Special Relativity Symmetry $$ t' = \gamma(t - \frac{v}{c^2}x) \\ x' = \gamma(x - vt) $$or: $$ ct' = \gamma(ct - \beta x) \\ x' = \gamma(x - \beta ct) $$Which is same for interval as a vector. What does it say? It means we describe the 4-vector component in another frame $\Sigma’$ by $\Sigma$. That’s means basis will changes reversely($t’ \hat{t’} + r’ \hat{r’}$). It’s symmetric that $x’^\mu = \Lambda^\mu_\nu x^\nu \lrarr x^\mu = \Lambda^{-1 \mu }_\nu x^\nu$. ...
Collaboration Rules You can set rules for collaboration and to prevent safety issues. Usually, you want to prevent someone from modifying the main branch arbitrarily and restrict all push behavior after a careful check on PRs. Settings Rules restrict creations restrict update restrict deletions block force pushes Here are some simple block rules you may want to set. Pull Request You should create a new branch to avoid conflicts with your modifications, then create a new pull request to submit changes. ...
