The Doppler Effect
Motion crowds the waves in front of a source and stretches the ones behind. That single geometric fact explains sirens, sonic booms, weather radar, and the expanding universe.
Maxwell's Equations and the Nature of Light
Maxwell combined everything known about electricity and magnetism, found a self-sustaining wave hiding in the algebra, and computed its speed from two bench-top constants. The answer was the speed of light.
Earthquakes and Seismic Waves
How a fault stores strain for centuries and lets go in seconds, why P waves arrive before S waves, and how the shadow that shear waves cast on the far side of the planet revealed a liquid outer core.
Resonance and Standing Waves
Why timing beats strength in every oscillating system — from a playground swing to a radio tuner, an MRI scanner, and the strings of a violin.
The Fourier Transform
Decompose any wave into its frequency components — and see why this changes everything.
Wave-Particle Duality
Fire electrons one at a time through two slits. What you find will change how you think about reality.
