• Physicists normally distinguish two main categories of energetics: potential (static) energy, and kinetic energy, which causes movement. Perhaps we might now need to add a third category: kinematic energy, energy resulting from the effect of movement, and its varying speed, on ocular, optical or optoelectronic perception.

• The space of sight is accordingly not Newton’s space, absolute space, but Minkovskian event-space, relative space. And it is not only the dim brightness of these stars that comes to us from out of the distant past, out of the mists of … Continue Reading
