Physics

Welcome to the physics page. Some special physical environments that will be used in this seection are listed and explained below.

Principles: a fundamental rule or concept in physics serving as a basis for reasoning.
Assumptions: a less fundamental rule or concept in physics that is taken to be true such that certain phenoma can be simplified.
Definitions: a precise and unambiguous description of the meaning of a physical term. It characterizes the meaning of a word by giving all the properties an only those properties that must be true.
Laws: a physical statement that is proved to be true, under the made assumptions and posed principles. In a physical text, the term law is often reserved for the most important results.
Propositions: an often interesting result, but generally less important than a law.
Lemmas: a minor result whose purpose is to help in proving a law. It is a stepping stone on the path to proving a law.
Corollaries: a result in which the proof relies heavily on a given law.
Proofs: a convincing argument that a certain physical statement is necessarily true. A proof generally uses deductive reasoning and logic but also contains some amount of ordinary language.

The physics sections of this wiki are based on various books and lectures. A comprehensive list of references can be found below.
