c = h = epilon_0 = k_b = 1 (Unit Systems) |
[Note: c is speed of light, h is Plancks constant and k_b is Boltzmanns
constant]
Another modern unit system would be possible. By adjusting the units for
distance, the unit for energy, the unit for charge and the unit for
temperature, it would be possible to somehow siplifiy the units in physics.
Someday this will come (I'm sure), but so far this 'modern system' would
probably be to confusing for most people. -But it's still an interesting
issue, I think...
Should we introduce a new unit system someday? -Then we can use c=1 in all
problems in relativity, and again other and simpler units in most areas of
physics. -After all, the four areas of units mentioned in this posting are
defined more or less random. -Could 's', 's^-1' and electron-units instead
of Coloumb be usefull? -And could the unit for temperature simply be
converted to units of energy?
Probably units of 'second^-1' (energy or frequency) for temperature would be
to confusing to most people. But as the understanding of the science of
pysics is developing, someday such things will probably come.
-That's just my opinion...

Even Wilson finally managed to understand it, but since

he will never understand the concept of closing speed.
Fantastic :-)

What is this?
Some kind of quote of some post?
An introduction to the ***** you produce later on?
***** that you expect someone will bother reading?
We can smell it from here.
Your pathetic stupidity IS fantastic, I agree, local village dog *****.
Wilson understands "relative", you do not.

Speed of light relative to what?
Question to Androcles: Have any man, no matter his position or his
velocity, ever measured other values of the speed of light than the
usual 299,792,458 m/s? -If you have a reference of that, and can
explain it, please let us all here in sci.physic know about it.
My only mistake in this posting: k_b should have been k_B (as the 'B'
is from Boltzmann which is a name). :-)

Yes.
We've always measured a range of velocities for light, you just haven't
realised it.

Doppler shift say it all.

How many meanings to PHYSICS can there be?
Alice then went back to say "The term *curvature* basically applies to
the bending of curves and 2-d surfaces."
Ho ho, thought Humpty Roberts, "Not in differential geometry or GR.
The term "curvature" was borrowed by analogy with 2-d surfaces, and
has come to mean the Riemann curvature tensor. That is, a manifold of
_any_ dimension with nonzero Riemann tensor is said to be curved."
and he shrugged like this :- "<shrug>"
Alice asked "Why *said* to be curved when it is actually not curved?"
Humpty Roberts let out a great sigh.
" <sigh>", he said.
"The nuances of English. I was discussing the usage of words and
not the concepts they represent."

The end.

Here's another gem from the shrugging prat Humpty Dumpty Roberts:

Now you know what speed is, it has been elaborated upon by the genius,
never mind that we've all either had or come close to having a speeding
ticket at some time, and have crossed time zones.
And you don't think Roberts is a total prat? Do me a favour, he's as much
use as a tit on a bull.

Another modern unit system would be possible. By adjusting the units for
distance, the unit for energy, the unit for charge and the unit for
temperature, it would be possible to somehow siplifiy the units in physics.
I suggest 'Einstein' (E) for energy, 'Maxwell' (M) for charge,
'Boltzmann' (B) for temperature and 'Lorentz' (L) for time...
A new and better unit for distance is probably also needed...
NU (New Units), but when? -The SI system isn't an intelligent system.
