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 Thanu Padmanabhan [Video]

“Atoms” of space are too small to see, but betray themselves indirectly.

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 […]

An Interview with Juan Maldacena [Video]

The holographic principle, as explained by the man who has done more than anyone else to understand it.

The holographic principle is arguably the most tangible and tantalizing clue to a quantum theory of gravity, but for years physicists didn’t know what to make of it. That changed in 1997 when Juan Maldacena, now at the Institute for Advanced Study, came up with the first concrete example of what the principle means and […]

A Hologram Shows How Space Could Pop Into Existence

The holographic principle—with a real hologram

I remember buying my first hologram as a college student in the mid-1980s. It showed a bed of nails. I came across it at a gallery in what was then the world’s capital of spacey trinkets, Haight Street in San Francisco. When I picked it up, the hologram looked like a featureless sheet of film, […]

Does Some Deeper Level of Physics Underlie Quantum Mechanics? An Interview with Nobelist Gerard ’t Hooft

Is the notorious randomness of quantum mechanics just a front?

VIENNA—Over the past several days, I attended a fascinating conference that explored an old idea of Einstein’s, one that was largely dismissed for decades: that quantum mechanics is not the root level of reality, but merely a hazy glimpse of something even deeper. A leading advocate is Gerard ’t Hooft of Utrecht University, who shared […]

It From Bit or Bit From It? The Fifth Foundational Questions Institute Essay Contest

What a great way to start the week: the Foundational Questions Institute has just announced its fifth essay contest. The topic is the physics of information. It could hardly be more timely, and not just because of the cultural Zeitgeist. Going to a physics conference these days is like landing in The Village of the […]
