Joey Bernard gives a brief overview for Emacs for Science. He describes Emacs as a “slightly stranger tool in the arsenal of scientific computation”.
Emacs is a text editor that has almost all the functionality of an operating system. A collection of enhancements and configuration settings are available bundled under the name of scimax. Being an Emacs user myself, I was surprised I’d never heard of it before now. This project has been in development for some time, but it recently has started to find wider attention.
