306. Video of the day: Stanford’s mobile phone orchestra
That’s apparently what they do in Stanford when they don’t study general relativity 
305. First two weeks of March on NEQNET
Here is a comprehensive list of physics questions and problems we have discussed here on NEQNET during previous two weeks:
1. String theory, field theory, quantum gravity
1.1. Chiral symmetry breaking in soft wall AdS/QCD model, where Tom Kelley (U. of Minnesota) shows how explicit and spontaneous chiral symmetry breaking takes place in a particular AdS/CFT-inspired model.

304. Science in Watchmen. How Ozymandias prevented Dr. Manhattan from seeing the future
If you have already seen “Wathchmen” (and/or have read the Moore’s graphic novel), recall that one of the main pillars of the storyline is the fact that Adrian Veidt (Ozymandias) used generators of tachyons located in his playboy hideout in Antarctica to prevent Dr. Manhattan from seeing the future and being able to affect Veidt’s plot of saving humanity from self-destruction.
303. Video of the day: Susskind’s lecture on general relativity 6
Just released… Previous lectures from the course can be found here. In this lecture (almost 2 hours!), Susskind discusses geodesics, parallel transport and curvature tensor.
300. Event horizon of Sgr A*
Dear friends,
I am really sorry for leaving you without a physics post (the video clearly cannot be counted ) – the reason was my faulty internet connection. The post that you will see below was almost ready but I wanted to make a short last check before it gets posted, and that’s when my faithful internet provider decided to cut me out. Anyway, all this just means that today you are going to have two nice posts instead of one.
