assistant: Richard Meic discussing "Cat in the Box"
with me...
What ideas? You've totally misunderstood the "cat in the box" scenario and
drawn (incorrect) conclusions from your misunderstanding. All that one can
glean from that is that you don't have a clue about the subject matter but
think that you do.
Your point of view amounts to a discussion about apples when everyone was
discussing sheep.
What does, though?
Even cutting edge physicists are not sure of this so how comes you are?
Incorrect. An atom is a system and not a quantum particle. Sub-atomic means
_smaller_ than the atom.
The uncertainty principle says that we cannot know with finite precision both
the position and momentum of a given sub-atomic particle simultaneously. The
more precision we want of the position the more we have to sacrifice
precision in its momentum and vice versa. We can get results for its position
and momentum but both results would be only 50% accurate at most.
That is because there is a different kind of looking involved. When we look
with our eyes we are seeing the light that hits our retinas. In the
sub-atomic realm we can't use our eyes directly so we have to use detection
equipment. This detection equipment alters the outcome of the experiment and
in unexpected ways (although they are not so unexpected these days as QED can
predict the outcomes with high probability).
Why don't I believe you Richard?
You are indeed correct. However, if you post things that people disagree with
in a public echo then you should expect people to speak up and explain why
they think you are wrong. You would do no less I presume?
However, what I get from you is that you've already made up your mind and
no-one is going to change it. Hardly an open mind.
