Magenta Ain't A Colour

Magenta Ain't A Colour
A beam of white light is made up of all the colours in the spectrum. The range extends from red through to violet, with orange, yellow, green and blue in between. But there is one colour that is notable by its absence. You should have seen a green afterimage, but why is this significant? The afterimage always shows the colour that is complementary to the colour of the image. It is a common misconception that red is complementary to green. All the colours in the light spectrum have complements that exist within the spectrum – except green. The light spectrum consists of a range of wavelengths of electromagnetic radiation. When our eyes see colours, they are actually detecting the different wavelengths of the light hitting the retina. If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina.

The Cyber Sea: World's Largest Internet Undersea Science Station Boots Up [Slide Show] Thanks to a new, wired undersea observatory, when it comes to exploring the deep blue sea, there will be no more of this tethered buoy business or taking ships out to upload data from brief time snapshots taken by instruments. The NEPTUNE network set to go online Tuesday will stream data from hundreds of undersea instruments and sensors direct from the Pacific Ocean floor to the Internet 24/7, year-round. The network is expected to produce 50 terabytes of data annually, all of which will inform scientists about everything from earthquake dynamics to the effects of climate change on the water column, and from deep-sea ecosystems to salmon migration. "It's revolutionary in that it brings two new components into the ocean environment, which are power and high-bandwidth Internet," says Project Director Chris Barnes, from the project's offices at the University of Victoria in British Columbia. NEPTUNE will also study the extensive gas hydrate deposits that lie along the continental margin.

Disposable Cameras There are lots of disposable camera Instructables on the site. It was hard to choose, but I've included some great ones! Need a taser, a coil gun, a flash grenade? From simple everyday parts you can make this glove which has two modes. Learn how to make a simple but extremely effective Coil gun using only a "few" parts that are fairly easy to obtain by only going to a few places and possibly online. I've come up with a project that i've been contemplating for a long time. Are you tired of having your Ni-Cad batteries that refused to charge and simply die? Well... Caution I'm not liable if your shock yourself and injury or kill your self, working with high voltages can be dangerous!! Before I get too far in this instructable, I would like to say that this was not my original idea. First off, i know conrad2468 made a similar one(hint hint "similar"). Make a simple triggerable strobe for taking action photos with.

6 Scientific Discoveries That Laugh in the Face of Physics As we've pointed out before, there are some startlingly simple questions that science can't answer. And then there are the special occasions where the universe up and does a freaking magic trick that seems to be designed by an unjust, all-powerful entity dedicated to making scientists slowly pull off their glasses while saying, "What in the hell?" For instance ... #6. We intuitively understand the direction that energy travels -- from the thing with energy to the thing with less energy. GettyThat asshole always has to be the center of attention. There's a discrepancy between what science says should happen and what the sun actually does, and it's known as the sun's coronal heating problem. The facts are pretty straightforward; the sun's surface sits comfortably at a blazing temperature of roughly 5,500 degrees Celsius. GettyHe's a loose cannon! The heat source (the giant ball of nuclear explosions and plasma) should be the hottest thing, not the empty vacuum of space around it. #5. #4.

Complete relationship chart between psychological (&quot;personality&quot;) types Complete relationship chart between psychological ("personality") types Chart #1 Key to the chart: Usage: Type A x Type B -> Intertype Relationship. Example #1: A = 'ENFp ', B = 'INFp ', Cross-reference result = 'Cnt'.Conclusion: Between ENFp and INFp there is Contrary Intertype Relationship. Example #2: A = 'ISTj ', B = 'ENTp ', Cross-reference result = 'Sp<'.Conclusion: Between ISTj and ENTp there is Intertype Relationship of Supervision, where ISTj is Supervisee to ENTp. Chart #2 Usage: Your [A] is [Intertype Relationship] to your [B]. Example #1: A = 'Qid', B = 'Act', Cross-reference result = 'Ego'.Conclusion: Your Quasi-identical is Super-Ego to your Activity Example #2: A = 'Bn<', B = 'Ego', Cross-reference result = 'Bn>'.Conclusion: Your Beneficiary is Benefactor to your Super-Ego.

Einstein once said, “If you can’t explain it simply, you don’t understand it well enough.” The Open University, an online educational institute, took this seriously. It came up with “60-Second Adventures in Thought.” Believe it or not, questions of infinity, defining a twin paradox, and other mind-bogglers, are succinctly and clearly explained in one minute for each idea. 1. 2. 3. 4. 5. 6. By Ingrid Longauerová, Epoch Times SOURCE Frequent Halos Halos appear in our skies far more often than do rainbows. They can be seen on average twice a week in Europe and parts of the United States. The 22° radius circular halo and sundogs (parhelia) are the most frequent. In this HaloSim3 simulation the sun is surrounded by a 22° halo and flanked by sundogs.

Paul Nicklen’s “Polar Obsession” (9 Photos All Photographs © Paul Nicklen / National Geographic A young polar bear leaps between ice floes. Barents Sea, Svalbard, Norway. A kittiwake soars in front of a large iceberg. In the Arctic spring, meltwater channels drain toward and down a seal hole, returning to the sea. Narwhals dive deep under the ice to feed on Arctic cod, then return to the surface to breathe and raise their tusks high in the air. A gentoo penguin chick peeks, checking for patrolling leopard seals before tempting fate. A leopard seal feeds Paul Nicklen a penguin. A large bull walrus returns to the shores of Prins Karl Forland after diving and feeding on clams. Mother bear and two-year-old cub drift on glacier ice. Looking towards an uncertain future, a huge male bear triggers a camera trap, taking his own picture. For more from Nicklen on Polar Obsession, see our interview with the photographer.
