(in understatement because he is dishonet as well - while a real scientist cannot be dishonest !!) being honest is one the differences between science and Politics !!!)

He, and perhaps some of you, cant fathom that simple logic can invalidate many of those. The most common error in many equation types, is to allow the units of proportionality factors to be included in the units of the results. The interesting TV show, MythBusters, enjoys crashing things or hitting things. I was amazed to hear those guys state that the calculated forces of impact are such-and-such foot-pounds. Foot- pounds? The latter is, actually the term for MOMENT, or the tendency of a force to cause a rotation about some fulcrum or point of pivot. The laughable units for MOMENTUM thats shown in many textbooks is: pound-feet/sec (sic). That might be logical, because momentum is = mass times velocity, or mv. However, the v, in this case, is part of a proportionality fraction that becomes unit-less. To explain: If a mass, like say, a 250 pound linebacker, has a velocity in some direction, and you are standing in his path, you will be hit by a force. Since that force is dependent on how heavy the linebacker is, and how fast he is moving just before hitting you, then the correct way to write the equation for momentum is F (or force) = mv. In many texts, the letter p is substituted for force or reactions. In fact, the letter p is used in all of the beam analysis equations in the AISC Steel Handbook that must show a point load or force. When I told PD that the equation for momentum is F = mv, stated in POUNDS, he accused me of lying. Because pwhich means FORCE, fis different alphabetically PD supposes that momentum must be a different animal than force. But, as usual, he is wrong! Newtons second law states: A continuous, uniform forcewhen applied to a frictionless and unrestrained bodywill accelerate the body in the direction of the force, and in proportion to the force. The equation for Newtons law thats usually shown in texts is: F = ma. The momentum formula, thats in the above paragraph, is a close cousin to Newtons when it comes to measuring the force of impact, because the aspect of acceleration which quantifies the expected force to be delivered is the instantaneous VELOCITY right before the object (like the 250 pound linebacker) impacts. A 250 pound linebacker traveling 8 feet/second (1/4th of the g velocity increase) will deliver a force (f or p) of 62.5 pounds. That would be exactly how hard a 250 pound linebacker would hit if he was accelerating 32 ft./sec. for ¼ second. A proviso is that he not continue to accelerate once the other player is impacted. Since kinetic energy is the force-delivery potential of falling objects, as well as for objects traveling at any set velocity, Ive determined that KE and momentum are interchangeable terms, with THIS important exception: Objects that are RESTRAINED, but being acted on by a potentially propulsive force, will have the latter propulsive force ADDED to the force of impact. My mathematically and experimentally verified formula for kinetic energy is: KE = a/g (m) + v / 32.174 (m). The a/g will be 1 for objects being acted on by Earth gravity. So, the KE of objects being restrained prior to release is already one weight unit, even before any downward motion happens! The v / 32.174 (m) is the same unit-less PROPORTIONALITY factor that is in the momentum equation. Heretofore, the masses were required to be converted to SLUGS (32 pounds) in order to find the force. My velocity-variant fraction is more intuitive and doesnt require an explanation of usage below the equation. It is the omission of the conditions of usage, or applicability, that cause the proliferation of errant equations. The way I was able to master equations was to express what those say in clear English. When different users of equations have different ideas what the variables and the constants mean, there can be big trouble. In most cases, my New Science will make the equations simpler and more intuitive. Does anyone, other than PD, fault that?
