Rafael Lozano-Hemmer Paints With Sound - WSJ.com
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.

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) ?
ExploreScience has excellent, simple, informative, interactive Shockwave experiments: sound beats, Doppler, interference, etc., prism, ray tracing. Optics. These are very nice, even if you don't read Italian. Can adjust strength of colors.

The Secret Life of Plants | Watch Free Documentary Online
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.
National Science Foundation (NSF) Discoveries - Researchers Control Collective Spin States Electrically at Room Temperature - US National Science Foundation (NSF)
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. The challenge: controlling electron spins with low power at room temperature instead of temperatures approaching absolute zero (-273 degrees Celsius) so their resulting technologies can carry out tasks in normal-use environments.
National Science Foundation (NSF) Discoveries - Mystery Behind Weak Earthquake Faults Solved - US National Science Foundation (NSF)
A chance meeting and a common interest in tectonic faults took Cristiano Collettini and Chris Marone to the Isle of Elba to sample a tectonic fault that breaks most of the rules of fault mechanics. Their work reveals why these faults slip. In May 2008, Cristiano and I were at a workshop in the Italian Apennines to discuss a possible drilling project into the low-angle, normal faults (ones that occur when the Earth's crust is stretched) in that region.World temperatures

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 ).
