Schrödinger's cat regard the "alive and dead" cat superposition as quite real. Intended as a critique of the Copenhagen interpretation (the prevailing orthodoxy in 1935), the Schrödinger's cat thought experiment remains a defining touchstone for modern interpretations of quantum mechanics. Physicists often use the way each interpretation deals with Schrödinger's cat as a way of illustrating and comparing the particular features, strengths, and weaknesses of each interpretation. Schrödinger wrote: Schrödinger's famous thought experiment poses the question, ""when" does a quantum system stop existing as a superposition of states and become one or the other?" (More technically, when does the actual quantum state
Dead or Alive 2 create a physics engine dedicated entirely to the animation of the female characters' breasts. "Dead or Alive 2" used the song "Exciter" by Bomb Factory in its opening sequence. Also used as a background track was "Deadly Silence Beach" and "Clumsy Bird". Both tracks can be found on the self-titled mini-album "Bomb Factory" and on the "Dead or Alive 2 Soundtrack". Two soundtrack CDs were released in 2000 by Wake Up in Japan: "Dead or Alive 2 Original Sound Trax" (KWCD-1001) and "Dead or Alive 2 Original Sound Trax" (KWCD-1004). Several Japanese guide books for the game were published by
