Radio waves vs light waves

"Jim" wrote in message
Ok, here's another weird one... if light is supposed to be made up of both
waves and particles, how much does it weigh?

It is my understanding that light is not "made" of waves or particles but
waves or particles can be used to describe their behavior depending on how
one wishes to observe them ("wave/particle duality", I think it's called).

Then again, if you observe the wave/particle, your observation changes the
outcome of the observation. This is called the "Ya Just Nevah Know" theory.

Weird stuff, that physics.

But here's another one that I got from a book a friend form here mailed to
me some time ago: You are inside a perfect sphere that has a mirror
surface. Your eyes are squarely (or is it"sperely") in the middle of the
sphere. What does the reflection look like?

It looks like the sound of one hand clapping.

Also known as the Heisenberg Uncertainty Principle.

Computer bugs that only happen when you disable your debugging tools are
therefore known as "Heisenbugs."


Scrawled on a toilet stall at Caltech sometime in the early '80s:

"Heisenberg sat here yesterday."

Then, in different handwriting immediately below:

"Pauli was here at the same time."


I'll explain it anyone wants, but Teacherjh seems to be doing a better
job with explaining this stuff that I probably could.

I was there. It goes:

"Heisenberg might have been here."
"Pauli was here too, but not at the same time."

It refers to the Heisenberg uncertanty principle (one can measure the position
or momentum of a particle, but not both at the same time (*)), and the Pauli
exclusion principle (no two electrons (**) can be in the same state at the same
time)

(*) You can measure them both, but the more accurately you measure one, the
less accurate the other is. It's not too farfetched to say that the concept of
a particle having a precise position and momentum at the same time is
meaningless.

(**) Not just electrons, but an entire class of particles (called Fermions)
behave this way. Common fermions are electrons, protons, and neutrons.
Compare with Bosons, which like to be in the same state. Photons are bosons,
which is why a laser works... all the light waves can line up in step. An
electron laser would be impossible (or would lead to a huge physics advance)

All this is related to aviation in that thinking about it makes one high. g

Not true. There used to be great herds of bosons, and they would roam
across several states in the great plains. They're gone now.

Nope. They are in Washington DC. All in the same state. The state of
confusion.

John,

But now, the Bozos roam there.
