Given the line element
we seek to find the metric tensors for raising and lowering indices for vectors and one-forms. We begin by noting that the metric tensor is symmetrical,
Between working on the book deal, writing the second draft of the book, finishing The Wonders of Physics, working a contract, and working on the Institute for Scientific Computing, I have not had a lot of time to work on the blog. We will be doing some storm chasing this weekend. I will post if we gets some good storm pictures.
I am busy, this week, with the Wonders of Physics (click here to go to the web site). This is a public demonstration show. Go to the web site and check it out!
