I found the article in the Guardian about Schrodinger's cat theorem wonderful. It also promoted many amusing comments.
By 1925, then a professor of physics at the University of Zurich and holidaying in the Alps, Schrödinger formulated a wave-equation that accurately gave the energy levels of atoms. It formed the basis of the work that would earn him the Nobel prize in physics in 1933.
In subsequent years, he repeatedly criticised conventional interpretations of quantum mechanics by using the paradox of what would become known as Schrödinger's cat. This thought experiment was designed to illustrate what he saw as the problems surrounding application of the conventional, so-called "Copenhagen interpretation" of quantum mechanics to everyday objects
