I happen to agree with your fundamental philosophy, but when you state
velocity is independent of time when clearly everyone uses miles per hour,
'hour' being a unit of time, you are totally off your rocker.

Androcles


Don't be hard on Len. He has some excellent ideas.

Len is not completely wrong on that last one, A.

Consider a spaceship that fires its engine at a constant rate for a period.
You can say that its velocity is changing as a function of time WRT an external
point, such as its base. But to the ship's occupants (who have no windows) ,
the velocity is always zero, even though they know a force is acting on them.

To Henri,

Androcles is grasping at straws. Of course I know that speed is measured in
miles per hour.

What I am saying is that time doesn't slow down when you travel at high
speed, since speed and time do not affect each other.
That is to say, a mile will remain a mile and an hour will remain an hour no
matter at what speed, as related to a stationary observer, you are
travelling.

When I heat a pot of water, its temperature will rise. We refer to this as
cause and effect.
There is no cause and effect between length traveled and the rate at which
time flows.

It APPEARS as if the twin is aging more slowly on his way out to the
stationary twin, because it takes progressively longer and longer for the
image of the moving twin to reach the stationary twin. But just because you
see it, that doesn't make it so, since in actual fact both twins keep aging
at the normal rate.

By the way the OBSERVED aging rate of the moving twin is LESS than normal on
his way out, and GREATER than normal on his way in. Since one cancels out
the other, both twins will have aged the same normal length of time. In
other words, speed does not affect the rate at which time flows, the two do
not interact.

Len.

That would be fine, H, but Len doesn't back them up when challenged.
Instead he finds some one-line quote from a book he's read that
he supposes will make his point for him, usually irrelevant. His entire
campaign to promote his "selected papers" (who selected them, Len?)
is founded on his wild imagination that someone, somewhere is going
to believe his helical photon theory, fundamental to which is light
speed being observer dependent. Len wants to agree with that and
is proposing a physical cause for same; he totally ignores any
evidence to the contrary. Having great ideas is one thing. Refusing
to listen to the ideas of others, especially when backed by evidence,
places Len in the same psychological category as the aetherialists and
the relativists. He doesn't snip, but he doesn't respond either.

That is simply the principle of relativity.
The rocket exhaust isn't feeling any force though, and it has a velocity
relative
to the ship that is dependent on time. You cannot even discuss velocity
without
time. Sure it can be constant, but it is meaningless without change of
position as
as function of time.

Not so, A.

The gradient of a hill is in metres/metre.
We sugar our cups of tea in 'gms/gm'.
Gold deposits are graded grms/tonne.

Similarly 'sec/sec' has meaning if there are two or more time sub-dimensions.

Shudder. Henri, in case you didn't notice, and I want you to concentrate
really hard now, there are THREE spatial dimensions. The gradient of a hill
uses TWO dimensions, nne vertical and the other horizontal. (Actually we use
the height and the hypotenuse, but that is simply convenience for a public
that has no knowledge of trigonometry.) We don't ever use metre per metre
in the horizontal plane, it is meaningless.



| We sugar our cups of tea in 'gms/gm'.

Really?
How many spoonfuls per spoonful do you use, H? One, perhaps?
I have 2 spoonsfuls in my coffee, but I only ever take one spoonful per
spoonful, one gram per gram, one ton per ton, one tonne per tonne.
How many tons are there in a ton, H?
Which is heavier, a ton of feathers or a ton of pig iron, H?
Or is it a ton of lead?
My granddaughter asked ME that, hoping to trip me up, H,
with a grin on her face.

| Gold deposits are graded grms/tonne.

How many grams in a tonne, H? Could it possibly be 1 million exactly?
How many microseconds are there in a second?


|
| Similarly 'sec/sec' has meaning if there are two or more time
sub-dimensions.

"If"? What do you mean, "if"? This is physics we are discussing, not
tick fairies. There are NOT two or more time dimensions, and secs/sec
always has the value ONE. IF you have two or more time dimensions
as there are two or more spatial dimensions, THEN you can have tick fairies.

So as I said, seconds per second is meaningless.

them.

That is simply the principle of relativity.
The rocket exhaust isn't feeling any force though, and it has a velocity
relative
to the ship that is dependent on time. You cannot even discuss velocity
without
time. Sure it can be constant, but it is meaningless without change of
position as
as function of time.
Androcles.


Sure, A.
That's why I said Len is not ENTIRELY wrong.

Shudder. Henri, in case you didn't notice, and I want you to concentrate
really hard now, there are THREE spatial dimensions. The gradient of a hill
uses TWO dimensions, nne vertical and the other horizontal. (Actually we use
the height and the hypotenuse, but that is simply convenience for a public
that has no knowledge of trigonometry.) We don't ever use metre per metre
in the horizontal plane, it is meaningless.


That's correct. There must be more than one spatial dimension for
'metres/metre' to be meaningful.

...but if you take a metre rule out into space, it doesn't wont tell you if it
is pointing along x, y or z.




| We sugar our cups of tea in 'gms/gm'.

Really?
How many spoonfuls per spoonful do you use, H? One, perhaps?
I have 2 spoonsfuls in my coffee, but I only ever take one spoonful per
spoonful, one gram per gram, one ton per ton, one tonne per tonne.
How many tons are there in a ton, H?


1 gm sugar to 100gms coffee, A.

The 'sugar' and 'coffee' effectively define two mass subdimensions.

That's why you can't add apples to oranges.


Which is heavier, a ton of feathers or a ton of pig iron, H?
Or is it a ton of lead?
My granddaughter asked ME that, hoping to trip me up, H,
with a grin on her face.

| Gold deposits are graded grms/tonne.

How many grams in a tonne, H? Could it possibly be 1 million exactly?
How many microseconds are there in a second?


A, you are giving Dinky lots of ammunition here.

| Similarly 'sec/sec' has meaning if there are two or more time
sub-dimensions.

"If"? What do you mean, "if"? This is physics we are discussing, not
tick fairies. There are NOT two or more time dimensions, and secs/sec
always has the value ONE. IF you have two or more time dimensions
as there are two or more spatial dimensions, THEN you can have tick fairies.

So as I said, seconds per second is meaningless.


Not so A.
I can set my watch to run at 0.9 secs/second(UTC)

Warning: Beware of the deranged one!
