Hello there, thanks for visiting my webpage. I'm Justin C. Feng, a physics graduate student working under the supervision of Prof. Richard Matzner at the Center for Relativity.

Research Interests

My research is a mixture of theoretical and numerical work in General Relativity. In particular, I work on topics involving variational principles in General Relativity, the 3+1 formalism and the Post-Minkowskian approximation. I also do research in Hamiltonian theory, path integrals and quantum gravity.


In the past, I was a teaching assistant for Physics 102M, Physics 303L, and Physics 315. I'm currently Assistant Instructor for the Division of Physical Science. This summer, I will be teaching Physics 303, and an informal crash course in General Relativity for interested undergraduates.

I will also be teaching Physical Science 303 in the fall semester.


My Notes:

The Poor Man's Introduction to Tensors - These are my Mathematica notes on tensors--These are intended to serve as an informal introduction to tensor calculus without the distractions of non-Euclidean geometry. (Updated 06-04-2015)

General Physics Links:

How to Learn Math and Physics (Baez) - This is a good place to get an overview of the subjects that physicists study.

Theoretical Physics as a Challenge (T'Hooft) - This is another good place to get an overview of the subjects that physicists study.

A Physics Booklist - This list covers many of the major textbooks that one would encounter in his or her physics education.

The Net Advance of Physics - This is a great place to start if you want to find reviews on just about any topic in physics.

The arXiv - This is where physicists get their news. Here, you get to see research papers before they're published. The arXiv also provides free access to just about any physics or mathematics paper published within the past 20 years.

John Baez's Stuff - If you're bored, you can find some light physics reading material here.


General Relativity Links:

A Guide to Relativity Books - This is a list of books on General Relativity. It's a bit out of date now (it doesn't include Sean Carroll's book), but it includes a lot of obscure ones.

Living Reviews in Relativity - If you're looking for reviews on topics in General Relativity, you can find them here.

arXiv: General Relativity and Quantum Cosmology - This is the General Relativity section of the arXiv, for your convenience. Bookmark it.

hyperspace@aei - Here is where you get all the General Relativity news you can't find on the arXiv, like conference information, job openings, and awards.

UT Center for Relativity - This is the webpage for the UT Center for Relativity.
