About Aron Wall
I am a Lecturer in Theoretical Physics at the University of Cambridge. Before that, I read Great Books at St. John's College (Santa Fe), got my physics Ph.D. from U Maryland, and did my postdocs at UC Santa Barbara, the Institute for Advanced Study in Princeton, and Stanford. The views expressed on this blog are my own, and should not be attributed to any of these fine institutions.
Today I'd like to talk about Bayes' Theorem, especially since it's come up in the comments section several times. It's named after St. Thomas Bayes (rhymes with "phase"). It can be used as a general framework for evaluating the probability … Continue reading →
I've told you so far that the gravitational field is encoded in a matrix known as the metric. Here it is, displayed as a nice table: There's 10 components because the matrix is symmetric when reflected diagonally. The 4 diagonal … Continue reading →
In my Pillars of Science series, I enumerated six aspects of Science that help explain why it works so well. It should be clear from my analysis that the characteristics of Science are quite flexible. All of the criteria are … Continue reading →
I've now completed my Pillars of Science series. My goal was to analyze why Science is such an amazingly effective method for discovering new truths about the world. Here are the 6 "Pillars" I identified. Of course, Science is a … Continue reading →
In my last post about spacetime, I explained how the geometry of spacetime is determined at each spacetime point by a set of 10 numbers. These 10 numbers are packaged together into a matrix called the metric, which is written … Continue reading →
