Watch the leaders of physics wrestle with the riddles of their subject.

  • An Interview with Richard Healey [Video]

    It stands to reason that electromagnetism is a theory of electric and magnetic fields. But since when is anything in physics so straightforward? Although Maxwell’s equations of electromagnetism in their usual formulation do contain electric and magnetic fields, those equations can be rewritten in terms of a mathematical function called the potential. So what is […]

  • An Interview with Daniele Oriti [Video]

    If spacetime is made of atoms, as many theoretical physicists these days speculate, could we ever know? You might doubt it. Conventional wisdom says those atoms would be too small, too energetic, or just plain too weird. But Daniele Oriti thinks we have a shot.   Oriti, an Italian theorist working at the Max Planck […]

  • Why is Quantum Physics So Freakin’ Hard to Write About? [Video]

    Every area of journalism presents its challenges, but quantum physics is in a molecular orbital of its own. It demands more time per word than anything else I’ve written about. Why is that? Earlier this month I offered some thoughts to fellow science journalists attending a philosophy-of-physics workshop at the University of Leeds.     […]

  • An Interview with Daniel Sudarsky [Video]

    Quantum physicists do love their beer. By day they build instruments, measure numbers, solve equations. By night they retire to the bar or pub and muse about the philosophical puzzles of quantum theory. By “philosophical” they mean “fun but impractical.” Maybe quantum theory betrays the existence of parallel universes, maybe it exposes causal influences coming […]

  • An Interview with Karen Crowther [Video]

    The nice thing about philosophers of physics is that they have no dog in the fight among string theory, loop quantum gravity, and other competing approaches to a fundamental theory of nature. They can stand back and offer some third-party perspective. One who specializes in this is Karen Crowther, a postdoc in the University of […]

  • Entanglement as the Glue of Spacetime [Video]

    Here’s a talk I gave at the Centre for Quantum Technologies in Singapore on March 24, 2016. Note that it was the first time I’d given this particular talk and it had a couple of first-iteration glitches.  

  • FAQ: How Are Entangled Particles Created? [Video]

    The number-one question that people ask me when I talk about nonlocality is: how are entangled particles created? I didn’t say much about this in the first edition of my book because the details don’t matter for my overall argument, but since everyone wants to know, I figure I should elaborate. (I’ve also added an […]

  • Spooky Action at a Distance at Google [Video]

    On February 10, 2016, I gave a summary of my book to the good folks at Google New York.  

  • An Interview with Howard Wiseman [Video]

    If anyone is the Kissinger of quantum physics, striving to forge peace in the century-old dispute over the meaning of the quantum, it is Howard Wiseman. A theoretical physicist at Griffith University in Brisbane, Australia, Wiseman thinks the debate hasn’t been resolved because it can’t be, given our present state of knowledge. Only when physicists […]

  • An Interview with Thanu Padmanabhan [Video]

    I’m fascinated by how the humblest observations can lead you to the profoundest conclusions, and here’s one I learned from Thanu Padmanabhan, an eminent theoretical physicist at the Inter-University Centre for Astronomy and Astrophysics in Pune, India. Suppose you cup your hands around a glass of cold water to warm it up. From this simple […]
