Lorentz-Fitzgerald contraction  
      n   the supposed contraction of a body in the direction of its motion through the ether, postulated to explain the result of the Michelson-Morley experiment. The special theory of relativity denies that any such real change can occur in a body as a result of uniform motion but shows that an observer moving with respect to the body will determine an apparent change given by a formula similar to that of Lorentz and Fitzgerald
