An Interview with Emily Adlam [Video]

Spooky influences might leap not just across space, but across time, too.

The mysteries of quantum mechanics are usually portrayed as mysteries of space: how strange that the fates of particles on opposite sides of the universe could be joined. But they are also mysteries of time. A particle you create today could be connected in some unaccountable way to one that does not exist yet. Einstein […]

An Interview with Richard Healey [Video]

Entanglement is not the only type of nonlocality in quantum theory.

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]

The atoms of space may be tiny, but could have huge effects.

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 Institute […]

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

Short answer: It’s largely a self-reinforcing expectation.

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. Although my […]

An Interview with Daniel Sudarsky [Video]

To test the interpretation of quantum mechanics, look to cosmology.

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]

When physicists get stuck, call in the philosophers.

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]

A slightly more technical version of my book talk

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]

Shine a laser on a nonlinear optical crystal to get streams of entangled photons.

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]

My book talk at Google

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]

The debate over quantum nonlocality awaits its resolution in a unified theory of physics.

If anyone is the Kissinger of quantum physics—in a good way, 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 […]
