    Graduate Is the rotation angle in Minkowski's diagram real or imaginary?

    Scott Walter (http://www.univ-nancy2.fr/DepPhilo/walter/), who published several papers on Minkowski and his diagram, wrote on page 9 of this article http://www.univ-nancy2.fr/DepPhilo/walter/papers/nes.pdf We can see now not only that it does make sense to describe a Lorentz transformation as...

    Thanks Kuon! If I understand correctly, you come with a third possibility, right? :smile:

    Graduate Is the rotation angle in Minkowski's diagram real or imaginary?

    In Figure_1(b) I have depicted a simplified version of Minkowski's diagram, where \beta = \frac{v}{c}= \tanh \psi= - i \tan i \psi= \frac{( e^{\psi} - e^{-\psi})}{( e^{\psi} + e^{-\psi})} , the rotation of (x',t')-axes being defined as imaginary (considering x and t real, and c=1)...
