In the opening pages of volume one of Polchinski's "String Theory", we are immediately introduced to an expression for the action of a relativistic point particle.

In the last entry, we looked into a study of the nonrelativistic string and derived the appropriate equation of motion. In the process, a number of comments were directed toward the reader to pay closed att...

For pedagogical purposes, I think prefacing an engagement with Polchinski's "String Theory" with a short study of nonrelativistic strings is reasonable. Although the first pages of the book immediately engage...

As a first entry it is worth mentioning that the following notes, which I will upload to this blog over time, are the product of my studies in string theory.

Seeing how I wrote a new post yesterday in the area of tensor analysis, I was reminded of the beautiful result below. It likely would have made it onto this blog at some point, so I thought I would quickly ...

The metric tensor is ubiquitous when arriving at a certain level in one's physics career. When it comes to cyndrilical coordinates, there is a useful way to remember its deeper meaning through a rather simp...

Some time ago I wrote a post on human evolution and civilisation. It was one of my first contributions to my general reading blog. But I feel it is worth thinking about this morning, as, generally, this is what...
