So what is Special Relativity; what does it do?

Relativity by Escher

What is special relativity?Every system of coordinates can map the whole of Spacetime but how do we take the measurements, the coordinates from one system and convert them to be relative to another system of coordinates?To put it another way; how do we make the measurements and coordinates of a spatial framework, a system, relative to a passing observer?

By adding the vector (magnitude and direction) of their relative velocity to each and every measurement or coordinate.

This works fine until we approach the speed of light which Einstein added as a limiting postulate in his Special Relativity.

Using the Lorentz Factor to adjust or transform those measurements resolved the difficulty, but how?

By rotating the system of coordinates into another dimension.

Yes, another dimension.

Sounds extreme maybe, but consider:
in one dimension we rotate into a second dimension to form a triangle;
in two dimensions we rotate into a third dimension to form a cone;
in three dimensions we rotate into a fourth dimension to form what? A four dimensional figure that we cannot picture!

But in each case the rotation accounts for the addition of a vector in another dimension and so doing it exactly fulfils the formulation of the Lorentz Transformation Equations.

So we add the relative velocity using the Lorentz Transformations and it resolves the problem of the limiting speed of light.

We can take any 3 dimensional set of coordinates – or 4 dimensional when we include Time as a temporal dimension – and, by adding the relative velocity of a moving observer by means of the Lorentz Transformation Equations, by means of an extra dimension, we can recalculate that system relative to the moving observer.

This does not effect the Newtonian Rotation that determines directions but adds the additional, Minkowski Rotation, to that set of coordinates and thereby we remain within the confines of the speed of light

About TyroJack

For me the World is a logical place, in a Universe that works according to strict, straightforward and uncomplicated Laws. Physical Laws. Many of which we are aware of some of which we understand, some that we have working theories about, some we hypothesise about and some that are as yet pure guesswork. I believe in William of Ockham's principle, known as Occam's Razor: 'The fewer assumptions one makes, the more likely one is to be correct.' I like to apply this in life as well as science. I worked in various roles in IT for most of my working life which could be summed up as programming consultancy. Primarily I fixed problems from the most basic coding, to System design. I programmed systems that were bug-free. I am interested in everything and anything, but most of all in how things work.
