The ab initio way

[twynter94]

Why do we call quantum physics an ab initio model?
This is so because all the properties of quantum systems can be derived through solutions of the Schrodinger equation. Schrodinger’s equation is the fundamental equation of Quantum Mechanics, it cannot be further broken down into any other theories.

Why do we call classical mechanics an ab initio model?
Classical mechanics is referred to as an ab initio model because all the properties of the systems being studied can be derived through solutions of Newton’s laws which cannot be further subdivided into any other theories.

Is classical electromagnetism an ab initio model? If it is one, what are its first principles?
Yes, classical electromagnetism is an ab initio model and its first principles are Maxwell’s equations.
