David Deutsch of Oxford University is my favorite physicist. He’s sharp as a tack, and sensible to boot. It’s always a pleasure to watch his videos on Robert Kuhn’s “Closer to Truth” youtube channel. Here’s one that I particularly like where he addresses the question “what are the limits of science?”
In the previous post “Economics and Physics” I briefly explored why the basic explanations of physics are hard to understand and why the basic explanations of economics are easy to understand. Physics is called a “hard science”. I believe it is hard in the sense that advances in physics are made by supremely intelligent people and even comprehending them requires a good deal of training and intelligence.
Physics is also hard in that it is not some soft and squishy, namby-pamby whatever goes kind of nonsense, unlike in some other intellectual enterprises where people just make up stuff as they go along.
