Rafael Lozano-Hemmer Paints With Sound
By KELLY CROW For nearly two decades, artist Rafael Lozano-Hemmer has planted motion detectors, searchlights and surveillance equipment in public plazas and parks around the world. Each time, he invites the public to activate his gadgetry with their shadows, heartbeats or some other form of interaction.Colors (Mixing color or paint: R/G/B)
The following is a message I received in my email box: john welch : > Hi. I just tried out your color mixing applet. I changed the three ovals to these values: > 100,100,55 > 100,55,100 > 55,100,100 > > I wanted to show students that you didn't have to add 3 monochromatic sources to get white. > But it looks like the applet is averaging the values rather than adding them, so that in the center of these three ovals I get 119, 119,199, where I would expect 255,255,255. > I know you don't want to go over 255, but could you do something like max(a+b+c, 255) ?

The Secret Life of Plants
It means even on the lower levels of life, there is a profound consciousness or awareness that bonds all things together. Published in 1973, The Secret Life of Plants was written by Peter Tompkins and Christopher Bird. It is described as “A fascinating account of the physical, emotional, and spiritual relations between plants and man.” Essentially, the subject of the book is the idea that plants may be sentient, despite their lack of a nervous system and a brain. This sentience is observed primarily through changes in the plant’s conductivity, as through a polygraph, as pioneered by Cleve Backster.

What the Bleep Do We Know!?™ & What the Bleep!? - Down the Rabbit Hole
How does one find focus and yet allow the flow to continue? The other question is, what is time and how does our experience of time manifest itself? Is there a fluidity of time with an ebb and flow; or is time a constant? Matter exists in a time space continuum.

Discovery Researchers Control Collective Spin States Electrically at Room Temperature Breakthrough paves way to store and process information in novel spin-electronics August 16, 2010 Processing large amounts of information in today's electronics requires large amounts of power, which results in heating. Heat can ruin modern electronics by potentially damaging the stuff that makes them work--the ever smaller and denser structures in a computer's "brain," the microprocessor that incorporates all of its logic functions. So, researchers have been investigating something called "spintronics," a field of research that uses the spin state of electrons to pave the way for a future generation of advanced, fast, low-power, heat-limiting devices that perform memory and logic functions beyond today's microprocessors.

Terraforming
Transplanting seas to inland ocean lakes? A good idea for the Middle East? The two century-old and highly respected Japanese engineering giant Shimizu has hatched a wild and crazy proposal to rehabilitate the desert for human use. Their idea is to move vast amounts of seawater along canals that would track deep into desert landmasses to create a series of connected huge inland seas measuring 30 km (18 miles) across.
Interactive Biology Serendip sees the web as a tool which can make education a more interactive and exploratory process, by making freely available educational resources at a variety of levels and also, even more importantly, be making it increasingly possible to learn by doing (see Serendip's web principles and credo on education and technology ).

Discovery Even in the Desert, Plants Feel the Heat of Global Warming NSF-supported researchers study the germination of plants in the Sonoran Desert to determine the impact of the later arrival of winter rains April 23, 2010 Global warming is a hot topic, and it's causing concern for scientists studying winter annuals in the Sonoran Desert. While desert winters have become warmer and drier over the years, climate changes have pushed the arrival of winter rains to later in the year, forcing winter annual plants like the curvenut combseed ( Pectocarya recurvata ) to emerge later when temperatures are colder.

Environmental Visualization Laboratory - Pacific Ocean Floor Affects Tsunami Propagation
As tsunami waves travel across ocean basins they are only centimeters high, but extend down to the ocean floor (unlike traditional waves which are only surface features). As the tsunami waves approaches the coast, the shallowing ocean floor pushes the water mass upwards. The quicker the ocean floor transitions from deep to shallow, the greater potential for a higher wave height. The epicenter of the earthquake that triggered the recent Japanese tsunami was very close to shore, though, which reduced the amount of the water column that is displaced and the overall tsunami height.éducation à l'environnement et au dév durable
Discovery Scientists Listen to Song of the Sun The sun is a very noisy place, generating an inferred multi-frequency song comparable to cathedral bells September 28, 2010 To most of us, the sun seems to dangle in space silently without making so much as a peep. Nevertheless, "the sun is a very noisy place," said Scott McIntosh of the National Science Foundation (NSF)-supported National Center for Atmospheric Research . What does the sun sound like?
