Huygens Principle

This undergraduate textbook presents thorough coverage of the standard topics of classical optics and optical instrument design; it also offers significant details regarding the concepts of modern optics. Its survey of the mathematical tools of optics grants students insights into the physical principles of quantum mechanics. Two principal concepts occur throughout: a treatment of scattering from real scatterers (leading to Huygens' principles, diffraction theory, the index of refraction, and related topics); and the difference between coherent and noncoherent wave phenomena. Two sets of problems appear at the end of each chapter, some featuring detailed solutions. 1969 ed. 252 figures.

Huygens' principle - Huygens' principle (named for Dutch physicist Christiaan Huygens) is a method of analysis applied to problems of wave propagation in the far field limit. It recognizes that each point of an advancing wave front is in fact the center of a fresh disturbance and the source of a new train of waves; and that the advancing wave as a whole may be regarded as the sum of all the secondary waves arising from points in the medium already traversed.

Wavicles - Wavicles are the point sources used in Huygens' principle, which states that all points on a wave front can be considered as point sources, e.g.

Non-aggression principle - The non-aggression principle (also called the non-aggression axiom, anticoercion principle, or zero aggression principle) is an ethical prohibition against "aggression," which is defined as the initiation of physical force or the threat of such upon persons or their property (the principle does not preclude retaliation against aggression). It is an essential tenet of all libertarian thought, though some libertarians view it as more of a guideline than an ironclad rule.

Church–Turing–Deutsch principle - Alonzo Church, Alan Turing, and David Deutsch contributed to the Church–Turing–Deutsch principle, also known as the CTD principle, of computer science. The principle states: A universal computing device can simulate every physical process.
