"This reversal from maximum compression to the beginning of expansion, and from heat to cold, and from charge to discharge and depolarization, is the most confusing of all phenomena in Nature to the physicist. It is the one thing all observers have missed. As we have mentioned before, even Einstein missed it in his Equation of 1905, for the validity of that equation ends right here and its reversal, which voids its validity, also begins right here. All observers throughout the centuries have failed to see that one direction of motion has produced a two-way effect, which is as applicable to a mathematical equation as it is to a state of motion."
