First principle of physics
Weblaw of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later … WebThe principle of superposition Dynamical variables and observables Representations The quantum conditions The equations of motion Elementary applications Perturbation theory Collision problems Systems containing several similar particles Theory of radiation Relativistic theory of the electron Quantum electrodynamics See also [ edit] Physics portal

The author emphasises the systemic character of Aristotle’s philosophy by examining questions on metaphysics, epistemology, philosophy … In physics, a calculation is said to be from first principles, or ab initio, if it starts directly at the level of established laws of physics and does not make assumptions such as empirical model and fitting parameters. For example, calculation of electronic structure using Schrödinger's equation within a set of approximations that do not include fitting the model to experimental data is an ab initio approach.

The first principle simply says that the laws of physics apply equally to everyone in all situations. The second principle is the more important one. It stipulates that the speed of light in a vacuum is constant.
