Advanced but still Primitive

This story about evolutionary hardware design was indeed, as the URL indicates, a damn interesting read. The thing that struck me the most was that the design the evolutionary algorithm came up with didn’t work on other chips of the same type, just on the chip on which it evolved. The minute differences between different chips of the same type are negligible if their use is limited to things we currently understand, but if the only constraint is the laws of physics then the solutions that evolve are so complex and out of the ordinary that, were we to understand them, our advanced tools would probably seem like sticks and rocks.

Materials: The Most Important Engineering?

I’m watching “Ancient Discoveries: Machines of the East” on Discovery and as usual, there’s some amazing things those ancient inventors came up with. I just saw a device that pours a fixed amount of water at a fixed interval. It used a siphon and a float based valve like that in a modern toilet. The show said this showed an advanced knowledge of differential pressures, which is used today to make jet engines. Was the only thing stopping them from making jets a lack of the materials that could withstand those forces?

There’s seems to be a first key invention that starts a field of science/engineering, like the discovery of the wheel to mechanics, electricity to electronics, etc. But beyond that, could it all be a matter of making the “things” of your discipline out of lighter, stronger, or other interesting materials?

This idea is just off the cuff, I’d like to hear some comments either way.
