‎First printing of these importent papers on the philosophy of Quantum physics. ""If we have to go on with these damned quantum jumps, then I'm sorry that I ever got involved."" (E.Schrodinger).""In it he contrasts the smooth evolution of the Schrodinger wavefunction with the erratic behaviour of the picture by which the wavefunction is usually supplemented, or 'interpreted', in the minds of most physicists. He objects in particular to the notion of 'stationary states', and above all to 'quantum jumping' between those states. He regards these concepts as hangovers from the old Bohr quantum theory, of 1913, and entirely unmotivated by anything in the mathematics of the new theory of 1926. (J.S. Bell).‎
