And so in the molecules that make you, you can detect and correct errors, and you don't need a ruler to make you.
The geometry comes from your parts.
So now compare a child playing with Lego and a state-of-the-art 3D printer or computerized milling machine.
the tower made by a child is more accurate than their motor control because the act of snapping the bricks together gives you a constraint on the joints.
You can join bricks made out of dissimilar materials.
You don't need a ruler for Lego because the geometry locally gives you the global parts and there's no Lego trash.
The parts have enough information to disassemble them.
Those are exactly the properties of a digital code.
The unreliable is made reliable.
Yes, absolutely.
So what the ribosome figured out 4 billion years ago is how to embody these digital properties, but not for communication or computation in effect, but for construction.
So a number of projects in my lab have been studying the idea of digital materials.
And think of a digital material just as Lego bricks.
The precise meaning is a discrete set of parts reversibly joined
with global geometry determined from local constraints.
And so it's digitizing the materials.
And so I'm coming back to what are the biggest things I've made.
My lab was working with the aerospace industry.
So Spirit Aero was Boeing's factory's
They asked us for how to join composites.
