Hello readers!

Some of you have probably read the guide to N=4 super Yang-Mills theory linked at the top of my blog’s home page. A few of you even discovered this blog via the guide.

I’m thinking about doing another series of posts, like those, explaining a different theory. I’d like to get an idea of which theory you guys are most interested in seeing described. Whichever I choose, it will be largely along the same lines as the N=4 posts, so focused less on technical details and more on presenting something that a layman can understand.

Here are some of the options I’m considering:

• N=8 Supergravity: Very broadly speaking, this is gravity’s equivalent of N=4 super Yang-Mills. It’s connected to N=4 in a variety of interesting ways, and it’s something I’d like to work more with at some point.

• The (2,0) Theory: This was the motivation behind my first paper. It’s harder to explain than some of the other theories because it doesn’t have an easy analogy with the particles of the real world. It’s also even harder to work with, to the point that saying something rigorous about it is often worthy of a paper on its own.

• String Theory/M Theory: This is a big topic, and there are many sites out there already that cover aspects of it. What I might try to do is look for an angle of approach that others haven’t covered, and try to explain some slightly more technical aspects of the situation in a popularly approachable way.

I could also give a more detailed description of some method from amplitudeology, like generalized unitarity or symbology.

Finally, I could always just keep posting like I have been doing. But this seems like a good time to add to my site’s utility. So what do you think? What should I talk about?
