I don't understand this comment - Interference fringes are produced only when two electrons pass through both sides of the electron biprism simultaneously. This is different than Young's double slit experiment with photons.
From the linked article, it looks as though the electron biprism is a more complex version of the double slit. I suppose the same question arises, though. Interference occurs only when something passes simultaneously through both slits, or on both sides of the electron biprism. So what is the something? Is it a bi-locating particle, or a wave? Personally, I would go for the wave, but I'm just a hitch-hiker.
Would you agree that the article could very easily give non-experts (at whom it is obviously aimed) the impression that an electron can be in two places at once?
