what Heisenberg grasped—what he calculated mathematically, yes, but also what he was able to capture in language—was that to simultaneously observe an electron’s position and momentum would require a perfect presence in a single moment in time, which is utterly incompatible with the minimum condition of observing anything at all. Not because of som

“It is impossible to design an apparatus to determine which hole the electron passes through, that will not at the same time disturb the electrons enough to destroy the interference pattern.” If an apparatus is capable of determining which hole the electron goes through, it cannot be so delicate that it does not disturb the pattern in an essential
