One person writing equations got confused with all his equations about force, momentum, and other principles. Acceleration is NOT velocity squared. This person obviously never had even an introductory course in calculus. You can probably guess the reason for the label. If you never had calculus, it is easy to see how one could confuse the nomenclature for a derivative with the nomenclature for the squaring of a variable.
Force is mass times acceleration.
Kinetic energy, however, is represented by half the product of mass and velocity squared. Etc., etc., etc. The stupidity of the quantum physics discussion doesn't even merit comment. At least it's entertaining. Another interesting argument I find amusing is the one about all the old masters who never weight trained, but they were sooo good.
