Robert Full: Learning from the Geckos Tail

Filed under: TED2009 ::

I’m standing in for Ethan Zuckerman, blogging from TED today. This post is part of a series from the TED 2009 conference held in Long Beach, California from February 4-8th. You can read other posts in the series here, and the TED site will release video from the talk in the coming weeks or months.

Robert Full studies cockroach legs and gecko feet. His research is helping build the perfect “distributed foot” for tomorrow’s robots, based on evolution’s ancient engineering.

He has created “stickybot”, a robot that emulates a gecko using the same mechanisms that normal geckos use. It even has a tail. Why? Well, it turns out that the robot falls off the wall otherwise. It’s tail serves as a fifth leg.

For TED, they have created a special gecko robot with a tail that does automatic air-righting if it falls when hanging upside down. He’s showing some amazing video of this robot, but even more inpressive video of the real geckos being blown around wind tunnels and on glass surfaces for how htey learned this. There’s even a video of a gecko flying through the air, gliding. Using it’s tail to guide its path through the air.

Shai Agassi is a green auto pioneer, and he wants to put you behind the wheel of an electric car — but he doesn’t want you to sacrifice convenience (or cash) to do it. Check out his amazing project at Better Place, and make sure to read his blog.

How would you run a whole country without oil?

Shai focuses in on the electric car. You need a car that’s more convenient and more affordable than today’s cars. This isn’t a $40k sedan, nor is it something you drive for one hour and charge for 8 hours. So, how do you do this?

eMiles and electric cars

You separate the car and battery ownership. You create a network before you create the devices, a network for charging your vehicle. The second step is increasing the range extension (which currently is about 120 miles). You have a batter swap system, which actually happens less than what people normally stop for fuel in a normal car.

From molecules to electrons:
Gas tank >> Battery bay
Crude oil >> Battery pack

eMile, the new commodity. In 2010 this is about 8 cents/mile. But, in his model they follow Moore’s law, where by the year 2020 he expects it to be about 2 cents/mile.

“Hybrids are like mermaids. When you want a fish you get a woman, when you need a woman you get a fish.”

Where has this been working? Israel, Denmark, Australia, Hawaii and San Francisco.

Shai foresees 10 million electric vehicles by 2015. A future where all the cars will be driven by windmill power (in Denmark) and by solar power in other areas.

Elizabeth Gilbert: Genius and how we ruin it

The author of “Eat, Pray, Love“, Elizabeth Gilbert has thought long and hard about some large topics. Her next fascination: genius, and how we ruin it.

Elizabeth

Elizabeth weaves an insightful story of artists, success and pressure. She asks if she’s doomed. What if she never replicates the success of her past book? Is it rational or logical to be afraid of the work that we were put on this earth to do? Why have artists and writers had this history of manic depressive and mental illnesses? Why does artistry always lead to mental anguish?

“I think it might be better if we encouraged our great creative minds to live.”

“It’s exceedingly likely that my greatest success is behind me. That’s the kind of thought that can lead a person to start drinking gin at 9:00 in the morning.”

She states that she now needs to create some safe psychological construct. She’s looking at other societies and understanding how they have dealt with this same issue. That led her to ancient Greece and Rome. In their world, the brilliance and genius around ancient artists were attributed to daemons and spirits. It protected them from narcissism in success and suicidal failure.

The big change happened when we decided that the person, who is this artist, is the center of the universe. It’s too much pressure to ask one person to think of themselves as this single vessel of all artistic understanding of the world.

Louise Fresco: The Problem of Romantasizing Bread

Filed under: TED2009 ::

Louise Fresco is a powerful thinker and globe-trotting advisor on sustainability, Louise Fresco says it’s time to think of food as a topic of social and economic importance on par with oil — that responsible agriculture and food consumption are crucial to world stability.

Bread is a standard diet for people all over the world, not just in the West. She shows Wonder bread and the whole wheat bread and asks which one people like more. It’s overwhelmingly for the whole wheat, home made bread.

Bread

“We have this mythical image of how life was in the rural, aggricultural past.”

The industrial revolution brought us many great advances. But it also created a world of supermarkets. We shouldn’t despise the Wonder bread, because it means that we have created a way to make bread available to all. Even though it is tasteless and has a lot of problems, it has changed the world.

In the last few decades, since the 1960′s food availability has grown by 25%. This means we have more food available now than any other time in human history. As food became plentiful, it also meant that we were able to decrease the number of people who were working in agriculture (in the US, only 1% of the population works in agriculture.)

“Never before has the responsibility to feed the world been in the hands of so few people. And, never before have so many people been ignorant of that fact.”

Bread is now associated with obesity, because we’ve begun to add more and more high calorie ingredients to it. The price of mass production has been the destruction of many of our landscapes, and the costs have been tremendous with regard to the habitats.

How many of you can actually tell wheat apart from other cereals? Do you know how much a loaf of bread actually costs?

The counter movement is to go back to small scale, farmers markets and home made bread (much of that started in California). This is a fallacy, of us romanticizing the past. This is a luxury solution for us. We will be relegating the other agriculturalists around the world to poverty. It puts local food production out of business, and puts the urban poor out of food.

We need more science, and good science, to better understand the technology around pest and disease resistance. We need to think about urban food systems and to combine agriculture and energy. Most importantly, we need a food policy, not just an agricultural policy.

Nina Jablonski is author of Skin: A Natural History, a close look at human skin’s many remarkable traits: its colors, its sweatiness, the fact that we decorate it.

She dives into the life of Darwin. Specifically, she is talking about human skin pigmentation. Darwin rejected the idea that skin color was determined by the sun, the environment. Nina states: “if only he lived today, If only Darwin had NASA.”

What Darwin didn’t appreciate, was that there was a fundamental relationship between ultraviolet radiation from the sun and people’s skin color. She shows a map of the predicted skin color derived from multiple regression analysis.

Map of skin color

Darkly pigmented skin is highly protective under intense UVR areas, melanin is a natural sunscreen. She states that as people moved around the world, from high UV to low UV areas, there were skin color repercussions.

On how the globalization of travel (example: a white African’s like me, living in Sudan as a kid) : “We are living in environments where our skin pigmentation is not properly adapted.” There are both health and social consequences.

Golan Levin on Art that Looks Back

Golan Levin is an artist and software engineer who is here to talk to us about experiments in interactive art. He asks, “Where is the “art” category in the iPhone app store?” Golan is interested in discovering how to empower people through interactive art.

golan_switz_2002

Currently, he’s walking us through how certain sounds have a higher probability of creating certain shapes. Then, how the tool he created takes people’s voices and throws letters and shapes onto a canvas in real time. This has repercussions for voice recognition software.

This is called Ursonography, and below is an example of it:


Ursonography (Excerpts), Jaap Blonk & Golan Levin, 2007 from Golan Levin on Vimeo.

Now he’s really doing some crazy things with eye-tracking software and the way that it can be used to create art that knows it’s being looked at and creates itself. He calls this Eyecode.

Ed Ulbrich: Creating a Digital Person in 18 Minutes

At Digital Domain, Ed Ulbrich works at the leading edge of computer-generated visuals. On a recent project, filmmakers, artists, and technologists have been working at a breakthrough point where reality and digitally created worlds collide. His most recent work can be found in the Curious Case of Benjamin Button film, starring Brad Pitt.

Benjamin Button

They first started on this project back in the ’90s and had to throw in the towel because the technology just wasn’t up to creating these visual effects. The “holy grail” of the industry is digitizing the face. The problem was, there is no margin for error when doing this with a face as well known as Brad Pitt.

Ed tells of how nervous he was when the finally realized they could do it, and then got the “go ahead” from the studio. It was a daunting task. They had to take all the details and idiosyncrasies that make up Brad Pitt in order to make it real (for a full hour of the movie).

Step 1: admit you have a problem
Step 2: break the problem down

The current technology (in 2004) wasn’t really up to the task, so they had to walk away from all that was in this movie and video game space. Instead, they had to make their own technology “stew” that would be able to handle what they were trying to do.

FACS – Facial Action Coding System and Contour by Mova allowed them to do so much more. They ended up stipling Brad Pitts face and getting every 3d possibility of what his face was capable of doing.

The problem… Brad was 44 and Ben needed to be 87 years old. Ed just unveiled to us a 100% representation sculpture of Benjamin Button in three different age increments. (Absolutely incredibly… looks so real). Then they transposed that 3d data onto the sculpture. In the end, they created a real life puppet that Pitt could control with his face.

Olafur Eliasson: Art and our Sense of Space

Today’s session is titled “See”, and that’s just what we’re doing with Olafur Eliasson and his artwork. He is also behind 121 Ethiopia, an African nonprofit.

Olafur Eliasson: The Weather Project

Olafur thinks of his studio in Berlin as more of a lab, where they do a lot of experimentation. He is asking us to stare at a screen, which has colors in certain shapes. When the image disappears, we see the complimentary color in the same shape. Though the narrative isn’t that exciting, he claims we are co-producing a movie.

My view from the blogging area

Olafur tries to make art that helps people feel a part of a certain space. As an example, he tells of his large waterfall artwork that gives a sense of size to people in New York City. Where you can finally get a real feel for what the size of the space you’re in is.

Oliver Sacks: Seeing with the Mind

Oliver Sacks

We start this morning with Oliver Sacks, who since Awakenings first stormed the bestseller lists (and the silver screen), has become an unlikely household name, and single-handedly invented the genre of neurological anthropology.

We see with our eyes, but we also see with our minds. Hallucinations is what he will be talking to us about today.

Oliver tells a story of an old lady who was “seeing things”. Who ended up being a perfectly sane and lucid lady, who had been very startled because she had been, “seeing things”. She had been completely blind, through macular degeneration for 5 years, but now was starting to see people in Eastern dress, cats, dogs, and a man with large teeth on one side of his face. Sometimes, she might hallucinate black and pink squares on the floor that go up to the ceiling. In her words, “It’s like a movie, a very boring movie.”

She was confused, and thought she might be going mad. She wasn’t, she had Charles Bonnet Syndrome: an anarchic visualization stimulation release.

10% of visually impaired people get visual hallucinations.
10% of hearing impaired people get hearing hallucinations.

As the visual parts of the brain aren’t getting as much input, they start to become hyperactive. Oliver tells us amazing stories of people what people see. Of boys flying up to 100 feet, men splitting into 6 parts and cartoons come to life.

Functional Brain Imagery (FMRI), has been possible in the last couple years. He tells us how the different parts of the brain are being activated and which are overactive for certain types of hallucinations, and it’s different parts that see teeth and eyes, from buildings, landscapes or cartoons.

He reminds us that blind people all over the world, many times have cases of hallucinations, yet they probably don’t share those with people for fear of being seen as crazy.

Pinch-hitting

Filed under: TED2009 ::

As much pride as I like to take in thoroughly liveblogging TED, there’s going to be a hole in my performance, as I will be in Denver tomorrow accepting an award on behalf of Global Voices. But I’ve arranged an astounding pinch-hitter. The inimitable Erik Hersman, of White African, Afrigadget and Ushahidi fame, is going to be sitting in, cross-posting some of his blog notes here. I’ve literally never had a guest blogger on this blog previously, but I can think of no better man to take the reins – you’ll be in good hands. Enjoy Erik’s coverage and see you Friday.
