(R)evolutionary Record: The Darwin Song Project

By:

Under house arrest by art and science, or what evolution has to do with independent music.

You may have forgotten Charles Darwin’s birthday — he turned 200 in February — but you still have a chance to commemorate it. Recently, Neil Pearson, owner of Fish Records and director of the UK’s Shrewsbury Folk Festival, persuaded 8 of Britain’s finest singer-songwriters to visit Darwin’s farm house. Little did they know he’d lock them inside for one week and have them create an album from scratch, dedicated to the life and work of the eminent evolutionist.

What has emerged is a juicy mix of storytelling and incredible talent, dubbed the Darwin Song Project.

British singer/songwriter and multinstrumentalist Jez Lowe, for instance, found inspiration in Darwin’s personal affairs: His wife, Emma, with whom he never seemed to agree, always wanted to spend more time with her husband, who spent countless hours away from Emma on his work, Voyage of The Beagle. They differed on many levels, particularly in the clash between Emma’s belief in God and Charles’ evolutionary theory. Lowe writes,

Where’ve you been, your tea’s been in the oven. Come home now.

Other artists include Rachael McShane, Stu Hanna, Emily Smith, Chris Wood, Mark Erelli, Karine Polwart and Krista Detor — and they seem to have had a blast collaborating. Catch their reflections on the experience here and here.

Originally created for a live concert at Theatre Severn in March, the music from the project will be released as an album this summer. The group will also reconvene to perform at the Shrewsbury Folk Festival in late August.

Stay tuned on the project’s website.

Update: The album is now out, and it’s every bit as fantastic as we’ve come to expect it to be. Grab a copy.

Truth, Beauty, Math and Crocheting

By:

Why your grandmother’s favorite pastime proves mathematicians are a bunch of clueless hacks.

Science writer Margaret Wertheim and her twin sister Christine are on a crusade to correct the longest-running errors of science through art. Their weapon? Crocheting.

They are the founders of the Institute For Figuring — an exploration of the aesthetic and poetic dimensions of science and mathematics. It’s part mathematics, part feminine handicraft, part marine biology and part environmental activism. And it also happens to be a defining pillar of our mathematical understanding of nature.

So why crocheting?

For a very scientific reason, actually: The peculiar structure typical of corals and sponges is a special form of geometry known as hyperbolic geometry, which just so happens to be the bane of mathematicians’ existence — it’s near-impossible to model on a computer, and the most accurate way mathematicians have of modeling it is through crocheting.

And even that took scientists nearly 2 centuries to figure out — until the discovery of hyperbolic geometry in the 19th century, there were only two kids of space conceivable:  Euclidean, or flat space, and spherical. But it wasn’t until 1997 that the crochet modeling method was discovered by  a mathematician at Cornell, disproving the most fundamental axiom of mathematics — Euclid’s Parallel Postulate.

So here in wool, through domestic feminine art, is the proof that the most famous postulate of mathematics is wrong.

In fact, species like sea slugs have existed for millions of years, happily violating the very principle Euclid claimed was impossible to violate — something mathematicians had previously chosen to conveniently overlook. Crocheting these structures offered not only a new model of geometric representation, but also a whole new model of thinking: This sort of non-euclidean geometry is actually the very foundation of the theory of relativity, thus the closest thing we have to an understanding of the shape of the universe.

The project began in 2005, the first year that global warming really became an issue of global concern for both the science community and the enlightened general public. Coral reefs, which are incredibly delicate organisms, are among the species most severely affected by global warming — any rise in sea temperatures causes vast bleaching events, which inevitably kill entire coral colonies.

But perhaps most fascinatingly, the project serves as a brilliant allegory for the evolution of life on earth. Originally a centralized effort by the Wertheim sisters, the IFF began to attract outside contributions from people all over the world. Today, it has evolved into a global collaboration of science-minded craft-masters, who have contributed tens of thousands of hours worth of human labor totaling thousands of coral models — a truly grassroots exploration of our collective understanding of marine biology and mathematics.

Algebraic representations, equations, codes… We live in a society that’s obsessed with presenting information in this way, teaching information in this way. But through this form of modeling, people can be engaged with the most abstract, high-power, theoretical ideas.

Werheim is particularly passionate about the play-based explorations of concepts, stressing the importance of creating “play tanks” in a society dominated by think tanks — great minds who think about the world and write grand symbolic treaties about it, but don’t engage with great ideas on the highest abstract level.

Watch Wertheim’s fantastic TED talk, where she reveals a glorious intersection of beauty and math.

TED 2009 Highlights: Day 2

By:

Lots and lots (and lots) of brilliance, wrapped in fascination and tied with a shiny ribbon of sheer jaw-droppingness.

Despite our sleep-deprived state, we managed to live-blog our way through another day of TED. Well, sort of — the guys at Long Beach had severe technical difficulties on their end, which sort of reduced TED to ED for a couple of hours.

Oliver Sacks But sleeplessness and glitches notwithstanding, it was a phenomenal day embezzled with a number of well-deserved standing ovations. Neurologist extraordinaire Oliver Sacks opened the See session with a fascinating talk about a specific kind of visual hallucinations in perfectly sane blind patients, called Charles Bonnet syndrome, which occur because visual receptors become hyperactive when they receive no real input. Apparently, over 10% of blind people get this, but only about 1% ever acknowledge it in fear of being ridiculed and perceived as insane — what a stark reminder of the clash between cognitive health and social health.

UCSB researcher JoAnn Kuchera-Morin followed, introducing perhaps the most fascinating piece of the night: The AlloSphere machine, a “scientific data discovery and artistic creation tool.” She proceeded to show phenomenal imagery, including the AlloBrain — a project that builds medical narrative through real fMRI data mapped sonicly and visually, with tremendously rich potential for medical application.

Allosphere

Also shown: the multi-center hydrogen bonds of a new material used for transparent solar cells, a clearly gigantic stride for clean energy. The footage itself was absolutely stunning, especially framed in the knowledge that it’s all real, not a CGI simulation.

Electron spin

Another visually and conceptually captivating talk came next, with light and space sculptor Olafur Eliasson. He tossed the audience into a visual experiment right there on the stage screen, demonstrating the link between eye and brain in a very raw, tangible way before introducing his equally compelling work — work that is, above all, creating a sense of consequence by making space accessible and instilling in people a sense of community and togetherness.

Olafur Eliassion: Work

Olafur’s entire talk was a string of eye-opening epiphanies on the nature of art, our relationship to the world and each other, our shared sense of responsibility.

Art is obviously not just about decorating the world, but also about taking responsibility.

True that.

Ed Ulbrich was next, with perhaps the biggest shock-value jaw-dropper of the night: He took us behind the scenes of The Curious Case of Benjamin Button, revealing that Brad Pitt’s character was actually entirely computer-generated from the neck up. Crafting it was so laborious that just the person responsible for the character’s eye system spent over two full years on it. (Pause on that for a moment.)

They also had to create every possible lighting condition for the character, in order to make him appear realistic and believable in all scenes.

Benjamin Button: Lighting conditions

Their biggest challenge was animating facial emotion. Traditionally, facial animation is done by recording the motion on 100 surface polygons, with 100 tracking points. But they found that the richest emotional information came from the stuff between the points. So, unsurprisingly to us, they turned to one of our greatest heroes: Paul Ekman and his brilliant Facial Action Coding System.

Setting up a system of 3D cameras, they were able to record a surface of over 100,000 polygons, tracking 10,000 points.

We ended up calling the entire process “emotion capture” rather than “motion capture.”

In the end, Ulbrich made an excellent point that most of us hardly give much thought to: Despite the technological advances and the computer-generated character, animating it still fell on Brad Pitt’s unique acting skill and dramatic capacity — because the Button character, tech smoke-and-mirrors notwithstanding, is but a digital puppet to be operated entirely by its actor-puppeteer.

GolanLevin Closing the See session was experimental audio-visual artist Golan Levin, who introduced a mind-blowing subtitling technology that animates text with the amplitude, pitch and frequency of the speaker’s voice, so that the text literally becomes alive with meaning. Levin also revealed his fascination with the human gaze, introducing a revolutionary eye-tracking system aimed at making the computer aware of what it is looking at and able to respond.

Golan Levin: eye-tracking

What if art was aware we were looking at it, how could it respond?

He proceeded to show off another rather peculiar (by which we mean creepy-cool) extension of the technology: The Double-Taker, an enormous eye of a snout that follows a person as he or she moves through space, in a very organic albeit creepy way.

Golan Levin: Double-Taker

And although we were teched out of much of the Understand session that followed, regretfully missing anthropologist Nina Jablonski‘s much- anticipated talk, we did catch Elizabeth Gilbert‘s profound insight on the paradox of the creative process, which is always inevitably tied to anguish as artists fear being unable to outdo themselves creatively.

The final session, Invent, opened with iconic yet controversial architect Daniel Libeskind, whose reconstruction plan for Ground Zero was the people’s choice, but was tragically crushed by commercial pressures and had to give way to the current winner. Libeskind talked about the clash between hand and computer, pointing out the challenge of making the computer respond to the hand rather than vise-versa.

Daniel Libeskind: Work

Showcasing some of his phenomenal commercial and concept work, he raised deeper questions about the role of architecture in the human story.

Architecture is not only the giving of answers, it’s also the asking of questions.

Shai Agassi Green auto pioneer Shai Agassi followed. Besides showing the enormity of the scale, on which cars impact the world, he also drew a rather brilliant analogy: Before the Industrial Revolution, much of the U.K.’s labor force came from an immoral element — human slaves. And as soon as slavery ended, the Industrial Revolution began. We are, in effect, getting much of our energy from an immoral source, subjecting the planet to a form of slavery. Ending “planetary slavery” is the only way to the next social revolution.

True that.

The remaining talks showcased a broad range of truly revolutionary innovation in robotics and medicine, from Catherine Mohr‘s amazing surgical robots, to Robert Full‘s brilliant technology simulating the toe-peeling and air-righting of the gecko, to Daniel Kraft‘s Marrow Miner tool that bypasses transplant pain by allowing local anaeshtesia, harvesting 10 times more marrow.

Finally, polymorphic playwright Sarah Jones, one of the best entertainers to ever hit TED stage, closed the session with her truly — truly — captivating performance of her array of characters, each of whom she channels to an unbelievable level of believability. That’s one talk you’d want to see when it becomes available.

TED Prize 2009 Winners The last segment was the awarding of this year’s TED Prize, the streaming of which was accessible to everyone online and available in select theaters across the U.S. The winners — marine preservation advocate Sylvia Earle, space explorer Jill Tarter, and music education pioneer José Abreu — are every bit as deserving as you’d expect, so be sure to check out their wishes — and if you’re passionate about that field, you can even offer help to each of the three on his or her TED Prize page.

We’ll be live-blogging today as well, so be sure to follow us on Twitter if you’re into, you know, hearing stuff before everyone else does.

The Sky in Motion: 7,000 NASA Images in a Mesmerizing Timelapse

By:

The Earth, the Moon, the stars, and the joys of geekdom.

This being the International Year of Astronomy and all, we thought it would be kind of nice to swap the daily screen stare for a wide look at the open skies. Granted, we can’t really do that, but we can try to do both.

The Sky in Motion is a fascinating, hypnotic project featuring several time-lapse videos, each composed of over 7,000 images revealing the richness of our skies. Featured in NASA‘s Astronomy Picture of the Day, this video blends the romantic obsession over the Moon, the Sun and the stars with the scientific awe of meteors, satellites, and crepuscular rays — all framed by the wonder of Earth’s own rotation. 


Seems like NASA has come a long way from those laughable times we shall not speak of again.

Thanks, @guykawasaki.
