Magic Debugged

Your phone knows where you are. A torn QR code still scans. Money crosses the country in seconds. It looks like magic. Let's debug it.
Magic Debugged is an animated channel that opens up the technology hiding in everyday things and shows how it really works: the cables on the sea floor, the maths inside a password, the tiny machine in your phone that counts your steps.
Every idea is explained from zero, with real code where it helps and sources in every description.
