You’re a Wonder: How Your Ear Works

By:

Why temporary deafness is good for you, or what sound waves have to do with the smallest bone in the body.

Yesterday, mathemagician Vi Hart dazzled us with math of noises and science of sound, frequency and pitch. Today, we turn to a complementary short excerpt from BBC’s fascinating Inside the Human Body series, explaining the marvel of human hearing. Listen and learn.

Do You See What I See? BBC on the Subjectivity of Color Perception

By:

Why you should wear red on your next date, or what an African tribe can teach us about the color of water.

We’ve previously examined the extreme ends of how the brain perceives color, from Ben Lotto’s remarkable optical illusions to the curious neurological short-circuiting known as synesthesia. But how do “normal” people see “normal” color? Turns out, the answer isn’t as black and white. From the fine folks behind BBC’s excellent Horizon series — who have also pondered the nature of reality, the age-old tension between science and religion, how music works, what time is, and how money came to dominate the world — comes Do You See What I See, a fascinating look at the subjectivity and divergence of how we each see the world and the surprising power colors can have on our mood, cognition, emotion, and entire lives.

The hour-long program explores a number of psychology and neuroscience experiments exploring everything from how the color red suppressed the stress-hormone cortisol to elevated confidence to how blue changes our sense of time to make a minute feel 11 seconds shorter to how language shapes the perception of color in different cultures. (Though it should be noted that, while presented as new, the findings are based on the pioneering work of Paul Kay and Brent Berlin, circa 1969.)

Your eye doesn’t simply see color — your brain creates it by drawing on knowledge of what things should look like.”

The earliest colors we learned — blue and yellow — have hard-wired emotional connections. Our associations with red and green we’ve had to learn.”

For more on the science of color perception, you won’t go wrong with Mark Changizi’s fantastic The Vision Revolution: How the Latest Research Overturns Everything We Thought We Knew about Human Vision and the out-of-print but excellent Color Perception: Philosophical, Psychological, Artistic, and Computational Perspectives from Oxford University Press.

Ai Weiwei: Without Fear or Favour, a BBC Documentary

By:

Exploring the role of art as an agent of change, or what 100 million porcelain seeds have to do with Twitter.

Creative visionary, political activist and post-modern Renaissance man Ai Weiwei is China’s most widely known and politically vocal contemporary artist. His now-legendary Sunflower Seeds installation for the Tate Modern in October 2010, which took 2.5 years and 1,600 Chinese artisans to produce 100 million hand-crafted sunflower seeds from the finest Chinese porcelain, offered powerful commentary on consumerism, Chinese industry, human rights and collective labor. In February 2011, a 220-pound pile of the seeds sold for $559,394 at Sotheby’s in London. On 3 April, 2011, Ai Weiwei was detained under harsh conditions for over two months without any official charges being filed, on allegations of “economic crimes.”

On June 22 2011, following a large and sustained outcry by international human rights organizations and prolific Western media coverage, the Chinese government released Ai Weiwei on bail, under a number of conditions. But the controversy surrounding his work and the provocative political questions raised by his arrest remain an important part of the global dialogue on art, activism and freedom of speech.

He uses the publicity he gets in a very knowing way, and he uses exhibitions and projects, like the Bird’s Nest stadium, as a platform to be visible and to be able to turn them against themselves. And that’s extremely interesting, and a very sophisticated way of being an artist.”

This fascinating hour-long documentary titled Ai Weiwei: Without Fear or Favour, released by BBC One’s Imagine program earlier this year and recorded shortly prior to Ai Weiwei’s arrest, helps contextualize his work, its cultural significance and its implicit political tensions. Ironically, the film — which deals with issues of openness, censorship and accessibility — is not viewable outside the U.K. thanks to BBC’s restrictive digital media policies, but it’s available on YouTube in its entirety, at least for the time being, thanks to what seems to be Ai Weiwei’s own Chinese YouTube account. Enjoy.

Ai Weiwei is, to my mind, the most significant Chinese artist we are aware of in the West. He’s articulate, he’s passionate, he goes to the edge, he’s unafraid of criticizing the politics and the situation in his own country, nor indeed is he afraid of criticizing Western capitalism.”

For more on Ai Weiwei, his work and convictions, look no further than the excellent Ai Weiwei’s Blog: Writings, Interviews, and Digital Rants, 2006-2009, culled from the salvaged archive of the artist’s blog, which was taken down by the Chinese authorities in 2009. Courageous, honest and effusively eloquent, Ai Weiwei’s writing offers a rare lens on the mental and physical state of present-day China, the role of contemporary art in politics, and the role of the artist as an agent of change.
