Falstad Math and Physics Simulations

Paul Falstad has created a comprehensive collection of educational interactive simulations covering oscillations, waves, electricity, magnetism, and quantum mechanics, originally written in Java but now converted to Javascript for broader accessibility. These applets allow students and educators to visualize complex physics and math concepts such as wave interference, electromagnetic fields, acoustic phenomena, and quantum mechanical orbitals through interactive demonstrations. The simulations span topics from basic wave motion and ripple tanks to advanced areas like quantum crystal behavior and antenna radiation patterns.
