BTW, [ct, x] may not be a vector if ct has the same direction as x,
in which case you cannot skew it. If ct has the same direction as x then
ct is scalar multiple of x, otherwise it may already be squewed or
stewed.


ct is not in the same direction as x in spacetime.

Ok, it can then be used as a base vector.


The way I usually draw it, t is vertical, and x is horizontal. They
really are different things.

That's ok too, although base vectors need not be at right angles.
However, time is not a vector at all.



You see, Androcles, you can take any two quantities, and plot them
against each other. Oranges, and apples, if you like.

Yes, and you can transform apples into oranges, right? I'd like
to learn that magic so I can teach it at Hogwarts.physics to young
witches and wizards like you. I'm quite willing to learn new tricks,
you see.
What's the rate of apples to oranges in these plots?



You could even
multiply the orange scale by "apples/oranges" so that the units
matched up.

Oh, very good. Suppose we have a rate of 2 apples per orange,
but I have no oranges. Can I make four apples disappear and
get two oranges in their place to go with my lunch? Do I have to
chant any spells, wave a magic wand or say a magic word? I do
like your magic, it is nicely insane, yes?


However, there isn't any physics in "orange & apple"
space that says that physical bodies are limited to a certain number
of oranges per apple.

Awww... there isn't? Apples and oranges are not real physical
bodies?

See, the way I understand it, we have mass, length, time, charge
and temperature; length comes in three varieties, x, y, z, and it
quite easy to turn length into length with a matrix. You sorta pick
the horizontal ruler up and set it down vertically, and I can _describe_
that with a matrix. If it's rubber ruler I can even stretch or skew it,
but I can't make it into time for some reason.


I haven't found out how to turn mass into charge or temperature
into length, either. Can you do those too?


However, there do appear to be physical laws
that limit particles to a certain number of meters per second.

Do there? Well bless my old boots, I've never met one.
A physical law that limits speed, you say? Amazing.

However, often the Lorentz Transformations are presented in a form
that maintain t and x as time and distance respectively, and the
matrix itself has unit conversion factors within it. You might be
interested in working with Mathematica sometime. When doing
particularly confusing mathematics, it can actually store units with
the numbers so at the end of a complicated calcualtion, it can
actually help you check your work to see if the units came out right.
It also has no objection to multiplying and dividing apples and
oranges, even in vector operations.

Does this address your concern regarding vector space?

No, it doesn't. Time is not a vector, it has no additive inverse.
Nor are oranges.

http://mathworld.wolfram.com/VectorSpace.html

Axiom 4: Existence of additive inverse: For *ANY* X, there exists
a -X such that X + (-X) = 0

See, that works just fine for length, I can do all kinds of wonderful
and useful rotations and translations using matrices on vectors of
type length. Why, some people even write games for computer
screens and you can see it happening!

But in the real world I can always walk home again when I go to
the corner store, but for some reason I can't get back to yesterday,
not even a little bit.

Of course, I'm talking about real physics and sanity, not theoretical
physics and insanity. You might wake up to reality sometime, although
I'm beginning to have my doubts. You certainly are confused.
Do your parents know you are deranged?

Oh, I do have to add this, it's a requirement of the thread title to
remain on topic. You need not read it, although I advise you do.


Einstein's postulate: "light is always propagated in empty space with
a definite velocity c which is independent of the state of motion of
the emitting body" bears no resemblance whatsoever to Green's:
"Einstein's 2nd postulate of SR says that the speed of light is c in
every inertial frame."

Green makes no apology for misrepresenting Einstein, instead he
mumbles "I insist on using a modern form of the 2nd postulate."

Green cannot distinguish a postulate from a conclusion.

Green is guilty of lying and has lost all credibility by attempting to
excuse himself.
He is a cheat with zero integrity to be treated with contempt by all.
Even if what he says on other subjects were to be proven true he
cannot be trusted, one would always need to check the source for
verification or denial.

You are a slightly different case, you don't have "Ph.D. physics 1956"
in your name so I can cut you some slack and say you were mistaken,
not deliberately and maliciously lying as the troll Bonehead Green does.
