[Auszug] If g(?) is the Fourier transform of f(t), then g(??) is the Fourier transform of f(? t). If g(?)=g(??) then f(t)= f(? t). If g(?) is an even function of frequency then f(t) is an even function of time. If f(t) is an even function of time it is precursive. The experimental evidence for the isotropic ...
