The Frequencies Of Life Are A Relative Matter ソックス

Showcase your wry physics attitude with this pair of crew socks featuring the Doppler effect, the change in frequency of a wave (or other periodic event) for an observer moving relative to its source. This pair of crew socks comes with the following truism saying that will make others do a double-take and wonder exactly what you mean: "The Frequencies Of Life Are A Relative Matter". No need to be a physicist to enjoy this educational, scientific double-entendre!
