But what I was amazed about is this reverse engineering and know how that's built into this little two meters of space.

We want to have some people, who really know how to do this, perform human engineering studies to develop the optimum design for the portable device for treating migraine headaches.

We live in a world of diverse cultures, and we know very little about social engineering and how to build nations. When we cannot be sure how to improve the world, prudence becomes an important virtue, and grandiose visions can pose grave dangers.

But, then was the really interesting aspect of the work, following the engineering part, where, basically, we're coding over Dan's shoulder at the hospital extensively to figure out, you know, how does Dan move?

They know how to plant organic rice, they know how to look after it, they know how to harvest and they know how to cook it.

But how will we know? How will we come to know?

You know how to immunize kids, you know how to give bed nets.

How to know?

Natalie Jeremijenko's unusual lab puts art to work, and addresses environmental woes by combining engineering know how with public art and a team of volunteers. These real life experiments include Walking tadpoles, texting fish, planting fire hydrant gardens and more.

But it tells us that we know how to create it, we know how to create it cost effectively, we know how to handle it safely.

And then, more recently, they really began to do sort of reverse engineering on this beast and figure out just what the parts were, how they worked and how they might be optimized how they might be made better.
