The internet just marked another major milestone. The first website, Tim Berners-Lee’s description of the World Wide Web project, went public 25 years ago on August 6th, 1991. The launch was unceremonious — Berners-Lee announced the project on a Usenet group, and it wasn’t until after August 23rd that new users visited the site. However, the launch effectively marked the start of the web as a widely available tool.
It’s long been accepted by physics that nature has supplied us with four fundamental forces. Gravity holds the planets and galaxies together, and the electromagnetic force holds us and our molecules together. At the smallest level are the two other forces: the strong nuclear force is the glue for atomic nuclei, and the weak nuclear force helps some atoms go through radioactive decay. These forces seemed to explain the physics we can observe, more or less.
