Dear All,

I was wondering if anybody could help me, I am a first year
undergraduate Mechanical Engineering Student at the University of
Exeter and i am lookng for a good clear explanation of Heisenburg's
uncertainty principle. Preferably on the internet as i am a student i
don't have much money!! I would be extremely grateful for any info at
all!

Also if anybody knows of any information on the construction/design or
theory surrounding a Pelton Wheel I would be extremely grateful

Thanks

Rob

I used to believe in Heisenberg, but now I'm not sure.

To Rob,

Heisenburg's uncertainty principle states that; if you know the position of
a relativistic particle you can't be sure at what speed and in what
direction (velocity) it is traveling. Alternatively, if you know the
velocity of a relativistic particle you can't be sure of its location.

The above came about because relativists did not realize that relativistic
particles follow a helical path as they travel through space. Therefore all
helical wave particles behave both like a particle and a wave, without the
need for a medium (ether) to travel through. Consequently each individual
relativistic (helical wave) particle has a frequency, a wave-length and an
amplitude.

For a more complete explanation, see the first of my Selected Papers titled:
'Helical Particle Waves' which you will find at:

Enjoy, Len.

I'm not sure where to find an explanation, but the explanation is
simple, at least heuristically. First of all, it is more accurate to
use the term ``indeterminacy'' than ``uncertainty.'' There is nothing
uncertain about the values you measure. Second, For any physical process
which is finite, there is only a finite amount of information to measure.
If you list the possible mesurements you can make, only a subset of those
measurenents will be required to extract that information. Once you
specify a particular subset, other measurements will either be redundant
or incomensurate with the measurements you've made. Heisenberg's
principle tells us which measurements are mutually incompatible and which
are not. Essentially, two measurements are considered incompatible if
an arbitrarily precise measurement of both would permit you to obtain more
information about a system than there is to obtain. You can think of
it similarly to counting bits. Regardless of how to try to divide N
bits, there are only N bits to count. More formally, the quantities
you can measure are called observables in quantum mechanics. Observables
are represented by hermitian operators. (You can think of an operator
as a particular type of matrix). So if you have two operators, A and B,
a measurement of both A and B is the combination AB or BA. If AB and
BA differ by a factor of i\hbar, the two measurements are incompatible
and a precise measurement of one, necessarily leaves the other
indeterminate. Two measurements are only compatible if AB - BA = 0.
(Tell me if you want a more formal explanation. I tried to provide a
physical picture of what the uncertainty principle means rather than
a technically rigorous explanation and derivation.)

No, that is not what the uncertainty principle says. Do you really
think you're being ethical by responding with a completely incorrect
answer as a pretense for directing people to your crackpot articles?

To Androcles,

The mechanical oscillator has a sinusoidal frequency and amplitude, but not
a wavelength, since it is stationary.

If this oscillator produces a sound, its wavelength will be the speed of
sound in air, divided by its frequency.

I can't move it, Len? Why not?
What is the wavelength of the oscillator if I put it in my car?
What is the wavelength of the oscillator if it IS my car?
After all, my car is a mass on 4 springs, I can remove the "shock
absorbers" that do the damping.
