    According to Arthur Miller book - Albert Einstein's special theory of relativity - Galilean transformations were not named until 1911. Abraham Pais gives different date of 1908. But the point is - Lorentz transformations came before Galilean transformations. Calling them Galilean transformations gives the false impression that they came from Galileo before Einstein's relativity. But fact is - it was Einstein's relativity first in 1905 followed by Galilean relativity a few years later. (Calling it Galilean relativity is thus a misnomer - it wasn't anything that Galileo dealt with.) I also pick up on what Miller says about Einstein being mistranslated into English. My Einstein mistranslated video at - ruclips.net/video/eCfzuAZi_rA/видео.html What "they" have done is make a gigantic mess of everything; mess up the history of relativity; mess up the translating of it into English; mess up the math etc etc.

      I consider the related sentence from Engelhardt, the most thorough and the truest sentence about the theory of relativity. It takes time for one to really understand this sentence (one need to study the history and the mathematics). Poincare (mathematician specialized in complex space transformations and groups) called "Lorentz transformation" auxiliary variables used by Lorentz (Lorentz called them auxiliary variables). Lorentz (in his book and in a letter to Voigt) admitted that he took this change of variables from Voigt (from Voigt's 1887 paper, "On the Doppler's principle"). This of course do not contradict the well-known work done by Mileva Maric on Einstein’s papers (writing the equations, performing experiments on photo-electric effect, etc.).

      @profhalimboutayeb 2 месяца назад

      @@oeq57 You are right the speed is not realistic, but the simulation gives an idea about the Doppler effect. The results for realistic speeds can be obtained by extrapolation. It would not be possible to simulate for realistic speeds directly, it would take forever. The relativistic effects are neglected.

    Great video! Also relativity is cheered up because the transformations make the Maxwell-Lorentz electrodynamic equations lorentz covariant BUT the full Maxwell-Hertz equations are GALILEAN INVARIANT. Also Weber's Theory published in Maxwell's Treatise is Galilean Invariant. The idea alone that physics have gone off rails more than 100 years ago, makes one brain explode.
