One recent experiment backs up Minkowski's answer — but still may not prove Abraham wrong. One might expect that the momentum of a photon, under almost any conditions, would no longer be a ...

This experiment measures parity-violating elastic scattering from the proton at a momentum transfer Q 2 = 0.1 GeV 2 ... Since the Z 0 boson (unlike the photon) couples mainly to neutrons in a nucleus ...

Traditionally, textbooks teach us about vertical optical transitions, where a material absorbs light with the photon changing ...
