Light: Speed of Light:
“Einstein was much purer than Planck in just taking the speed of light, which was a constant figure. It was demonstrated in a vacuum tube, linearly. Therefore, light-- as all candle power does-- goes in all directions, not just in a line. Therefore we know that the surface always grows as the second power of the linear. So the speed of light is c-- use small c for any radiation, the speed of any radiation omnidirectionally… because a wave of light is going in all directions. Therefore it is c to the second power.”
