description of gravity as a curvature in space-time doesn't easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll (of the "Mindscape" podcast) tells Steven Strogatz about the mind-bendin

  15. Why Is Inflammation a Dangerous Necessity?

    We've heard a lot about the immune system during the COVID-19 pandemic, but of course our immune system fights off much more than the coronavirus. And while the immune system protects us brilliantly from countless pathogens every day, somet

  16. Untangling Why Knots Are Important

    Everyone knows what a knot is. But they have special significance in math and science because their properties can help unlock hidden secrets like the biochemistry of DNA or the geometry of three-dimensional spaces. In this episode, Steven
