New Installation Traps Visitors in Prison of Light by Nonotak Studio
Method Treats Heat Like Light
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
The approach relies on engineered materials consisting of nanostructured semiconductor alloy crystals. Heat is a vibration of matter — technically, a vibration of the atomic lattice of a material — just as sound is. Such vibrations can also be thought of as a stream of phonons — a kind of “virtual particle” that is analogous to the photons that carry light. The new approach is similar to recently developed photonic crystals that can control the passage of light, and phononic crystals that can do the same for sound.

Shedding Light On Anderson Localization |
Waves do not spread in a disordered medium if there is less than one wavelength between two defects. Physicists from the universities of Zurich and Constance have now proved Nobel Prize winner Philip W. Anderson’s theory directly for the first time using the diffusion of light in a cloudy medium.
Light cannot spread in a straight line in a cloudy medium like milk because the many droplets of fat divert the light as defects. If the disorder — the concentration of defects — exceeds a certain level, the waves are no longer able to spread in a cloudy medium at all. Philip. W. Anderson was the first to describe this transition to a localized wave in 1958, which is why it is also referred to as Anderson localization. Until now, however, Anderson localization had never been observed. For the first time, physicists from the universities of Zurich and Constance have now demonstrated the Anderson localization of light directly in an experiment. As their article published in the science journal Nature Photonics reveals, the Anderson localization of light only occurs in much cloudier media than milk — in other words, only if there is only about one wavelength between two defects.
Light propagation followed closely to a billionth of a second
For their study, the team examined the diffusion of light in a very strongly scattering medium. “In order to make the diffusion of the light and thus Anderson localization visible, pictures had to be taken at an interval of less than a billionth of a second,” says Christof Aegerter, explaining the technical challenges of the project. Based on these high-resolution images, the researchers were able to show that in the case of Anderson localization light is no longer able to spread any further in the medium after around four billionths of a second (or nanoseconds).
Until now, it was very difficult to calculate certain characteristics of localized states, such as how large the critical concentration of the defects is. “Thanks to our experimental data, the theory will gain new impetus and be able to be refined further,” Aegerter is convinced.
The Anderson localization of waves is a general phenomenon that occurs in all waves with a heavy scattering and is also of practical importance: It describes, among other things, the transition between a conductor and an isolator.
Abstract X-Ray Art by Wonman Kim / Curt Man
They say you are what you eat, which definitely makes me a walking sentient pizza, but X-Ray technology has come so far in the capable hands of Wonman Kim that now we can actually see that we’re made up of a bunch of disparate, incongruous parts and inanimate objects. Though that wont stop me from telling people I’m a pizza.
Applying Sunblock - Visible vs Ultraviolet Light
Seeing how the lotion has different visual properties in different light - via Life Pixel
Sunblock being applied to face in visible light & ultraviolet UV light. As you can see this sunblock absorbs UV light rays and therefore appears to be black in the UV only video. In visible light it looks like ordinary lotion.
You can see the video version at Life Pixel here (scroll down to video)
About the installation:
This concept was born of Chi-yung’s experience working with light over the past 10 years: learning, applying and creating lighting while living in Hong Kong, Finland and France.
Wong explores the ideas of the Big Bang, the parallel universe, and the influences of the enlightenment period into his own personal imaginarium that creates a mysterious alternative reality. Psychological turmoil and ecstasy are no longer shut away, but becomes physically manifest in the environment around you. These pieces use light, angles and different shades to create horror and beauty. As you explore the installation, what is your personal experience of it? Does the trick of the light make you feel uneasy? Perhaps you see beauty in being liberated from your senses.
Music composers Pierre Faa, Steve Hui, Martin Lai @ Mariscal Label and Tôn-Thất An were invited to compose the music specially for the scenographic installation exhibition.
2011 audio / visual installation by Rafael Lozano-Hemmer stores 288 samples from public, replayed as a stack with blinking lights:
As a participant speaks into an intercom, their voice is automatically translated into flashes of light and then this unique blinking pattern is stored as a loop in the first light of the array. Each new recording pushes all previous recordings one position down and gradually one can hear the cumulative sound of the 288 previous recordings. The voice that was pushed out of the array can then be heard by itself.
Electri-flowers by Robert Buelteman
Nothing worth doing was ever easy, and Robert’s complex method of capturing these images has been honed over a 10 year span, with an average of 60 hours per week to produce just 80 images. Starting by placing a plant on a metal board, Rob then passes an electrical current through it, getting its juice from a simple car battery. He then takes a fiber optic cable and runs it over the surface, capturing the invisible radiation emitted from the electrical charge, and burning the sliver of light onto film. And I’m pretty sure this is how super-powered mutated plants that one day enslave the human race are created. So thanks for that, Rob.
3D Design More Than Doubles Solar Power
Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.
Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in 3D configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Human Sculpture | UvMotion
Two projects by Jafta Hoekendijk exploring the body in motion with photography in different ways.
More background on the technique used in Human Sculpture can be seen in a video here.
The artist also has a Tumblr blog.
Lantern and Ice Festival
The Lantern Festival also known as the Yuanxiao Festival or Shangyuan Festival in China, features many luminous ice sculptures meant to replicate traditional chinese architecture. This festival marks the Lunar New Year in Beijing and I kind of want to be inside some of these.
