Interactive visualizations for engineering and science education
Proportional control of an underwater robot. Adjust gain, mass, and drag to explore overshoot, damping, and rise time. Based on HMC E79.
Two masses orbiting their common center of mass. Adjust masses, semi-major axis, and eccentricity to explore Kepler's laws and orbital mechanics.
Identify issues in scientific figures using the HMC E80 rubric. Click on problem areas, classify issues, then check your answers against the key.
Compare pixel-by-pixel vs. DCT frequency ordering to see why JPEG compression works. Same data, different basis — dramatically different quality.
