Schrödinger's cat Schrödinger's cat Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat that may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur. The thought experiment is also often featured in theoretical discussions of the interpretations of quantum mechanics. Schrödinger coined the term "Verschränkung" (entanglement) in
Dead or Alive Ultimate Sega Saturn version, and is generally considered more of a collector's disc than for its content. "Dead or Alive Ultimate 2", being a remake created after the debut of "Dead or Alive 3", takes elements and mechanics from both its original iteration and successor. The action of 3D-axis movement is as free-formatted as "DOA3", and Hitomi is now a playable character albeit outside story mode. Other elements have been kept intact from "DOA2". These include higher damaging counters than in "DOA3", environmental hazards not warranting a knockout on a character, and a counter mechanism that is much harder to execute.
