Symmetry: How Einstein Changed the Way We See Everything
Nobel Prize-winning physicist Frank Wilczek details the broad influence Albert Einstein had on his career, as well as society as a whole.
Frank Wilczek: [Albert] Einstein was a great hero of mine and he’s played an important role in my life. In many ways I try to write, to model my scientific expositions and style on the early Einstein. For several years I owned and lived in Einstein’s house in Princeton. I was kind of his — in that sense his successor at the Institute for Advanced Study. He added profound themes to our understanding of nature at a technical level. He really advanced, although he didn’t articulate it explicitly by example, he advanced the idea that symmetry is what’s very basic to the operation of fundamental law.
In the special theory of relativity he showed that by postulating symmetry, that is that the laws don’t change although they might have if you move past a physical situation at a constant velocity, the same laws still apply to that different-looking situation. That kind of very conceptual idea of how physical law is constrained set a new style in physics that you assume that the world doesn’t change when it might have under various transformations. That’s been really — that really has been a dominant theme of 20th century physics and of my own work. He carried it further in the general theory of relatively where he postulated a new kind of symmetry called, so-called local symmetry which is vaster and leads to even more constraints on the possible description of the world and even more particular guidance about what the equations should look like. And that kind of strategy has been spectacularly successful in a generalized sense, although we need some extra tricks.
But in the generalized sense that’s the main trick that allowed us to figure out not only the correct theory of gravity or actually a very, very good theory of gravity, which is Einstein’s general theory of relativity, but also in the subnuclear domain where we had to guess fundamentally new laws for fundamentally new interactions, which were very unfamiliar. The so-called strong and weak interactions. It turned out that this kind of hypothesis of grand symmetry was the right way to go. So in addition to being a beautiful idea, it's turned out to be an extremely fruitful idea. It's led us to a description of interactions where new kinds of forces where otherwise we would have been completely at sea.
In this video interview, Nobel Prize-winning physicist Frank Wilczek details the broad influence Albert Einstein had on his career, as well as his influence on society as a whole. And since Wilczek is the author of a new book on natural design, we learn much about Einstein's impact on the study and theory of symmetry.
