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
P-adic quantum mechanics wave functions, in which case the problem of the probabilistic interpretation of the "p"-adic valued wave function arises. As there does not exist a suitable "p"-adic Schrödinger equation, path integrals are employed instead. Some one-dimensional systems have been studied by means of the path integral formulation, including the free particle, the particle in a constant field, and the harmonic oscillator. P-adic quantum mechanics p"-adic quantum mechanics is a collection of related research efforts in quantum physics that replace real numbers with "p"-adic numbers. Historically, this research was inspired by the discovery that the Veneziano amplitude of the open bosonic string,
