Scientific theory
In 1905, Albert Einstein published the principle of special relativity, which soon became a theory. Special relativity predicted the alignment of the Newtonian principle of Galilean invariance, also termed "Galilean relativity", with the electromagnetic field. By omitting from special relativity the luminiferous aether, Einstein stated that time dilation and length contraction measured in an object in relative motion is inertial—that is, the object exhibits constant velocity, which is speed with direction, when measured by its observer. He thereby duplicated the Lorentz transformation and the Lorentz contraction that had been hypothesized to resolve experimental riddles and inserted into electrodynamic theory as dynamical consequences of the aether's properties. An elegant theory, special relativity yielded its own consequences, such as the equivalence of mass and energy transforming into one another and the resolution of the paradox that an excitation of the electromagnetic field could be viewed in one reference frame as electricity, but in another as magnetism.
Ricardo Carezani
However, after the setbacks in the 1980s, Carezani regained some prominence in the 1990s and 2000s. In 1991, he discovered a mathematical conversion theorizing that special relativity is a subset of autodynamics. Despite a heart transplant in 1992 stopping any research for the next year, Carezani regained momentum and founded the Society of the Advancement of Autodynamics, a California-Based organization now run by David De Hilster. In 1996, Carezani was presented the "Lifetime Achievement Award" in relative physics, and he published his first book one year later.
