Classical Physics
Classical theory has at least two very important distinct meanings in Physics:
In the perspective of huge aspects, "classical theory" represents concepts of science that do not use the quantization paradigm, particularly Newtonian aspects (which are also known as traditional mechanics). Common relativity and unique relativity are also regarded to be "classical" in this sense
Classical theory represents traditional aspects
In the perspective of common and unique relativity, "classical theory" represents traditional aspects, and other concepts which respect Galilean relativity. Gentle and other electro-magnetic phenomena cannot be properly patterned in such a concept. Typically, light was reconciled with traditional aspects by supposing the everyday living of a "stationary" method through which light spread the aluminiferous anther.
Classical theory unique relativity
The everyday living of these two unique descriptions of the phrase can cause to confusion: unique relativity is a "classical theory" in the first feeling, but its estimations are more precise than "classical theory" in the second feeling.
In other situations, "classical theory" will have other meanings-if a present recognized concept is regarded to be "modern", and its release showed a significant paradigm switch, and then past concept (or new concepts using the mature paradigm) will often be called "classical".
