Harvard Physicists Confuse Relative Speed with Proper Speed: Relative Speed vs. Proper Speed (en Inglés)
Reseña del libro "Harvard Physicists Confuse Relative Speed with Proper Speed: Relative Speed vs. Proper Speed (en Inglés)"
Harvard physicists (and all other relativists) confuse relative speed with proper speed. Here is the explanation: Proper speed (author's term/definition) is the distance a uniformly-moving object or physical phenomenon (such as sound or light) covers per given unit time in a given inertial environment/system. By nature and definition, proper speed is constant independently of the motion/position of observers. That is, proper speed is observer-free or observer-independent. Relative speed (author's definition) is the rate of change in distance between two specific objects- an observer and a target object, for example. Even if an object is in uniform motion (=proper motion) in a given inertial system, the speed of the object "relative" to a specific observer may change depending on the motion/position of the observer. That is, relative peed is observer-dependent. For example, if an observer sits on the line of motion of a uniformly moving object, the speed of the object relative to the observer (or vice versa) is constant. However, if the observer sits off the line of motion of the same object, the relative speed between the two is no longer constant but changes continuously as the object moves. This phenomenon, which is new (!) to most physicists, is consistently confirmed by radar (speed gun or speed detector), calculus, and trigonometry (cosine effect). (See Chapters 4-8.) Einstein thought that all motion is relative and thus all peed is relative; he did not have the notion of "proper motion" and "proper speed," which is observer-independent. (Einstein did not use the term "proper speed" itself.) Worse still, what Einstein took for relative speed was proper speed, which was observer-independent (see Chapter 7). The concept of isotropy of light speed came from confusing relative speed with proper speed. With this and many other fundamental misconceptions (see all the chapters of this book) Einstein distorted the concepts of speed, space, time, acceleration, inertia, gravity, mass, energy, and everything else. Physics is dead. How in the world can observer-free speed (=proper speed) be relative speed? The author demands that Harvard physicists give their official answer to this question. Readers should not confuse relativists' terms "relative speed," which is incorrect in meaning, with the author's term described above. Relativity is the confession of relativists that they do not know what relative speed is.
