- I don’t know if I ever mentioned this, but quite a while ago I replaced the “latexrender” TeX plugin being used here by a mathjax one. As I find time, I’m now going back and editing old posts to get rid of latexrender tags and make the equations more mathjax friendly. As far as comments are concerned, you can add TeX content by using standard math delimiters \$, or \$\$ for displayed math. If you want to comment about US dollars, put a backslash before your dollar signs to avoid the interpretation as TeX.
One reason I hadn’t advertised this much is that I know it’s hard to get TeX right the first time, so people’s comments with TeX would be likely to often not work properly. I’ve added a plugin that lets you edit your comment for 5 minutes after you write it. This should be useful for typos, as well as for fixing TeX problems (note that you need to refresh the page to get the math to display).
- For a philosopher’s take on evaluating string theory, see this talk by James Ladyman, on Cosmic Dreams. Material on string theory is near the end, and just makes the obvious point that having no experimental evidence for the theory is a huge problem, no matter what efforts are made to change the usual way scientific theories are evaluated.
- A hot topic these days in the math community is the conjecture that local Langlands can be understood as geometric Langlands for the Fargues-Fontaine curve. My attempts to learn about this so far haven’t had a lot of success, but I now have new-found hope. At Harvard there’s a seminar going on this semester on the topic, and it has a website which so far features explanations of some of the mathematics involved from Jacob Lurie and Dennis Gaitsgory. In London, the London Number Theory Seminar also has a study group devoted to this topic (website here, although seems to have disappeared for the moment).
- LQP2 (Local Quantum Physics Crossroads, v.2.0) is a website that gathers various information about relativistic quantum theory.
- In November Perimeter will host what should be an interesting workshop on the question of how to make sense of the Path Integral for Gravity.
- A memorial for Maryam Mirzakhani will take place at Stanford on October 21, with a live feed available here.
- As always, Quanta magazine keeps publishing a wide range of very high quality articles about math and physics, covering different topics than everyone else. Most recently, on the math side, see an article by Erica Klarreich on Pariah Moonshine and on the physics side, Robert Henderson on possible searches for long-lived particles possibly from a “hidden sector”..
Update: Commenter sdf points out this historical article by Pierre Colmez about the Fargues-Fontaine curve, preprint of a preface to an Asterisque volume.
