What is theory of Uncertainty? Please explain?

Answer 1

If you are talking about Quantum Physics:

The Uncertainy Principle explains that particle like electrons are not points or waves, but a combination. If you try to measure an electron, this characteristic means that you can not know both i exact location and its exact momentum simultaneously.


If you are talking about Probabilty:

It means that events, like the flipping of a coin of the tossing of a die, have multiple results possible, and the chances of each result occuring can be calculated.


If you are talking about Chaos:

Its the notion that tiny changes will actually multiply to become big differences in a result, instead of tiny changes just cancelling each other out and disappearing. The famous description is the Butterfly Effect - while you would think that a butterfly flapping its wings would just be cancelled out by the wind, maybe what really will happen is that by flapping its wings, it made enough of a tiny chnge that kept growing until finally it resulted in rain in China (a doubtful result, but descriptions need to be dramatic).

Answer 2

The chaos theory - it pretty much states that the outcome of a certain event is unpredictable.
I personally think that if ALL of the necessary data for cause is known, the effect will be be predictable - sometimes, however, in the real world, there is just too much data, the necessary data isn't known or the cause is just too complex, hense, the theory of uncertainty.

Answer 3

Uncertainty is the opposite of certainty, certainty is the opposite of doubt, doubt = uncertainty and both are the motivation of all science. Therefor the formula for the theory is, U+D= M.

Answer 4

Heisenburg's uncertianty principle puts a definate lower boundary on how good our measurements can possibly be. It can be seen in many factors associated with physical scientific research today, where peaks of higher energy get spread out over longer times, same with momentum distributions getting larger and larger. To say that this is annoying is really an understatement. It gives an aura of probabilistic nature to all fundemental particles, and makes it extremely hard to see particles, when our signatures measure the signatures of several different particles, and they overlap.

Put one way, the uncertianty principle can be described in one sentence. "All of God's toys are here, we're just not allowed to play with some of them."

Answer 5

In very basic terms, the Uncertainty Principle states that you may precisely locate a sub-atomic particle, but you can't determine its velocity at the same instant. Or if you can precisely determine its velocity, you can't specify its location at the same instant.

Answer 6

You are more certain of where something is...like use more light to see it., or a ruler to measure it, the more uncertain you really are where it is.

somehting like, the more you use something to measure where something is, the more you move it away w/ whatever you used to measure it

Answer 7

Well Art, I'm uncertain.
