The specific example of an electron orbiting in the field of a charged sphere and a superimposed uniform magnetic field is used to illustrate that in classically chaotic systems, irreducible uncertainties required by the Heisenberg principle are amplified exponentially to the macroscopic level in short times. According to the Copenhagen interpretation of quantum theory irreducible quantum uncertainties have led to quantum indeterminacy on a macroscopic scale in interesting times.
