I am a mathematics graduate student looking to transition into theoretical physics. I am teaching myself by reading books and lecture notes, but I would like to have a more up-to-date perspective.
My broad question is then the following: which web resources would you recommend to familiarize myself with theoretical physics research, and more generally with the concepts and ideas of physics that would be new for a mathematician? I am looking for somewhat shorter reading material that I could read on a daily basis, as I have already many good books to read.
The question above might be too broad, so let me be more specific. I am looking for (one or more) blog(s), maintained by a researcher in theoretical physics, that describes her/his research and the techniques she/he uses (or finds interesting). The blog should be updated somewhat frequently.
To give a few examples from mathematics, Terence Tao's blog is an excellent resource both for learning a great deal about the boundaries of many research fields, but also for learning many useful techniques. Math ∩ Programming and Eventually Almost Everywhere are also excellent resources for news/learning for their respective fields.
I have done my best to check if this reference request had been answered elsewhere. Apologies if it had and I missed it.
