What sound looks like … in GIFs: TEDx speaker Fabian Oefner visualizes sound
Above, GIFs from photographer (and TEDxWarwick speaker) Fabian Oefner’s talk at TEDGlobal 2013, “Psychedelic science.”
Says Fabian of his work:
Sound travels in waves, so if you have a speaker, a speaker actually does nothing else than taking the audio signal, transform it into a vibration, which is then transported through the air, is captured by our ear, and transformed into an audio signal again.
Now I was thinking, how can I make those sound waves visible? So I came up with the following setup. I took a speaker, I placed a thin foil of plastic on top of that speaker, and then I added tiny little crystals on top of that speaker. And now, if I would play a sound through that speaker, it would cause the crystals to move up and down. Now this happens very fast, in the blink of an eye, so, together with LG, we captured this motion with a camera that is able to capture more than 3,000 frames per second.
This is what that looks like. As Bill Nye says, "Science rules!"
In only a few decades, this capital has transformed itself from an impoverished city decimated by the Korean War to one of the most prosperous and high-tech places in the world. In the past decade there’s also been an explosion of international interest in Korean popular culture, especially catchy K-pop music, soapy TV dramas and edgy cinema, making the most famous Korean singers, stars and directors household names everywhere from Tokyo to Beijing. Koreans even have a name for this blossoming of foreign interest in their homegrown pop culture: hallyu, which means Korean wave. Korea has long been dwarfed by China and Japan, far more populous nations that have colonized the Korean Peninsula, and so this recent cultural hegemony has given Seoul residents a newfound confidence, even exuberance, in their city. - Continue reading at Smithsonian.com.

Here’s to you, Charlie Parker! In honor of his birthday, check out this documentary about the jazz legend.
The best man is like water.
Water is good; it benefits all things and does not compete with them.
It dwells in lowly places that all disdain.
This is why it is so near to Tao.
The best man in his dwelling loves the earth.
In his heart, he loves what is profound.
In his associations, he loves humanity.
In his words, he loves faithfulness.
In government, he loves order.
In handling affairs, he loves competence.
In his activities, he loves timeliness.
It is because he does not compete that he is without reproach.
