A massive monument carved out of solid rock, a monster-sized super-dome that defies the laws of gravity. These awe inspiring feats of engineering defy explanation, yet they are not modern--they were actually built thousands of years ago. The Great Pyramid was the tallest structure on earth for over 4,000 years! But what techniques, materials and tools could ancient engineers have used to build it? Stonehenge is one of the most mysterious structures ever built, but could the secret to its construction ever be revealed? Abu Simbel is ancient Egypt's greatest monument which even eclipses today's Mount Rushmore. How did the ancient engineers make the seemingly impossible possible?

Is it possible the ancient world had geniuses greater than ours today? The greatest scientific discoveries involve huge leaps of imagination, but you have to leap from somewhere. We are on a quest to find the ancient Einsteins, and this journey takes us straight to the amazing library of Alexandria in Egypt. It wasn't just a library with books. It was a center of innovation and technology. It was the silicon valley of the ancient world. The ancient Greeks weren't so constrained by religion, so philosophers and inventors were free to think about how the world works. And it's because of this that what we now call science was born. So they weren't just inventing things. They were inventing the actual processes of science itself.
