Iceland Spar

Filed under: Uncategorized — basileios @ 4:23 pm

Iceland Spar goes strong as part of the splitting/duality metaphor which is more than prominent throught the pages. The Michelson and Morley exp[eriment which was introduced earlier also uses split light technique for measuring the difference in the speed of light in two directions.

  1. As for the Michelson expriment, Pynchon says on p. 59 that it was first carried out in Berlin. This is not completely correct: he first tried it there at the Institute of Physics but there was too much noise due to traffic so the interferometer did not produce any results.
    Therefore, in 1881, Michelson moved to the Astrophysical Observatory Potsdam on Potsdam’s Telegraph Hill where he succeeded finally for the first time to show the Null event: no ether out there.
    In the basement of what is now Building A31, at the very place where Michelson had set up his experiment one can find a reproduction of the instrument though – for health reasons – without the original quicksilver lamp.
