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 2 remake of "DOA" and "DOA2" for the Xbox with a greatly improved graphics engine. As it was created after "Dead or Alive 3", it 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, as well as Tengu are now playable characters (albeit outside story mode), but other elements have been kept intact from "DOA2". The biggest set of changes instituted in "Dead or Alive Ultimate" are online play over Xbox Live and the inclusion of slopes, which are a type of environmental hazard. Dead or Alive
