However, the modern importance of gauge symmetries appeared first in the relativistic quantum mechanics of electronsquantum electrodynamics, elaborated on below.
15.
In relativistic quantum mechanics, relativistic wave equations predict a remarkable symmetry of nature : that every particle has a corresponding antiparticle.
16.
The development of non-relativistic quantum mechanics in the early twentieth century preserved the Newtonian concept of time in the Schr�dinger equation.
17.
In relativistic quantum mechanics and quantum field theory, it is not always possible to find a current, particularly when interactions are involved.
18.
It is an example of a hidden variable theory, and all non-relativistic quantum mechanics can be accounted for in this theory.
19.
This last relation is useful relativistic mechanics, essential in relativistic quantum mechanics and relativistic quantum field theory, all with applications to particle physics.
20.
The ability of non-relativistic quantum mechanics and special relativity to successfully describe observations motivated efforts to extend quantum concepts to the relativistic domain.
