Special relativity (alternative formulations)
Hendrik Lorentz and Henri Poincaré developed their version of special relativity in a series of papers from about 1900 to 1905. They used Maxwell's equations and the principle of relativity to deduce a theory that is mathematically equivalent to the theory later developed by Einstein.
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.
