An analysis has been performed of the theories and postulates advanced by von Neumann, London and Bauer, and Wigner, concerning the role that consciousness might play in the collapse of the wave function, which has become known as the measurement problem.
giving out or weakness of the knees can have different causes. These can include problems outside the knee joint itself (weak muscles for example) or inside the knee (torn ligaments or cartilage). See an orthopaedic surgeon to address your individual problem.
Patient : About two weeks ago my knee has started to give out randomly when walking. When it happens I just kind of collapse onto the other leg. There is no pain in that knee and it has never been injured. The other knee has begun to ache but im assuming its from catching me numerous times over the past few weeks.
