A Visual History of Human Knowledge | Manuel Lima | TED Talks



How does knowledge grow? 
Source: EPFL Blue Brain Project. Blue Brain Circuit
Sometimes it begins with one insight and grows into many branches. Infographics expert Manuel Lima explores the thousand-year history of mapping data — from languages to dynasties — using trees of information. It's a fascinating history of visualizations, and a look into humanity's urge to map what we know.

An Extraordinary Glimpse into the First 21 Days of a Bee’s Life in 60 Seconds



In an attempt to better understand exactly what happens as a bee grows from an egg into an adult insect, photographer Anand Varma teamed up with the bee lab at UC Davis to film the first three weeks of a bee’s life in unprecedented detail, all condensed into a 60-second clip. The video above presented by National Geographic doesn’t include commentary, but Varma explains everything in a TED talk included below.

The primary goal in photographing the bees was to learn how they interact with an invasive parasitic mite that has quickly become the greatest threat to bee colonies. Scientists have learned to breed mite-resistant bees which they are now trying to introduce into the wild. Learn more about it in this video:

Ella tiene la solución para salvar a las abejas. Es tan sencilla que no podrás creerlo


Las abejas están en problemas, pero hay algo que todos podemos hacer para ayudarlas y empieza en nuestro hogar. 

Hoy las abejas se enfrentan a un difícil momento, sus poblaciones están en peligro y han disminuido drásticamente en el último tiempo. Ellas son las responsables de que exista gran parte de los alimentos que consumimoscerca de 1/3 de los cultivos– entre los que se encuentran las manzanas, brócoli, cerezas, arándanos, peras, fresas, melones, limones y muchos otros. La alfalfa también requiere de la polinización de las abejas para existir, y si están pensando en que no es muy importante para nuestra dieta, sí es el principal alimento para muchos animales. Así que si las abejas están en problemas, nosotros estamos en problemas. 

Por suerte sabemos que hay un modo de ayudarlas a salir de esta crisis pero cuando esta mujer te explique que lo que las puede salvar es algo tan sencillo como plantar flores, quizás te cueste trabajo comprenderlo.

Hay varios factores que han llevado a la población de abejas a esta crisis del Colapso de las Colmenas.


  • Para empezar está el hecho de que hemos hecho desaparecer a sus flores favoritas. Para las abejas, interminables campos sin flores son en realidad como un desierto donde no pueden encontrar alimento. 
  • Los pesticidas que se utilizan en la agricultura también son una gran amenaza –además del detalle que significa que campos silvestres desaparezcan para convertirse en tierras de cultivos–. 
  • Estos puntos combinados con enfermedades naturales que estos insectos sufren, han hecho que las poblaciones de abejas se reduzcan rápidamente.

Así que ya lo sabes, plantar flores podría ser una gran ayuda para estas pequeñas trabajadoras. Si son nativas ¡mejor!. Incluso podrías tener otros visitantes como mariposas y colibríes en tu jardín o el balcón de tu apartamento. Y realmente…es así de fácil.

"La creatividad se aprende igual que se aprende a leer"

ORIGINAL La Vanguardia
03/11/2010 - 03:09
Foto: Marc Arias Tengo 60 años: irrelevantes cuando eres capaz de crear como un niño, y todos somos capaces si queremos. Nací en un barrio humilde de Liverpool, como los Beatles, creativos sin escuela. No soy buen gregario, así que no tengo partido, pero sí política. Colaboro con el Foro HSM


Buscando la 'zona'
Salgo tan inspirado de la entrevista a Ken Robinson que no me resigno a reducirla a esta Contra. Así que, si ustedes me lo piden, explicaremos de su mano en breve cómo encontrar nuestro elemento creativo. Porque a ser innovador se aprende igual que a sumar: a cualquier edad y en cualquier circunstancia, con la única condición de tener ganas. Robinson precisa cómo lograrlo en el informe que está transformando la educación británica. Y me anima a desaprender lo mal aprendido en el cole y a arriesgarme con ustedes a renovarnos hasta encontrar nuestra propia zona,nuestro mentor y tribu creativa, para alcanzar la misma e intensa conexión con la vida que gozaron Einstein o Mozart.
Un día visitando un cole vi a una niña de seis años concentradísima dibujando. Le pregunté: "¿Qué dibujas?". Y me contestó: "La cara de Dios".
¡...!
"Nadie sabe cómo es", observé. "Mejor - dijo ella sin dejar de dibujar-,ahora lo sabrán".

Todo niño es un artista. 
Porque todo niño cree ciegamente en su propio talento. La razón es que no tienen ningún miedo a equivocarse... Hasta que el sistema les va enseñando poco a poco que el error existe y que deben avergonzarse de él.

Los niños también se equivocan. 
Si compara el dibujo de esa niña con la Capilla Sixtina, desde luego que sí, pero si la deja dibujar a Dios a su manera, esa niña seguirá intentándolo. El único error en un colegio es penalizar el riesgo creativo.

Los exámenes hacen exactamente eso.
No estoy en contra de los exámenes, pero sí de convertirlos en el centro del sistema educativo y a las notas en su única finalidad. La niña que dibujaba nos dio una lección: si no estás preparado para equivocarte, nunca acertarás, sólo copiarás. No serás original.

¿Se puede medir la inteligencia? 
La pregunta no es cuánta inteligencia, sino qué clase de inteligencia tienes. La educación debería ayudarnos a todos a encontrar la nuestra y no limitarse a encauzarnos hacia el mismo tipo de talento.

¿Cuál es ese tipo de talento? 
Nuestro sistema educativo fue concebido para satisfacer las necesidades de la industrialización: talento sólo para ser mano de obra disciplinada con preparación técnica jerarquizada en distintos grados y funcionarios para servir al Estado moderno.

La mano de obra aún es necesaria. 
¡Pero la industrialización ya no existe! Estamos en otro modo de producción con otros requerimientos, otras jerarquías. Ya no necesitamos millones de obreros y técnicos con idénticas aptitudes, pero nuestro sistema los sigue formando. Así aumenta el paro.

Pero se nos repite: ¡innovación! 
La piden los mismos que la penalizan en sus organizaciones, universidades y colegios. Hemos estigmatizado el riesgo y el error y, en cambio, incentivamos la pasividad, el conformismo y la repetición
No hay nada más pasivo que una clase. 
¿Es usted profesor, verdad? Las clases son pasivas porque los incentivos para estar calladito y tomar apuntes que repetirá son mayores que los de arriesgarse a participar y tal vez meter la pata. Así que, tras 20 años de educación en cinco niveles que consisten en formarnos para unas fábricas y oficinas que ya no existen, nadie es innovador.

¿Cuáles son las consecuencias? 
Que la mayoría de los ciudadanos malgastan su vida haciendo cosas que no les interesan realmente, pero que creen que deben hacer para ser productivos y aceptados. Sólo una pequeña minoría es feliz con su trabajo, y suelen ser quienes desafiaron la imposición de mediocridad del sistema.

Tipos con suerte... 
Son quienes se negaron a asumir el gran error anticreativo: creer que sólo unos pocos superdotados tienen talento.

"Sé humilde: acepta que no te tocó". 
¡Falso! ¡Todos somos superdotados en algo! Se trata de descubrir en qué. Esa debería ser la principal función de la educación. Hoy, en cambio, está enfocada a clonar estudiantes. Y debería hacer lo contrario: descubrir qué es único en cada uno de ellos.

¿La creatividad no viene en los genes?
Es puro método. Se aprende a ser creativo como se aprende a leer. Se puede aprender creatividad incluso después de que el sistema nos la haya hecho desaprender.

Por ejemplo... 
Soy de Liverpool y conozco el instituto donde recibieron clases de música mi amigo sir Paul McCartney y George Harrison... ¡Dios mío! ¡Ese profesor de música tenía en su clase al 50 por ciento de los Beatles! 

Y... 
Nada. Absolutamente nada. McCartney me ha explicado que el tipo les ponía un disco de música clásica y se iba a fumar al pasillo.
A pesar del colegio, fueron genios.
A Elvis Presley no lo admitieron en el club de canto de su cole porque "desafinaba". A mí, en cambio, un poliomielítico, me admitieron en el consejo del Royal Ballet...

Ahí, sir, acertaron de pleno. 
Allí conocí a alguien que había sido un fracaso escolar de ocho años. Incapaz de estar sentada oyendo una explicación.

¿Una niña hiperactiva? 
Aún no se había inventado eso, pero ya se habían inventado los psicólogos, así que la llevaron a uno. Y era bueno: habló con ella a solas cinco minutos; le dejó la radio puesta y fue a buscar a la madre a la sala de espera; juntos espiaron lo que hacía la niña sola en el despacho y... ¡estaba bailando!

Pensando con los pies. 
Es lo que le dijo el psicólogo a la madre y así empezó una carrera que llevó a esa niña, Gillian Lynne, al Royal Ballet; a fundar su compañía y a crear la coreografía de Cats o El fantasma de la ópera con Lloyd Webber.

Si hubiera hecho caso a sus notas, hoy sería una frustrada. 
Sería cualquier cosa, pero mediocre. La educación debe enfocarse a que encontremos nuestro elemento: la zona donde convergen nuestras capacidades y deseos con la realidad. Cuando la alcanzas, la música del universo resuena en ti, una sensación a la que todos estamos llamados.

Sir Ken Robinson: "¿Los colegios acaban con la creatividad?"

TED 2014: Larry Page on Google's robotic future

 
Larry Page was interviewed at Ted by US television host Charlie Rose


Larry Page wants patients to hand over their data to researchers in order to save "100,000 lives".

It's just one of the ideas expressed in a wide-ranging interview at the Ted (Technology, Entertainment and Design) conference in Vancouver.

Google's co-founder criticised the US government for its mass surveillance programs.

But he added that consumers need to accept that a new era of open data is inevitable. Smarter computers

Interviewed on the Ted stage by US television host Charlie Rose, Mr Page was asked why Google bought the UK machine learning firm DeepMind.

"I was looking at search and trying to understand how to make computers less clunky and also thinking about how speech recognition is not very good," said Mr Page.

"We are still at the very early stages with search. Computers don't know where you are and what you are doing," he added.

He was drawn to DeepMind because it had helped make computers smarter - teaching them how to play computer games.

"It was really exciting, we have not been able to do this before. Imagine if that intelligence is thrown at your schedule," said Mr Page.

He said that Google was working on its own machine learning project, using YouTube to "teach" computers.

"It has learnt what cats are," he said. Tremendous disservice

Mr Page was also asked about the Edward Snowden revelations, following a surprise appearance from the whistle-blower at Ted.

"It is disappointing that the government secretly did this stuff and didn't tell us about it," said Mr Page.

"It is not possible to have a democracy if we have to protect our users from the government. The government has done itself a tremendous disservice and we need to have a debate about it," he added.

Google has had its fair share of criticism for the way it collects users data. It is currently embroiled in row with European regulators over its privacy policy.

Mr Page was in defiant mood and warned that people were at risk of "throwing out the baby with the bathwater" over plans to tighten privacy.

"We are not thinking about the tremendous good that can come with sharing information with the right people in the right ways," he said.

He said that anonymised medical records should be made available to researchers.

"It could save 100,000 lives this year," he said.

Health data has personal resonance with Mr Page who developed a hoarse voice after a cold 15 years ago from which he has never recovered. Sharing details about his condition helped him, he said.

"I was scared to share but Sergey [Brin] encouraged me and we got thousands of people with similar conditions," he said. Gaining space

Mr Page also talked about some of his "crazy ideas", including Google Loon, a project to use balloons to provide internet access to parts of the world without any.

He revealed that he got the idea off the ground with a Google search.

"I found that 30 years ago someone had put up a balloon and it had gone round the world multiple times," he said.

He realised that a similar thing was possible to connect the two-thirds of the world that have no net access.

"We can build a world-wide mesh of balloons to cover the whole planet."

Google plans to launch its automated cars on the roads by 2017. The project has been a personal obsession for 18 years, he told the Ted audience.

"It started when I was at college in Michigan. I was waiting for the bus and it was cold and snowing," he said.

He believes that automated cars can help save lives - currently 20 million people are injured each ear in car accidents and in the US crashes are the biggest cause of death for the under 35s.

He finished the interview with a call to firms to embrace new technologies.

"Most businesses fail because they miss the future," he said.

It is a mistake he has made himself, he added.

He said that he "felt guilty for wasting time" working on the Android operating system, which at the time was a side project for Google.

"That was stupid, it was the future," he said.

Wolves will travel to drink from a river. But could the presence of wolves lead a river to change its behavior?

George Monbiot: For more wonder, rewild the world

In his TED Talk, George Monbiot poetically explains how reintroducing wolves to Yellowstone National Park after a 70-year absence set off a “trophic cascade” that altered the movement of deer, sent trees soaring to new heights, attracted scores of new animals to the area (think: beavers, rabbits, bears, bald eagles and more), and stabilized the banks of rivers making them less susceptible to erosion. Above, see that story set to music — and howls — by SustainableMan.org, who took the audio track from the talk and laid it over beautiful nature footage. It’s a glorious glimpse of how deeply the natural world is interconnected.

If you love this short video, definitely check out Monbiot’s whole TED Talk too. In the talk, he shares some ways we can get more involved in the re-wilding of the world … and why it matters to all of us.

A needle-free vaccine patch that's cheaper than a needle

One hundred sixty years after the invention of the needle and syringe, we're still using them to deliver vaccines; it's time to evolve. Biomedical engineer Mark Kendall demos the Nanopatch, a one-centimeter-by-one-centimeter square vaccine that can be applied painlessly to the skin. He shows how this tiny piece of silicon can overcome four major shortcomings of the modern needle and syringe, at a fraction of the cost.

Biodiesel: The afterlife of oil

How could you dispose of your cooking oil when you're done cooking? The easiest thing to do might be to pour it down your drain -- but if you save it up and send it to a processing plant, it can gain useful new life as biodiesel, a biodegradable energy source which can run in diesel engines instead of refined petroleum. Natascia Radice describes the process of turning goop into good.

This is what happens when a kid leaves traditional education

When 13 year-old Logan LaPlante grows up, he wants to be happy and healthy. He discusses how hacking his education is helping him achieve this goal.

"... for better or worse much of Education is oriented towards making a living rather than making a life..."
"...a lot of people think of hackers as geeky computer nerds who live in their parents basement and spread computer viruses but I'll see it that way. Hackers are innovators, hackers are people who challenge and change the system's to make them work differently to make them work better it's just how they think. It's a mindset. I'm going up in a world that needs more people with the hacker mindset..."

Our Woman of the Forest: Jane Goodall Speaks at TED

This video of Dr.Jane Goodall is a few years old but it is extremely important to anyone who has an interest in field biology, animal and habitat conservation, primatology, humanism, or the history of science.

I should actually write the living history of science since Dr. Goodall, who at 79-years-old, is still with us and is as active as ever.

Through her presentations and her foundation, The Jane Goodall Institute, she and others are helping to save wild chimpanzees from extinction as well as save what is left of their habitat from deforestation.

Here is her powerful TED Talk (c. 2002):


I am amazed and pleased by her rather jolly attitude. But the light flutter of her speech pattern should not be discounted as she is a very deep thinker. After a lifetime of living amongst and studying human and non-human primates, she is an activist with a profound message to bring forward.

In this less than half-hour video, she shares her many passions and as a very serious woman who has some very serious stuff to say, explains concisely what it means to be both human and humane. Here is just one poignant section:

"We see deforestation; we see the desert spreading; we see massive hunger; we see disease and we see population growth in areas where there are more people living on a certain piece of land than the land can possibly support, and they're too poor to buy food from elsewhere. Were the people that we heard about yesterday, on the Easter Island, who cut down their last tree -- were they stupid? Didn't they know what was happening? Of course, but if you've seen the crippling poverty in some of these parts of the world it isn't a question of "Let's leave the tree for tomorrow." "How am I going to feed my family today? Maybe I can get just a few dollars from this last tree which will keep us going a little bit longer, and then we'll pray that something will happen to save us from the inevitable end." So, this is a pretty grim picture."

Grim yes. But overall this is a very positive presentation.

Enjoy!

Two young scientists break down plastics with bacteria

Miranda Wang and Jeanny Yao have identified a new bacteria that breaks down nasty compounds called phthalates, common to flexible plastics and linked to health problems. And they’re still teenagers.

Why you should listen to them:
After a visit to a plastic-filled waste transfer station last year, students Miranda Wang and Jeanny Yao learned that much of the plastic in trash may not degrade for 5,000 years. Synthesized into plastics are phthalates, compounds that make shower curtain liners, food wraps and other products bendable but may also adversely impact human reproductive development and health. As plastics slowly break down, these phthalates would leach into the surrounding environment.

So, the two young scientists tackled the problem and ultimately discovered strains of bacteria that have the potential to naturally degrade phthalates. Their work earned a regional first place in British Columbia for the 2012 Sanofi BioGENEius Challenge Canada, as well as a special award for the most commercial potential at the contest’s finals.

"[Wang and Yao] came up with the research idea and the underlying experimental design, which is remarkable for such young people."

3D Printed Robotic Arm: Colorado Teen Designs $500 Prosthetic Controlled By Bluetooth Headband

ORIGINAL: IB Times
By Ryan W. Neal
August 15 2013

A Colorado teenager has used 3D printing to create a robotic prosthetic arm that costs less than $500 and is fully functional. YouTube
A Colorado teenager has used 3D printing to create a robotic prosthetic arm that costs less than $500 and is fully functional. At Denver's TedxMileHigh, Easton LaChappelle, 17, demonstrated his robotic arm, and how he constructed it to keep the cost low.

LaChappelle said he came up with the idea for a robotic arm when he was 14, then turned to the Internet to teach himself the engineering and programming skills needed to execute it. When the costs involved in making a full-size arm became too great, LaChappelle looked into 3D printing.

So, in the end, I built this robotic arm up to the shoulder, which was extremely strong,” LaChappelle said. “It could toss balls to you, it could shake your hand, it could pretty much do anything a human could if you program it correctly."

Related
LaChappelle entered his robotic arm in the Colorado Science and Engineering Fair, where he met a 7-year-old girl with a prosthetic arm that cost $80,000. LaChappelle decided to add a control system to the robotic arm and direct his fun project toward helping people.

Instead of neural sensors implanted in a spinal cord, LaChappelle wanted a control system that was external so it could be taken on and off. LaChappelle’s prosthetic arm is controlled with an electroencephalographic headband, which can read about 10 different channels of the brain and communicate with the arm wirelessly via Bluetooth technology.

LaChappelle said 3D printing was essential not only in building custom gears and prototypes at comparatively low cost but also in allowing him to construct a prosthetic arm that looks relatively organic. LaChappelle used acetone vapor on the 3D-printed hand to give it a clean, glossy finish.

LaChappelle’s work with the 3D-printed prosthetic arm landed him a job working at NASA on the Robonaut team. He's now engaged in producing a set of robotic legs for a classmate who can’t walk.

Advances in 3D printing technology are making huge waves for people with disabilities. At a recent Wearable Technology Conference in New York, a hat designed to help a person with hearing loss won recognition as the best in show, while 3D printing was also used to produce a prosthetic foot for a duck. In Europe, a set of robotic legs became the first robotic apparatus approved as a medical device there.

Michael Green: Why we should build wooden skyscrapers


ORIGINAL: TED




Michael Green wants to solve architecture’s biggest challenge -- meeting worldwide housing demand without increasing carbon emissions -- by building with carbon-sequestering wood instead of concrete and steel.

Michael Green: Architect
Why you should listen to him: Michael Green is calling for rapid systemic change in the way we build. To end the global housing and climate crises, we need to get past innovation-stifling regulations and well-meaning but misguided ideas popularized by mainstream media. His proposal: Forget steel, straw, concrete, shipping containers, and rammed earth. Use wood to erect urban skyscrapers. “When the Eiffel Tower was built, nobody thought it could be done. Now it’s a symbol of Paris,” Green told the Vancouver Sun. “Projects like it really triggered an innovation on how cities were built. Man moves by innovation and [by] aiming for the moon.

Green, whose projects range from retail boutiques and housing in North America to a sustainable community in Asia, explores the plausibility of tall wood buildings -- the costs, benefits, and engineering challenges -- in an extensive 2012 white paper. The TED Talent Search winner also teaches and mentors at the University of British Columbia’s School of Architecture and Landscape Architecture (SALA).

5 teenage cancer innovators

ORIGINAL: TED Blog
TED BlogHealthTEDTalks


by: Kate Torgovnick
July 25, 2012



Some teenagers spend their free time playing video games. Others dedicate their after-school hours to a job, scooping ice cream or taking movie tickets. Still others play a sport, or are star members of a debate team. And still others spend their free time in a lab, working on ways to prevent, diagnose and treat cancer.

In a talk posted on TED.com earlier this week, 16-year-old Jack Andraka shares what got him interested in studying pancreatic cancer — a close family friend succumbing to the disease in just three months time. Pancreatic cancer is brutal, with only 5.5% of those diagnosed surviving past five years — in part because it is usually diagnosed very late. After Googling and finding terrifying statistics on the disease, Andraka had an idea: could there be a noninvasive test for pancreatic cancer to diagnose it early?

In this charming talk, Andraka reveals the many lightbulb-over-head moments that led him to create a test for pancreatic cancer that costs three cents and is close to 100% accurate. It’s a must-hear story, as one can imagine this test someday being given during routine checkups, if all goes as planned.

(Read the TED Blog’s Q&A with Andraka about his research, his friendly sibling rivalry, and how long it would be before the test is available.)

Here, talks from four more incredible young people who’ve taken the TED stage to talk about their cancer research.


Eva Vertes: Do stem cells cause cancer?
Microbiology prodigy Eva Vertes was only 19 years old when she spoke at TED2005 about cancer stem cells. In the talk below, she presents research that suggests cancer might be a repair response to damage to stem cells in the lungs, liver, bones, etc. The implication she is testing? “It’s possible, although far-fetched, that in the future we could think of cancer being used as a therapy,” she explains in the talk below.


Lauren Hodge and Shree Bose: Award-winning teen-age science in action
At the 2011 Google Science Fair, three young women swept the top prizes. The trio presented their award-winning projects at TEDxWomen that year. Then-13-year-old Lauren Hodge studied the formation of carcinogens in cooking chicken and found a surprising result — that maybe you don’t really want the grilled chicken after all. Meanwhile, Shree Bose researched how chemotherapy resistance happens in ovarian cancer — a breakthrough that could improve future treatments. Watch both young women present their findings below.


Brittany Wenger: A cloud to diagnose breast cancer
Brittany Wenger taught a computer to diagnose breast cancer, a feat that required 600 hours of coding as well as the running of 7.6 million trials, before she was even old enough to vote. “I started in the 7th grade,” Wenger, who won Google’s International Science Fair in 2012, told ScientificAmerican.com. “I want to be on the frontier of cancer research, finding the cures that are going to save lives and doing things with computer science that can be the technologies of the future.

Wenger, who spoke at TEDxWomen 2012, started this project with a computer programming book and zero experience. Soon, she had the idea to create an artificial neural network, a program that learns as it encounters more data, and train it to differentiate between benign and malignant breast tissue. The data came from fine needle aspirates, currently the least invasive but also the least conclusive test for breast cancer. Wenger’s network, Cloud4Cancer, is 99.1% sensitive to malignancies and, as it learns more, should only get better. Soon, Wagner hopes to open up the network to hospitals and, with more research, the least invasive test for breast cancer could become the most accurate.

This post originally ran on July 25, 2012, as Brittany Wenger was announced as winner of the Google Science Fair. It was revised on July 12, 2013, when Jack Andraka’s talk was posted.

Skylar Tibbits: The emergence of "4D printing"

ORIGINAL: TED
TED2013
Apr 2013

3D printing has grown in sophistication since the late 1970s; TED Fellow Skylar Tibbits is shaping the next development, which he calls 4D printing, where the fourth dimension is time. This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time. Think: a printed cube that folds before your eyes, or a printed pipe able to sense the need to expand or contract.

Skylar Tibbits, a TED Fellow, is an artist and computational architect working on "smart" components that can assemble themselves.

Why you should listen to him:

Can we create objects that assemble themselves -- that zip together like a strand of DNA or that have the ability for transformation embedded into them? These are the questions that Skylar Tibbits investigates in his Self-Assembly Lab at MIT, a cross-disciplinary research space where designers, scientists and engineers come together to find ways for disordered parts to become ordered structures.

A trained architect, designer and computer scientist, Tibbits teaches design studios at MIT’s Department of Architecture and co-teaches the seminar “How to Make (Almost) Anything” at MIT’s Media Lab. Before that, he worked at a number of design offices including Zaha Hadid Architects, Asymptote Architecture, SKIII Space Variations and Point b Design. His work has been shown at the Guggenheim Museum and the Beijing Biennale.

Tibbits has collaborated with a number of influential people over the years, including Neil Gershenfeld and The Center for Bits and AtomsErik and Marty Demaine at MIT, Adam Bly at SEED Media Group and Marc Fornes of THEVERYMANY. In 2007, he and Marc Fornes co-curated Scriptedbypurpose, the first exhibition focused exclusively on scripted processes within design. Also in 2007, he founded SJET, a multifaceted practice and research platform for experimental computation and design. SJET crosses disciplines from architecture and design, fabrication, computer science and robotics.

"The big idea is to create objects that can change after they are printed, making them self-adapting. The act of printing is no longer the end of the creative process but merely a waypoint."


Quotes by Skylar Tibbits
There’s new possibilities for self-assembly, replication, repair in our physical structures, our buildings, machines. … Imagine if our buildings, our bridges, machines, all of our bricks could actually compute.” Watch this talk »
