Can Uncertianty be Quantified?

[geckopelli]

If so, how? And if not, why?

 

I can handle a fairly complex science and/or math.

But, of course, the simpler the better.

It depends what you mean.

 

If you're talking quantum physics, then you're working towards the heisenberg uncertainty principle.

 

If not, you're looking at possible variation due to inaccurate tools.

[geckopelli]

Heisenberg it is.

dp x dx >:h:/(2x:pi:)

fafalone said in post #4 :

dp x dx >:h:/(2x:pi:)

That should be h, not :h:, since :h:=h/2:pi:

 

The relationship also works for dE x dT

[fafalone]

Plancks Constant is written as :h:

[geckopelli]

The "names" of the variables expressed as d, p and x?

No, it's written as h, but since the 2:pi: shows up a lot, :h: is useful.

 

e.g. E=h:nu: = :h::lcomega:

d is differential, p is momentum, x is position, E is energy, t is time

 

:delta:x:delta:p is how it's usually written, where :delta: is the uncertainty in the variable that follows it

Much thanks.
