As a retired physics teacher and a new trombone player I'm
confused
as
to why a larger bore trombone requires so much more air to
play
than
a
smaller bore trombone. Isn't the horn full of air even before
it
left
the case? Isn't the player simply setting up standing waves
in
the
air
column? Where does the extra air go?

The speed the air passes the object that make the "noise" is
what
is needed.
A larger bore would need more air flow to produce the same
speed.

Sam? That's a little over the top?

Sam can not attack my post. so he attacks me as usual.
The website (www.crank.net) is just an anti-anti-relativist site.
:)

Having said that, your web does include the line:

"Physics that include zeros doing things or having energy are
bologna.
such as Zero Point Energy [...]"

Do you know what zero point energy is?

Yes, It is a bogus theory that belongs in the trash bin
along with photons that have 0 mass but have momentum
Saying there is a limit to "small" and calling such small a 0
instead of what it actually is shows a big lack of "physics" in
physics.
It is like the same as calling germs not there because we could
not detect them yet.
It is a repetition of history only and such repetition is a joke.

:)

No, it's lowest energy point in s system. It doesn't mean it has zero
energy - which in a bizarre sort of way, seems to be what you are
saying.

Yes, basically.
:)

See http://www.casimir.rl.ac.uk/zero_point_energy.htm
& http://www.fnal.gov/pub/inquiring/questions/vacuum_energy.html

An electron is simply a gathering of "even smaller" stuff.
As we increase technology, we may even be able to find
even smaller parts of this stuff.
Just as with germs long ago, just because we can not
measure something there, does not mean there is nothing there (zero)
and when we see things occur from this nothing there (zero) is it not
proof there is something there?
:)

Actually I wondered, coming from a colloid background, how the Casimir
effect compares to Ostwald Ripening or the Gibbs-Thomson effect.

Again it comes down to the "smaller than we can see (detect)" stuff.
If we can only detect an electron when is it doing something,
how can we detect an electron that is "not doing anything" until
it does something and of course, the same goes for the "even smaller" stuff.

As I stated zero point energy is bologna.
It is a bad name and the term zero is like removing
the physics of what is actually there.
Might have well called germs long ago,
zero point sickness.
:)

Well, it's just a name - what would you call it considering that all
matter has been removed to form a vaccum? Vacuum Energy?

If the energy is coming from radio waves or gamma rays or etc..
It should be called wave energy.

A vacuum can not shield itself at all.
So even vacuums must have waves passing through them
especially for such stuff like light passing through.
Wave energy makes more sense and would stop the
sometimes thoughts of a zero point energy impossiblity.
after all if E = 0 truly, you have no energy at all and
the point itself would not even be a mass nor an energy.
