| + | <note important>For relatively obscure reasons Bohmian mechanics is quite unpopular and not well known. One contributing factor is that the originator of Bohmian mechanics, David Bohm, fell victim to the McCarthy era anti-communist witch hunt. Bohm fled to Brazil and became a tainted figure in the eyes of many. | ||

| + | Even today many of the older generation of physicists will tell you that Bohm's approach to quantum theory [...] is incorrect. In most cases it turn out that they haven't even read his papers and, when pressed as to the nature of the error in Bohm's approach, they will say that they don't actually know, but they do "know" that Bohm is wrong. | ||

| + | understanding the particle-wave dichotomy, with | ||
| + | its local and non-local aspects. It ran into difficulties | ||
| + | with quantum-field theory, but with new | ||
| + | ideas I think the difficulties can be circumvented. | ||

| + | <blockquote>What is not widely understood, even amongst physicists, is that a belief in the mystical aspects of the theory is a choice that one makes, rather than something inevitable. One formulation of quantum mechanics - long ignored or derided by just about everyone - which makes this particularly clear is the pilot-wave theory (also known as Bohmian mechanics, de Broglie-Bohm theory, the causal or ontological interpretation of QM). In this theory, wave particle duality is explained through the startlingly sensible notion of having both waves and particles (think about how that makes the double slit experiment intelligible!). So unlike in orthodox QM - where the wave function is all there is - the particles have an objectively real existence and they move along trajectories, guided by the waves. In such a formalism the standard paradoxes related to measurement, observation or wave function collapse (Schrödinger's cat, and so on) simply evaporate. The classical limit emerges out of the theory, rather than being presupposed. All the 'talk' is replaced by sharply-defined mathematics, it becomes possible to 'visualize' the reality of most quantum events, and - most importantly - the theory is completely consistent with the full range of QM predictive-observational data. | ||
