Are you saying that Albert Einstein got his relativity Time and Fourth Dimension idea from reading a ...science fiction book????

As everybody knows Einstein was extremely put off by the use of 4D chrono-geometry for relativity and had to be dragged kicking and screaming into accepting the notion. It was Minkowski (his math professor) who started using it -- in a paper published in 1908 -- not Einstein (who in fact co-published a series of papers with Laub on the very same topic as Minkowski's paper (the relativistic version of the equations for constitutive media in electromagnetic theory)).

As far as where the idea stems from -- like it or not -- that's Galileo (even despite himself). For the following reason:

Euclidean 3D geometry is founded on 3 degrees of translational symmetry and 3 degrees of reorientation symmetry. Likewise a single time dimension possesses it 1 degree of (translation) symmetry. But the instant you pose any symmetry law that involves both space and time you have a unified chrono-geometry and it was Galileo who first posed the 3 degrees of "boost" symmetry (hence the name "Galilean transformation") by virtue of saying that motion was relative. That forces the geometry to be 4 dimensional.

In fact, the reason Newton was so dead set against the idea of motion being relative is exactly that: it makes any formulation based on 3D geometry impossible since the geometry's most fundamental undefined (the "point") ceases to have any meaning if motion is relative. (i.e. what counts as the "same point" at two different times if you don't know when you're moving or not).

So for that reason Newton's law of inertia was stated in two parts: one for the stationary case and the other for the moving case, while never acknowledging anywhere in his treatment that the two cases were at all equivalent.

Sorry, I'm not aware of any "observation and experiment" of  Three
spacial and one temporal
dimension fit *any* observations or experiments.


Are you gettin your info from...a science fiction story? I didn't read
the book The Time Machine. I saw it on teevee..

Minkowski did quite a bit of interesting, n-d stuff,
but this was just a fuck-up, then he died at 43.

it is simply a phase-space, and there is never
any need to spatialize time, if you have a flipbook.

It's true "Starmaker". A rotating umbrella can make you travel time!

Go read the book "flatland" and then come back here and discuss dimensions.

It's about only three dimensions, not a fourth and Time.

I asked the question: Who invented this thing called the fourth dimension and that Time is in it?


The reason why I asked is because timeline wise, the earliest mentioned was H.G. Wells in his
science fiction book The Time Machine, 1895. The, next in the timeline is Albert Einstein relativity ten lears later 1905.



Now, I'm wondering timeline wise, who was before H.G. Wells? Or, is it a fact this whole 
"4 dimensions and time" the foundation is just ...science fiction.


In other words, 4 dimensions and time is not Science, it's science fiction.


Unelss of course you can come up with '4 dimensions and time' before H.G. Wells. 

Who invented 4 dimensions and time?


I'll repeat the original question: "Who invented this thing called the fourth dimension and that time is in it?" 


Was it H.G Wells, or was it somebody before him?

what exactly do you mean by "fourth dimension and that Time is in it"

I agree, it's science fiction that neither SR nor GR uses.
SR/GR uses 4 dimensions, when the fourth dimension is time,
recalculated to path length of the light in vacuum.

if Minkowski had used a flipbook,
he could have had two spatial & one time; since,
apparently, he did not do that,
we have been stuck with a horrible nonsequiter
of spatialixing time.

mainly, though, it is because of newton's fuck-up
with the rockton or photon,
a word taht was entirely servicable before & ever after
to denote a quantum of wave-action through the atoms of free space

   I so sorry, I should have pointed out that GPS receivers measure and
   spit out values for three spacial and one temporal dimension.

One popular SR book ( Spacetime physics I guess )

comes with the analogy
there was once upon the time a weird city,
where East West distances were measured in metres,
while North south ones in the sacred units.

And that there were 2 groups of surveyors that hated each other.
the day one using compass, the night one using stars.

And that was problem, as "day north" was not "night north"

The data and maps of both groups were not compatible,
as N-S and E-W distances they measured did not fit each other
and maps of the city were rotated.

It was a big problem, until came one surveyor,
that secretly studied in both surveyor schools.

And this guy came with deadly heretic idea
to recalculate the value in sacred units into meters.

Using unified calculations he found interesting invariants ,
values being the same in both systems, and transformations,
comparing data from both groups.

It is funny, until one realizes,
this weird city is Earth
the sacred unit is second.
Not fitting distances are length contraction and time dilation
Not fitting maps are reality in different inertial frames
and the transformation is the Lorentz one.
