THE MATHEMATICAL THEORY OF HUYGEN'S PRINCIPLE. B.B. Baker, E.T. Copson.
Publisher: Oxford University Press: 1950 2nd ed.

Finally, $\kappa$ is a “reality factor” to unite theory and observation, which we need to discuss a bit more in detail. A word of warning: While most of the following is extracted from books and other public sources, I make . Luckily, diffraction is really very straightforward once one grasps said Huygens-Fresnel principle; the rest is just mathematical sleights of hand as we'll see. She wrote a wonderful book with the title of this article/blarticle, which my 14-yr-old son gave me for Christmas, along with 50 Mathematical Ideas You Really Need To Know. Fresnel (Go through the idea of Fresnel integrals, and try to imagine how a young on-site engineer might have built this theory after coming back tired from the field work in the day, living in tents, with only a handful of mathematics books gathered at radom serving as references, writing with the quilt pen, and of course without electric light.). Wigner, who worked on group theory and symmetries in physics, wrote a famous article on the “Unreasonable Effectiveness of Mathematics in the Physical Sciences”, Communications in Pure and Applied Mathematics, vol. Both are wonderful introductions to Hooke's law 8. Entropy, Huygens' Principle; the wave/particle, energy/mass, space/time, and E/B dualities; and time and all its arrows and asymmetries emerge from a common, foundational physical model. Phases: It was Fresnel who independently rediscovered the Huygens principle on his own, and introduced phases in the theory. Figure 3: Geometry of the diffraction problem, as described by (3).
