De Broglie and David Bohm found a method (1952) that explains the double-slit experiment and its variations, which are so central to QM, in an intuitive way without appeal to probability, wave-function collapse, the "measurement problem", or invoking the consciousness of the experimenter. Although recognition of Bohm's work was not timely for sociological reasons, John Bell praised it as early as 1987.
I can almost understand that the experimental configuration can determine a nonlocal equation that guides the path of particles through the apparatus, such that blocking one slit causes the interference pattern to disappear, but I don't understand at all how detecting which slit the particle went through (in such a way that the motion of the electron is not disturbed) can also cause the pattern to disappear. Can someone please try to explain this latter effect, using the Bohmian interpretation, and using a minimum of mathematics?
In Bohm's 1952 paper, part I, page 174, he says that measuring which slit the particle went through (WWM) disturbs the trajectory of the particle, causing the pattern to disappear. He further says that being able to measure WW without disturbing the particle would cause the interference pattern to be seen. This, however, is not what is observed in actual experiments.
