Physics & Computation Blog Post Round-up

In the Fall, Boaz and I co-taught a grad seminar on physics and computation (see here for some of the original press coverage). We were lucky to attract an intrepid group of students from multiple fields, with representatives from computer science, physics, math and biology. As part of the course, we asked our students to give presentations and write expository blog posts on a number of topics at the intersection of computation and physics, including algorithms from statistical physics, quantum area laws, and the firewall paradox. The students worked hard to produce posts that make the physics concepts accessible to a computer science audience, and the result is a nice collection of posts that create a “bridge” from CS to physics.

Here, the aim is to give a (long overdue) table of contents for their posts. Followers of the blog may have noticed a landslide of physics & computation posts around December and January; if you weren’t able to keep up with them all at the time, then here they are, rounded up and organized by topic.

One thought on “Physics & Computation Blog Post Round-up

  1. An impressive collection! BTW I have talked to some serious physicists who think the Black Hole paradox may not be a paradox at all. They explained why, though I am expert enough to reproduce their explaination. Somehow I had not seen this discussed in the popular media coverage…

    But thanks for all the work!
