I was recently in an art supply store and saw a print of a vintage periodic table that I thought had real aesthetic value. I bought it and like any enthusiast I hung it in my bathroom. For the past month I have been studying it as I brush my teeth and feel comfortable with 80% of the...
Hello guy with the scary picture! I highly recommend https://www.amazon.com/dp/0957389442/?tag=pfamazon01-20 . It starts with a basic review of the math you need and gently leads you through everything! It helped me a lot before I tried more academic books.
This may seem an odd question but it will clear something up for me. Are "The spacetime interval is invariant." and the "The spacetime metric is a tensor." exactly equivalent statements? Does one imply more or less information than the other?
Thanks!
Thanks Mentz114 very interesting reply. The man was a true giant!
If you don't mind ... did anything useful come out of his work on a unified field theory? I understand he believed all physics could be described with geometry as he achieved with gravity. Did any that work contribute to physics?
I forgot to mention I found the emphasis on the association between basis vectors and components to be powerful. It leads to moving beyond thinking of a vector as an arrow to thinking of it as one of many possible associations between basis vectors and components. This generalized association...
I enjoyed this video about tensors very much. I would recommend it to anyone seeking to understand the concept in general and general relativity specifically.
