It could be seen from the previous success of electrodynamics that the relativistic theory of gravitation would have to use the concept of a field or something similar.
22.
In other words, one needs to design the Minkowski space-time formulation of a relativistic theory that is not based on any a priori perturbative scheme.
23.
Thus, classical mechanics predicts that there should be no Doppler effect for light waves, whereas the relativistic theory gives the correct answer, as confirmed by experiment.
24.
The desired definition of a relativistic theory involves calculations of as many observables as one must use in order to fix all the parameters that appear in the theory.
25.
This structure provides the background setting of all present relativistic theories, barring general relativity for which flat Minkowski spacetime still provides a springboard as curved spacetime is locally Lorentzian.
26.
For a relativistic theory the propagator should be defined as the sum over all paths which travel between two points in a fixed proper time, as measured along the path.
27.
He was the first in 1928, to calculate the fine structure of the hydrogen atom under P . A . M . Dirac's relativistic theory of the electron.
28.
One of the conditions that a relativistic theory of gravitation must meet is to be mediated with a speed that does not exceed c, the speed of light in a vacuum.
29.
In a non-relativistic theory, this product can be interpreted as annihilating two particles at positions x and-x with polarizations that are rotated by \ pi relative to each other.
30.
Relativistic effects in chemistry can be considered to be perturbations, or small corrections, to the non-relativistic theory of chemistry, which is developed from the solutions of the Schr�dinger equation.
