Quantum superposition the eigenvector corresponding to the measured eigenvalue. It is natural to ask why ordinary everyday objects and events do not seem to display quantum mechanical features such as superposition. Indeed, this is sometimes regarded as "mysterious", for instance by Richard Feynman. In 1935, Erwin Schrödinger devised a well-known thought experiment, now known as Schrödinger's cat, which highlighted this dissonance between quantum mechanics and classical physics. One modern view is that this mystery is explained by quantum decoherence. A macroscopic system (such as a cat) may evolve over time into a superposition of classically distinct quantum states (such as "alive" and
Dead or Alive (franchise) "DOA3" and "DOA4" were released as launch titles for the Xbox and the Xbox 360, respectively. Some of the games, especially "DOA2" and "DOA5", were released in different editions and revisions. "Dead or Alive 5 Last Round" for the consoles is also available in the basic but free-to-play version "Core Fighters", lacking most characters and the story mode, that can be either upgraded to the full version or any additional content can be purchased selectively. A similar model is used in "Dead or Alive Xtreme 3". "Dead or Alive: Code Chronos" was the code name for a cancelled video game
