The Nature of Light and Color in the Open Air
"Moreover, this book is written for all those who love Nature; for the young people going out into the wide world and gathering together round the camp-fire; for the painter who admires but does not understand the light and colour of the landscape; for those living in the country; for all who delight in travelling; and also for town-dwellers, for whom, even in the noise and clamour of our dark streets, the manifestations of Nature remain." - Marcel Minnaert [more inside]

*relativity by Drzach & Suchy.
"Our work explores the relativity of perception and the dependence of appearance on the surroundings. It illustrates the fact that the message communicated to the observer can dramatically change with varying external conditions. Multiple images are encoded within a single physical object — a white panel, which displays the separate images under appropriate lighting conditions. The underlying principle of our technique is based on a simple observation: the shadow cast by an object depends not only on the object itself, but also on the light; therefore the same object under changing lighting conditions can totally change its appearance

Light makes a comeback.
“New technologies — more sophisticated imaging techniques, fluorescent molecules that act as beacons of light in the cell, and the computing power to gather and stitch together multiple images and create videos from high-powered microscopes — make it possible to harness one of light’s key advantages: gentleness. Unlike higher-resolution techniques, light microscopes can image biological structures without killing them or chemically fixing them. At Harvard, the resurgence of light microscopy is making it possible to see structures and events that have never before been seen in the context of living cells and organisms.” Also don't miss the video samples
of “in vivo” imagining.

Apparently, the new black is... really, really black. "Researchers in New York reported this month that they have created a paper-thin material that absorbs 99.955 percent of the light that hits it, making it by far the darkest substance ever made -- about 30 times as dark as the government's current standard for blackest black."
But what possible benefit to society could come from this blacker than black substance? Why, invisibility cloaks
, of course! [more inside]

John Lennon’s lighthouse. He said, ‘Well, actually, I invited you because I wanted to know if you can build the lighthouse in my garden,’ and I said: ‘Oh, dear, no, no. It’s just a conceptual idea. I don’t know how to build anything.’
makes a dream of John's come true in Iceland. It’s geothermal
. Amy Goodman's take
on the subject. And, of course, video

"The trick to education is to teach people in such a way that they don't realize they're learning until it's too late."
Fluorescein-dyed water appears suspended in midair, only to "flow" upwards moments later. The careful dance of a splashing drop is frozen and taken for granted, painstakingly analyzed in a brilliant defiance of how water should behave. Such is the wonder of what modder Nate True calls his Time Fountain
(YouTube embedded & worth it)—a well-documented, DIY version of classic science center favorite, the Water Piddler

is lined with photos created using the same technology, pioneered by Harold Eugene Edgerton

Little visual miracles.
For more than forty years that most American of photographers, Chevalier in the Order of Arts and Letters Lee Friedlander
, has recorded modern American
urban life -- with its jumble
, and cars
, and television sets
. He likes to turn a common blunder of amateurs
-- photographing something nearby with one's back to the sun
-- into a leitmotif
. His shadow plays the role of alter ego
, sticking to the back of a woman's fur collar, clinging to a lamppost as a parade of drum majorettes passes by, reclining like a stuffed doll on a chair. Clever jigsaw puzzles, his pictures frequently reveal themselves to be laconic, austere poems
to what Friedlander
has termed "the American social landscape
',' meaning mostly ordinary places and affairs. "Friedlander," an exhibition of more than 480 photographs and 25 books
covering decades of work, runs at MoMA through Aug. 29, before traveling to Europe until 2007. More inside.

, Roden Crater I've always wanted to make light something that you treasure. Not just light reflected in glass, or in a scrim, or on the surface of some object. But light objectified. We generally use it to illuminate other things. But I wanted to force people to pay attention to the thingness and revelation of light. This is a place that will do that.James Turrell

High Tec Shadow Play
'In Rotterdam, Canadian artist Rafael Lozano-Hemmer used two 7000 watt lamps to create 1200 square metres of projected images which were overlayed by the shadows of passer-by's. A computer based tracking system monitored the shadows. Once the shadows matched the projected image, a new image (or "scene") was triggered. ' An impressive (if extravagant) bit of public art (QuickTime)

glowing wires, cool to the touch. uses very little power, and usable for...anything you need to light. really beautiful light sculptures waiting to be created.

THAT'S a speeding ticket...
Scientists push light up to 300 times the SPEED OF LIGHT.
I just got a floaty-glowy feeling. Some interesting interesting stuff is happening in our world.
My favorite quote from the article: "That is so fast that, under these peculiar circumstances, the main part of the pulse exits the far side of the chamber even before it enters at the near side. "

I'm a gadget freak and I've got lights in my house controlled by my computer
. But the folks at misterhouse.net
have taken it 10 steps further. There's a web interface to all sorts of things, inlcluding the lighting system, the vcr, and reminders of new mail. That's some pretty nifty geek stuff they have going on there.
