 Special relativity (Site not responding. Last check: 20071020) 
  The theory, known as Lorentz Ether Theory (LET) was criticized, even by Lorentz himself, because of its ad hoc nature. 
  While Lorentz suggested the Lorentz transformation equations, Einstein's contribution was, inter alia, to derive these equations from a more fundamental theory, which theory did not require the presence of an aether. 
  Under Special Relativity, the seemingly complex transformations of Lorentz and Fitgerald derived cleanly from simple geometry and the Pythagorean theorem.
