Why Didn't Einstein FULLY Address Simultaneity-at-a-Distance?]]>

So, what is time?

Could it be an illusion?

Baby -> Kid -> Teenager -> Middle age -> Oldman

This is process changes, but not time itself.]]>

it is over 170 miles long, (274 kms), it produces high tide level that are tenX to fifteenX over the difference in tidal waters where I live.

So... could high tide levels near TRuro, N. S. to Moncton, N. B. be up by a meter or more if average ocean levels were to rise by ten centimeters?]]>

Janus' method for non-linear velocity addition]]>

I have determined that two adjoined points must be the smallest vector/scalar and the only way I can think of expressing this measure seems quantum spookiness .

0+0=1x

Is there any other way to express this ?]]>

On Vector Subspaces]]>

\[c^2=c^2\left(\frac {dt}{d \tau}\right)^2-\left(\frac {dx}{d \tau}\right)^2-\left(\frac {dy}{d \tau}\right)^2-\left(\frac {dz}{d \tau}\right)^2\] (1)

Differentiating both sides with respect to time we obtain

\[c^2\frac{d^2 t}{dt^2}\frac{dt}{d\tau}-\frac{d^2 x}{dt^2}\frac{dx}{d\tau}-\frac{d^2 y}{dt^2}\frac{dy}{d\tau}-\frac{d^2 z}{dt^2}\frac{dz}{d\tau}=0\] (2)

We transform to an inertial...

Accelerations in Special Relativity]]>

So if time is a continuous 'space' which looks like a continuous symmetry of nature, what does that mean? Time is always mathematically represented as an element of the real numbers, i.e. having just one dimension.

Simultaneous events have the same real number assigned to them, in a larger space (mathematically speaking).]]>

So there's no inner product, but apparently in an affine space, parallel lines still have the same 'structure' as in Euclidean space. So parallelograms are defined and there are volume-preserving functions. Distance isn't defined, but affine distance is (how, though?).

In abstract algebra a field is defined as a set equipped with a pair of closed binary operations, usually called \(+\) and \(\times\), for each of which there is an inverse, respectively \(-x\) and \(\frac{1}{x}\) and an identity,...

I wonder if someone who is good at LaTex could write a short tutorial of the basics, with some common SciForums examples? I'll write one up myself, but I'm a complete beginner at LaTex so it will take a little while.

Displaying equations using Tex]]>

In Yang-Mills theories there's a phase-shift 'operator' defined on particles from the Standard Model, that for instance, transform protons into neutrons and back.

But apart from that, we have fiber bundles, where a fiber can be a symmetry group, like SU(2). In an article by Bernstein and Phillips, the idea of a bundle of directions is used, such that each fibre is the interval [0,2π), but this only (obviously) makes sense if there is a...
