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 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.
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.
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.
Decompose any wave into its frequency components — and see why this changes everything.
Fire electrons one at a time through two slits. What you find will change how you think about reality.
