Falstad Math and Physics Simulations
A collection of educational applets designed to visualize complex concepts in physics, mathematics, and engineering. The simulations cover topics ranging from wave motion and electromagnetism to quantum mechanics and thermodynamics.
Why it matters
These tools provide accessible, interactive visualizations that help students and enthusiasts grasp abstract scientific principles.
These are some educational applets I wrote to help visualize various concepts in math, physics, and engineering. They were originally written in Java, but they've mostly been converted to Javascript, so you should be able to view them without a Java-capable browser.
