A while back Mitchell Porter decided it was less important to blog about climate change because nanotechnology will kill us all. Now he’s blogging about n=4 super-Yang-Mills theory, whatever that is. Chris from Mixing Memory is alive and well according to an unnamed internet person. I think the last name I mentioned Mitchell I also brought up Vichy’s new blog, but now that’s the old one and the new one is here, although testing now it appears to be private.
