danshawen, nobody is taking you very seriously here because you keep ranting about things that have little or nothing directly to with special relativity, let alone Minkowski's framework.
Einstein's theory of special relativity claims that the Lorentz transformation is a symmetry of the laws of physics. This is analogous to how coordinate rotations ("no preferred spatial orientation") and translations ("no preferred position") are known symmetries of physics. At it's core, that's really all there is to relativity. Your various comments concerning photon/electron interactions, the Higgs mechanism, etc., are generally irrelevant because relativity isn't itself directly concerned with them. It's the (unspecified) "laws of physics" that are responsible for modelling specific physical processes like these. Relativity just claims that these "laws of physics", whatever they may be, should be Lorentz symmetric.
To understand what Minkowski did, you need to think about what relativity means for physics as a practice undertaken by human researchers. If we take relativity seriously then we need to be able to prove that the various theories that we come up with are symmetric under Lorentz coordinate transformations, as relativity claims they should be. The practical problem with this is that there's a whole soup of physical quantities that we're interested in that we'd like to have theories about. Some of these (like, say, the electric charge of a particle) are invariants, but many quantities are reference-frame dependent (for instance, velocity, momentum, energy, frequency, just about any current or density, the electric and magnetic field components, and on and on), and when we come up with theories about how these quantities are related to each other we need to make sure that we're equating them a consistent way.
What Minkowski did was invent a four-dimensional vector/tensor notation for relativistic physics that makes it much simpler to keep track of this zoo. He introduced a way of classifying physical quantities according to how they depend on the choice of reference frame: basically, represent all physical quantities as either invariants or as the components of four-vectors and tensors, which all share a common transformation rule if you change from one reference frame to another. This makes it almost trivially easy to develop theories that are compatible with the relativity principle: basically, any theory defined in terms of four-vectors and tensors and following a few simple rules is automatically guaranteed to be symmetric under Lorentz transformations. For example, if you have an equation in a theory saying
For a simple example of this, quantum physics says that the energy and momentum of a quantum particle are related to its wavefunction's (angular) frequency and wavevector by the de Broglie relations:
To summarise, Minkowski introduced a mathematical book-keeping tool that makes it trivially easy and systematic to show that theories are consistent with special relativity. This might not be much of a concern to you personally, but it's something we need to do all the time in theoretical physics and it's why Minkowski's framework is as widely used as it is, and your bizarre rants about "19th century mathematics" and such show virtually no understanding or even awareness of this.

For example, if you have an equation in a theory saying
$$\text{a four vector} = \text{another four vector} \,,$$
then the components on both sides of the equation change in the same way if you change the reference frame, so the equation is preserved by the change of reference frame.For a simple example of this, quantum physics says that the energy and momentum of a quantum particle are related to its wavefunction's (angular) frequency and wavevector by the de Broglie relations:
$$\begin{eqnarray}
E &=& \hbar \, \omega \,, \\
\boldsymbol{p} &=& \hbar \, \boldsymbol{k} \,.
\end{eqnarray}$$
In Minkowski's notation, you can group energy and momentum together into a four-vector called the "four-momentum", defined by $$p^{\mu} = (E/c,\, p_{\mathrm{x}}, p_{\mathrm{y}}, p_{\mathrm{z}})$$, and, like I mentioned earlier in this thread, you can group the frequency and wavevector of a wave into the "four-wavevector" $$k^{\mu} = (\omega/c,\, k_{\mathrm{x}}, k_{\mathrm{y}}, k_{\mathrm{z}})$$. So, in Minkowski's notation, the de Broglie relations would just be expressed asE &=& \hbar \, \omega \,, \\
\boldsymbol{p} &=& \hbar \, \boldsymbol{k} \,.
\end{eqnarray}$$
$$p^{\mu} = \hbar \, k^{\mu} \,.$$
This is mathematically equivalent to the way the de Broglie relations are written above, but expressing them in this way makes it immediately obvious, to any physicist familiar with Minkowski's framework, that the de Broglie relations are compatible with the relativity principle.To summarise, Minkowski introduced a mathematical book-keeping tool that makes it trivially easy and systematic to show that theories are consistent with special relativity. This might not be much of a concern to you personally, but it's something we need to do all the time in theoretical physics and it's why Minkowski's framework is as widely used as it is, and your bizarre rants about "19th century mathematics" and such show virtually no understanding or even awareness of this.
