Presenter: Robert Lang, origami expert
Origami has been around for 100s of years. It didn't change until 1970s when it experienced a Cambrian explosion in variety and techniques. It got richer and more interesting because people started applying math.
The secret to origami, and so many other things, is to let dead people do your work for you, like looking at the geometry of disk packing.
Four simple laws can give rise to very rich complexity in origami. They have to do with properties of crease patterns, angles around a vertex, layer orders, and valleys and ridges. If you obey these laws you can make anything. He has a program on his website that will show you the fold patterns needed to make anything. (You give it a stick figure, it shows you the folds.)
He shows how he uses these mathematical ideas to fold a square sheet of paper into anything.
Origami has applications in other areas, like a solar array that flew in a Japanese satellite telescope, umbrella telescope, solar sail, airbag, heart stent (origami may save a life).
NASA today announced that astronomers studying data from NASA’s Great Observatories have found the best evidence yet for “cosmic seeds in the early universe that should grow into supermassive black holes.”
Could you recover a murder victim’s last sight of their killer by extracting it from the retina? Little more than a century ago, forensic scientists thought it might be possible. After all, in 1877 physiologist Wilhelm Friedrich Kühne was able to develop a simple image from an albino rabbit’s dissected eyeball. (Above, the two images […]
