Today I realize why two IT business of the semi-conductor and mobile communication devices have been emerged in our recent history compared to other business. After the Einstein's discovery of the new theory, two different device area technologies has been developed so greatly compared to other device technologies.
There were two important problems in modern science which are atoms and light. The behavioral rules of two areas are clearly proven by modern scientists. However, the relationship between two areas are not yet proven clearly. Once we focus on the atom force, we can not justify the force rule of the propagation. There is also another area of sound propagation which is in between of two other areas.
Material Force Rule
We call the rule of this as also Newtonian Rule.
Propagation Force Rule
Light and Electro-magnetics
We call this rule as Maxwell equation.
