Agnès Desolneux - Maximum Entropy Distributions for Image Synthesis under Statistical Constraints

The question of texture synthesis in image processing is a very challenging problem that can be stated as followed: given an exemplar image, sample a new image that has the same statistical features (empirical mean, empirical covariance, filter responses, neural network responses, etc.). E

Teach Astronomy - Universal Law of Gravity

http://www.teachastronomy.com/ Newton's master work is the universal law of gravity. Newton's law of gravity states that every object in the universe, every particle, every planet, every star, every galaxy, attracts each other with a force that is proportional to each of the masses of two

A quantum particle in a constant magnetic field

This is a first attempt at simulating a quantum particle in a magnetic field. The particle moves in a plane, and the magnetic field is constant, and perpendicular to the plane. The vector potential used in Schrödinger's equation is proportional to the vector (y, -x, 0). I hope to be able t

Maxwell’s Equations Part 3: Faraday’s Law

With the two forms of Gauss's law understood, we have covered the static aspect of electromagnetism. Now it's time to look at the more dynamic aspect by examining Faraday's law. This is a mathematical formalization of the notion that a changing magnetic flux will induce an electric current

Teach Astronomy - Symmetry

http://www.teachastronomy.com/ A lot of fundamental concepts in physics are based on the idea of symmetry. Symmetry is familiar to us in an aesthetic sense. It often means things that have pleasing proportion, or look the same from every direction, or have a harmonious nature about them.
