Hi, I was recently facing a problem in Newtonian mechanics vs. special relativity: textbooks represent Newtonian objects as 1-offset vector/matrices/tensors, while in special relativity they are 0-offset ones, by the addition of a time-like dimension.
I was drafting on my IPython notebook some ways to make classical mechanics work along with special relativity, and this problem seems to be an issue, unless it simply gets ignored by breaking compatibility with textbooks and by shifting indices when passing from classical to relativistic mechanics. Do you think that an offset on index-counting for vectors/matrices/tensors could be a good idea? -- You received this message because you are subscribed to the Google Groups "sympy" group.
