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) although in certain titles elements such as falls cannot do this, and instead just leave the fighter with very low health. Since "Dead or Alive 2", the series has implemented its tag team fighting system, allowing characters to switch back and forth for combo attacks and even attack simultaneously when timed correctly. The tag mode also included special throws unique to certain pairs of characters and allows for the participation of four players, something not common in the genre. "Dead or Alive 3" introduced Attack Change, a new tag system feature where the fighting character can switch places with a
