(that is why i say that wrong understanding of the above phenomenon- is very harmful for further advance of science !!! especially the self smugness of some parrots or crooks ??( the old 'witch Doctors ???(:-)) ATB Y.Porat ----------------------- ATB Y.Porat -------------------------

The photon wave exits the slits and creates interference which alters the direction the photon 'particle' travels. If you want to consider that to be 'interfering' with itself then go right ahead, but there is a physical wave propagating available paths and a 'particle' traveling a single path. There is not a 'particle' traveling multiple paths. > yet it can be asked about other physical phenomena as well > > TIA > Y.Porat

The philosophiocal speculation upon the "shape of reality" vs. the "alienity" of human observations as related inevitably to it is by far more intriguing than getting astonished for the presumed offense to "ortodoxy" of science. Philosophy not Science is the true tool on the long and troublesome road towards "trascendence" of the marginal limits of our "rational" patterns. Our logic shall constantly "invent" new paradigms suited to give "rationality" to our expanding capacity of introspection upon the Reality! I've met physically both Bohr and Heisenberg and guys such as Per Bak and Renè Thom and gave up to devote my efforts to "experimental physics"! Most of the 1900 Nobel awards have been delivered to "experimental" discoveries that were mere "proof" of forecasted phenomena proposed by real scientists decades before! The age of Galilei, Faraday, Einstein, Bohr, Prigogine is still alive under the label "phylosophy" while "physics" is ate best represented by guys like Lorentz, Fermi, Oppenheimer or ....
