Space-Time in Quantum Theory

Max Born, not Werner Heisenberg as is usually assumed, created the original version of Quantum Theory, «Matrix Mechanics». The fundamental laws, commutation relations and quantum equations of motion, resulted from Born’s recognition of the basic principle of quantum physics: To each change in nature corresponds an integer number of quanta of action h. Action variables may only change by integer values of h, requiring all other physical quantities to change by discrete steps, «quantum jumps». The mathematical implementation of this principle led to commutation relations and quantum equations of motion, published by Born and Jordan in September 1925. Most importantly, the classical notion of «time», as one common continuous time variable and nature evolving continuously «in time», has to be replaced by an infinite manifold of transition rates for discontinuous quantum transitions. The notion of a point in space-time looses its physical significance. Quantum uncertainties of time, position, just as any other physical quantity, are necessary consequences of quantization of action. The essential differences of Born’s discontinuous quantum physics to the standard interpretation, relying on classical space-time concepts, will be described.
