    I love your videos. You break down complicated subjects into something that is easy to understand. Thanks!

    As observações graficas das "diferentes distancias" percorridas pela luz, em diferentes referenciais e deduzidas nas transformações de Lorentz, não fazem sentido por si só, uma vez q os trajetos de luz observados, são componentes de feixes diferentes, "como" se a luz, análoga ao triangulo de potências, tivesse componentes ativa e reativa.

    Where does gamma come from.

      gamma is used because physicists were too lazy to keep writing 1 / sqrt ( 1 - (v^2/c^2)) over and over again, so they just called it "gamma" 😄

    Lorentz may be wrong. He is measuring the impedance loss of the system. It is similar to the apparent reduction in size of a person who is standing a long distance away. Artists use perspective in their drawings and paintings. The number you are calculating is the same as finding Pi through the Archimedes method.

      You are incorrect. This is a simple issue of the geometry of space and the fact that the speed of light is constant regardless of inertial reference frame.
      I suggest you watch this: th-cam.com/video/qXxtqK7G4Uw/w-d-xo.html

    ß=v/c but what is v ? c=3x10^8 m/c but v=? please help me because ı can't solve many question because of this problem..

    • @MichelvanBiezen
      @MichelvanBiezen  7 ปีที่แล้ว +2

      v is the actual velocity of the particle

      for 6 MeV elektron? ı had homework about stopping power..ı asked for this..particle's velocity had not given in it

    • @MichelvanBiezen

      A 6 MeV electron will have a velocity very close to the speed of light.

    • @erdiasilioglu
      @erdiasilioglu 7 ปีที่แล้ว +1

      but what?not equal to velocity of light because gamma will have undefine..ıf ı know this ı will solve all problem..ı need to know the absolute value of v for 6 MeV electron..

    • @MichelvanBiezen

      There are videos in the playlist that show you how to do that. Since the rest mass energy of an electron is 0.511 MeV, a 6 MeV electron has about 12 times its rest mass energy.

    Why cannot we say KE = 1/2 mv^2??

      You can't use that equation because it only applies in classical mechanics. In relativity, mass, time, and velocity are relative so we must use the Lorentz transformation equations.

    We hope you will add an Arabic translation, thank you

      We may be able to do that in the future.
