Theory of Everything

1. A short introduction to the history of physics, and string theory as a “Theory of Everything”

2. M-theory and dualities


The first article explains what string theory is and why many physicists study it. The second article explains what the first superstring revolution and the second superstring revolution are in laymen’s terms. I also explain the significance of my calculation of string coupling constant. The last article derives a simple mathematical relation that is very important in string theory.
