Science & how things work
How a microwave heats food
Not heat from the outside — a fast-flipping electric field that twists the water already in your food. With a slow-it-down field demo and a turntable heat-map you can cook.
Open the explainer → ElectronicsHow transistors work
The MOSFET that runs the world, built from the field up — doping, the insulated gate, and why "nothing physically moves." Hands-on valve and logic demos.
Open the explainer → PhysicsHow GPS finds you
Not a map problem — a timing problem. Four satellites, the speed of light, and a clock trick, with a trilateration demo and a clock-error slider you can break.
