"Uncertainty" suggests that the position might, in some way, be defined with 100% precision, but it's us, the observers, who are uncertain what the actual value is.
"Unschärferelation" suggests the value coming out of the system (position, impulse, etc) is in a fundamental way not pinned on a single value fixed with 100% precision, but instead it's spread out over a distribution function.
- EnFinlay 10y agoOh, I got it. It's the difference between "I am uncertain" and "It is uncertain". That makes sense. First discussion that happens in an undergrad quantum mechanics class. Teacher: "It is uncertain" Student: "Can't we measure it better?" Teacher: "No, it is unknowable, no matter what" Student: "Wtf?"
