I write drafts on paper. It would be nice if the electronic versions of documents looked similar to the drafts. It would be even better is the same paper-like form could be used for a web site with all its menus and an eBook with all the chapters. In this blog, I will go over the technology stack I use to present the same simple text on a web site and an eBook. This works for a static web site (things are added only once in a while). One needs to be comfortable with open source software, and tweaking other people's code a little.
Each January, I scamper out of the basement and talk to folks during MIT's Independent Activities Period. The Alumni Association is the sponsor (no one from the physics or math department is inviting me).
Relativistic quantum field theory does not apply to everyday life. It doesn't apply to one beam circling the Large Hadron Collider (LHC). When two beams traveling in opposite directions smash together, that is when the crazy magic of relativistic quantum field theory dominates. In order to calculate the odds of scattering events, the sum of all possible histories must be accounted for.
