Dynamics : An overview of the cause of mechanics
Dynamics is a subset of mechanics, which is the study of motion. Whereas kinetics studies that motion itself, dynamics is concerned about the CAUSES of motion. In particular, it involves the concepts of force, momentum and energy. This video gives an overview of what dynamics is, and is u

Interacting particles with spins
This simulation is a first step towards systems of interacting particles that have a rotational degree of freedom. Here each particle carries an angle, or "spin", indicated by a little dash. The particles interact with a Lennard-Jones potential, which determines the evolution of their posi

Thermodynamics 5a - Statistical Mechanics I
Previously we've seen that our "colliding billiard balls" model for a monatomic gas has chaotic dynamics. Therefore, it is hopeless to try and describe the exact dynamical evolution of such a system. However, we can turn this to our advantage by treating the system as so unpredictable that

A quantum Sinai billiard, phase evolution
Simulation of Schrödinger's equation for a quantum particle in a Sinai billiard. Luminosity corresponds to the probability of finding the quantum particle (modulus of the wave function squared), and the color's hue represents the phase (argument) of the wave function. The initial state is

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

AWESOME Brownian motion (with explanation)!
Brownian motion is the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. This pattern of motion typically alternates random fluctuations in a particle's position inside a fluid subdomain with a relocation to anoth
