(I'm liveblogging from TED 2008, in Monterey, CA)
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).
The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Thread count isn’t like one of those deceiving metrics like camera megapixels or Facebook friends—more threads are always better if you can afford them. If price was no object, we would all be snoozing soundly bundled up in 1.8 kilo-thread sheets every single night. Guess what? Price doesn’t have to be an object with this […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
