The uncertainty principle

05/10/2008 11:34 PM

Have been reading and participating in several interesting forums lately dealing with the basic forces of the universe and the laws governing same. It came to mind that I had heard about a couple fairly new twists recently. One of them concerns the "uncertainty principle" and the other I'm not sure what it's called but to my mind it's something like the "observation principle" where the very act of observing a process changes it's dynamics.

So, what I'd like to know is: What do you folks think of these concepts and how do they effect the other universal constants we all hold so dear.

Hello Shadetree

Refer here: Heisenberg Uncertainty Principle

That'll get you started, then refer here:

The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.

Now you have something to get your metaphorical teeth into.

Cheers and Kind Regards....

But Sparky,

Why are you inviting a "metaphorical" argument when you know quite well the issue as to Heisenberg is that it speaks of reality, not metaphor.

That ought to be, is, more than enough room for argument.

Hello Jack Jersawitz

It speaks of "Reality as perceived".

Each observer's perception of "reality" may be different.

That's the "Uncertainty of perceived Reality".

Kind Regards....

Both the principles you state are correct.

We never know the factual behevior of the thing being observed. While observing, we do affect its behevior, though it is on micro level.

Also, what we observe is never certain. Next time we observe, it will behave little differently, for unknown reasons.

This we do experience in any measurement process also.

Alas, another day has passed, we sleep and awake to another take on a previous assumption. Its the subconscious at work and who is aware of what formulated processess take place there, of which we are unaware. The mind is always working on our behalf. on auto pilot,sorta.

I don't think the uncertainty principle is a principal in the sense of a principal of nature.

Rather it is a mathematical workaround in regard to a problem we as yet do not have the knowledge to solve. It is a conceptual workaround not a natural principle.

The second issue you mention has problems also in that it apparently is used to assert different things.

As far as the idea that viewing something, some process, may change the process, it seems that the claim is that the process is so sensitive that viewing it changes it's parameters.

I don't know if that is true.

But there is another claim that uses the same language. It is the statement that certain sub-atomic particles exist in a what has been called "super-position" and that upon viewing, the act of viewing causes the ultimate position to be determined.

That is the basis of the Schroedinger cat in the box mental experiment. The cat in the box is neither dead or alive until you open the box. I'm with Einstein, I don't believe a mythical god plays at dice.

The assertion seems to substitute for Bishop Berkeley's claim that none of this exists except that it exists as thought in the mind of god, that none of this exists, or has an actual final position, except as a mental act in the mind of the viewer.

The general problem I think underlies these issues is a lack of data hence we try to solve problems in our heads lacking actual physical data.

The completion of the Super Hadrian Collider in Cern later this year may help solve the data problem.

But the issue smells of another problem, i.e., the prevalence of the agnosticism of Kant and his unknowable thing in itself. There is talk of finding a unifying theory of all things. I think because of the prevalence of agnosticism they are missing the fact that the central unifying aspect of all of material reality is that it is always in motion. Motion is that unifier. The problem once you accept that is to determine the nature of the motion in each particular case and how it relates to other cases.

I am not a physicist nor a mathematician but I suspect that with a little thought, and the realization of how universal motion affects all things, they will solve the problem of the invisible dark matter.

Re: The uncertainty principle

actually the Heisenberg principle applies to all of life's situations -- being probablistic and relative to time - general relativity comes into play as well

for example in politics: we find as we phrase questions more specific, the answers become more irrelevant:

example: did you have relations with that woman?

Bill: that depends on your definition of is?

the classic example is Howard Baker in reference to Nixon; "What did he know and when did he know it?" how could anyone know both?

Probabilistically , we would logically assume that the answer to the question will be relative to the question extending the truth as far as possible to be plausible but minimally incriminating.

Closer to home example:

Wife: so exactly how many beers did you have?

Clearly the Heisenberg principle would apply to this case as normally the correct answer would be in a skewed distribution as the result of vague memory and the entropy factor to reduce the tension of the situation!

You too will now see the H principle at work all around you in your daily pursuit of the almost certainty of life liberty and happiness!

It changes nothing, people will believe in what they are taught, re enforced by good marks and opportunity. this is the definition of the uncertainty principle, you will go with the flow, whether deep down you believe it or not, if it turns you a profit, why not. Its a cynical age we live in.

There can be no doubt that in this world of reality, the uncertainty principle has more value, in everday living, than an outdated premise called the "Cosomosoligical constant. For what mind can expoliate its self into the realm of the infinite design and bring back from that formeless space, a concept of a universal concept yet undefined. God does not play dice, a famous man once said, i agree, that being said, the die has been cast, the problem is, is that, it has not come to rest, so we dont yet know what the result is.

Einstien was correct when he stated that everything was relative to the observer, and as we are aware each person holds his or her own point of view. so how do you put observation in logical context, the Hubble red shift?

Infinity is finite from a singular point of view, it finite in the sense that as better telescopes come on line, we can see further, thus expanding the finite toward the infinite,will we ever be able to approach the singularity, which travells at the speed of light, you have no need ror me to explain that.

what all i said has to do with the rotation of the earth, obviously i am not sure, so i will stop now, and go to bed.

I made an earlier observation on the quest stated and upon further delibiration, i return, as this is an intresting posting and worthy of further review. What perplexes me is the last question, which i would add a twist to, namely what is the other universal constants we all hold so dear.

What is this constant we hold so dear, it can only be one, if you have two or more, then by definition the point is moot. Because it is not coinstent within the framework hypotized.

The last question, dear sir, was asked, as it were, tongue in cheek.

I didn't realize I had been here before so I left that question to Sparky.

Nonetheless, now I realize how very accurate my question was.

What a mess!

Bye!
