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 5 as several new stages and fighters (including "Ninja Gaiden"s Rachel and Momiji, and "Virtua Fighter"'s Jacky Bryant, as well as the return of "Dead or Alive 2" characters Leon and Hayate's amnesiac karateka identity, Ein), and all-new features such as two-on-two online multiplayer tag team battles, among many other changes. Three new female characters: Marie Rose, Phase-4 and Nyotengu, joined the game's roster in 2014. A free digital version, titled "Dead or Alive 5 Ultimate: Core Fighters", which features four playable characters and the online mode, with additional characters and story mode content available as purchasable downloadable content, was released
