Скачать или смотреть The Jet Engine Was Built in the Stone Age

A modern jet engine shouldn’t exist.

Its turbine blades spin at 12,000 RPM, survive 1,600°C heat, and endure forces strong enough to tear steel apart. By every rule of physics, they should melt.

But they don’t—because their secret isn’t futuristic.

It’s 5,000 years old.

In this episode of Built Backwards, we reverse-engineer the most advanced metal on Earth and trace it back to a forgotten Bronze Age technique called lost-wax casting—used by ancient blacksmiths long before wheels, engines, or electricity existed.

You’ll see how:

A tiny bronze statue from 2500 BCE became the ancestor of jet engines

A dentist fixing teeth accidentally saved the U.S. Air Force

Ancient “disposable” clay molds power modern aviation

The same physics used by Bronze Age artisans still flies planes today

This isn’t a story about technology replacing the past.
It’s about the past quietly carrying the future.
