[extropy-chat] FWD (SK) Heisenberg's Uncertainty Principle

[Giu1i0 Pri5c0]

I would not use any of these two statements to "explain" HP. Rather, I would
start by recognizing that thinking that what we observe as an electron must
have definite position and velocity is an assumption, an assumption that
experiment proves wrong. In the quantum world at a fundamental level,
position and velocity should not be used as building blocks of our
description of the universe.
What should be used instead? Now, I hope someone can answer that.

Subject: [extropy-chat] FWD (SK) Heisenberg's Uncertainty Principle


Can anyone here (especially someone with physics credentials) give me a
good layman's explanation of Heisenberg's uncertainty principle?

When I do a web search, I get some sites saying that we simply don't
have the tools required to view delicate sub-atomic structures without
disturbing them. One page claimed that, for instance, observation
requires light, and photons striking the subject disturbs it.

However, some other articles assert that it is the act of human
observation, no matter what technology we use, which affects the
outcome. This interpretation is favored by mystics, who claim it is
proof that reality is subjective.

Any help on this would be very much appreciated.
