Turning the math into words is subject to interpretation (because it's _so weird_, it's not clear what it means; and I'm no physicist or mathematician either, but my understanding is...), but quantum mechanics seems to say there are physical laws actually limiting how precisely something can be known. Which is part of what makes it not just "what we can know based on measurement."

That is, a "truly omniscient being that would not have to rely on measurement" would apparently violate the laws of physics, is one thing quantum mechanics maybe seems to say.

"Thus, the uncertainty principle actually states a fundamental property of quantum systems and is not a statement about the observational success of current technology"
