The article seems to distill the concept of quantum uncertainty into this statement: there is an inherent uncertainty about what happens to a quantum system when we attempt to observe it Is this a good way to put it? I'm not sure if with "quantum uncertainty", they refer to the same thing as Wikipedias "uncertainty principle" page: https://en.wikipedia.org/wiki/Uncertainty_principle https://en.wikipedia.org/wiki/Uncertainty_principle The Wikipedia page sounds somewhat different (and harder to grasp) to me. It talks about predicting future states of pairs of physical quantities after knowing the initial conditions.
