How to get remote jupyter to automatically open a local browser.

I just created a repo on github for computing complete elliptic integrals in javascript. The README.md is below, and a demo after that. You might ask yoursel...

If you’re in the intersection of git, emacs, and persnickety about whitespace.

Just one more committee

I hosted a Quora session. It went well!

An identity between vector commutation coefficients and coframe connection coefficients

These three objects form a superalgebra! Whoa!

When can you integrate-by-parts with Lie derivatives?

Special thanks to Ben Mares for coming up with this identity.

There is a nice 4-dimensional Weyl identity that I can never seem to remember off the top of my head; so I decided I need to write this note so I don’t have ...

The Weyl decomposition, further splitting into E/B, and computing in terms of 3+1 objects

In an effort to keep myself organized, I decided I should type up some notes I have laying around.

One of the first numerical simulations of black hole mergers in beyond-GR effective field theories

Angular momentum is tricky to define in GR! Here’s an approach so that observers can all agree with each others’ measurements.
