TL;DR: Derek Muller unpacks how jet engines survive 2,000°F+ temperatures without turning into molten goo. He starts with the basics—engine airflow, compressor, combustion chamber and turbine—then zooms in on the real MVPs: nickel-based superalloys, precision casting at Rolls-Royce, and single-crystal blades whose internal crystal structure and clever cooling channels keep them below melting point.
Along the way you’ll get a whirlwind tour of engine history (hello, the first jet engine!), edge dislocations in metals, the Gamma-prime phase that hardens nickel alloys, and why sand in your engine is a very bad idea. It’s a geeky joyride packed with slick animations, expert interviews, and just enough materials science to make turbine blades—and your brain—stay remarkably cool.
