    It took us 255 years to go from Galilean transformations for falling bodies to Lorentz transformations that are in accordance with Einstein's special relativity.pic.twitter.com/hY8F60VogW

        where γ is the Lorentz factor that depends upon the velocity of the moving object and is given by: γ = 1/√(1-v²/c²) It oscillates between 1 (for objects at rest) and 0 (for speed of light) so the above formulae would be expanded into these forms-pic.twitter.com/j0EI6ubv1A

        Is there a math demonstration that takes us there clearly explained somewhere ? What I hated in Physics was that all those formulas were imposed upon us, never demonstrated and that the teacher wasn't usually able to resolve an equation beyond the 3rd line.

        Do you know Hudson-Nelson University physics book? Or Feyman lectures? They could help if you understand calculus.

        255 is the product of the first three Fermat primes and also the maximum value representable by 8-bit, that's why it took us so long.

        Yeah, and then it only took Einstein a decade to invent General Relativity, which takes gravity into account, and everyone who mattered, pop sci writers excluded, kinda forgot about "Special" Relativity. E=mc2 is where it's at since about a century, not this curious special case.

        Ironically, E=mc^2 is a special case of a more general formula that can be derived starting from lorentz transformations.
