# Least Action

Nontrivializing triviality..and vice versa.

## Calligraphic symbols in LaTeX

If you’re unhappy with the way the standard amsmath/amssymb packages display a caligraphic L, and you want a more curly/loopy L for your Lagrangian density, then here’s a way out.

1. Install the package texlive-calrsfs. I had to run “yum install texlive-calrsfs” as superuser to accomplish this on Fedora 20.


3. The more loopy version of L is now mapped to \La, whereas the conventional version is \Lb.

Hope this helps!
