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.

Wind Map An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software. If the map is missing or seems slow, we recommend the latest Chrome browser. Surface wind data comes from the National Digital Forecast Database.

15 Famous Logos As we realize that we are now living in the Brand Era, where everything is branded and labelled we are more concern to companies we believe can help us, shops where we can get our supplies, or websites we trust to keep our data or information securely. This is how a company’s logo appeal as the first thing costumer will consider to trust or not. Among thousands of logos out there, some of them may look cheesy and cheap, and some visually give us confident. In order to grab our attention and get our trust, many companies even consider to re-brand/redesign their logo. As might be expected, the company will have to take the risk and be prepared of the pros and cons of this act. They should have really consider the reasons behind the redesign of their brand. Below is a list, in no particular order of what I think to be famous and successful logo redesign from their old logo to the latest with explanations of what has been improved. 1.

Live Green - Historic Cookbooks Shed Light On Sustainable Past As we study the ways past generations lived, farmed and ate, one thing is for sure... American has been blessed with clever and thoughtful cooks. And many beautiful, wonderful, educational cookbooks, too. Where would we be without the cookbook? But there is also much to be learned from studying the food prejudices and opinions of the past. Feeding America: The Historic American Cookbook Project is a marvelous treasure trove of practical information, interesting recipes and an enlightening look at how America’s attitude toward food and agriculture has changed - and stayed the same - over the last 234 years. The project, which is a collection of cookbooks and antique cooking implements from the 18th,19th and early 20th centuries is a somewhat romantic look back at a time when typical cooking methods were simpler and more sustainable than today. The cookbooks date back as far as 1798, and include descriptions and measurements that today’s reader probably wouldn’t even recognize.
Ten things you don't know about black holes Well, they’re black, and they’re like bottomless holes. What would you call them? -Me, when a friend asked me why they’re named what they are Ah, black holes. The ultimate shiver-inducer of the cosmos, out-jawing sharks, out-ooking spiders, out-scaring… um, something scary. But we’re fascinated by ‘em, have no doubt — even if we don’t understand a whole lot about them. But then, that’s why I’m here. So below I present ten facts about black holes — the third in my series of Ten Things You Don’t Know (the first was on the Milky Way; the second about the Earth). 1) It’s not their mass, it’s their size that makes them so strong. OK, first, a really quick primer on black holes. The most common way for a black hole to form is in the core of a massive star. As the core collapses, its gravity increases. The region around the black hole itself where the escape velocity equals the speed of light is called the event horizon. OK, so now you know what one is, and how they form. So there you go. Hmmm.

The Business of War 3 The Dillon Aero M134D Gatling Gun, a “six-barreled, electrically driven machine gun chambered in 7.62mm NATO that fires at a fixed rate of 3,000 shots per minute.” It was one of countless killing machines featured at SOFEX. Photo courtesy of Dillon Aero. “You know, it’s weird, man. It’s like everybody’s real cordial with each other. But, at the end of the day, we’re, like, buying weapons to destroy each other. On arriving at SOFEX, I was reminded of when I was a punk kid and it was fashionable to say things like, “The military-industrial complex is taking over the world.” SOFEX takes place every two years in Amman, and is largely the brainchild of Jordan’s king, Abdullah II, who has a penchant for special operations and massive displays of artillery. The Ultimate Warrior Competition is sponsored by KASOTC, a “counterterrorism training facility” in Jordan founded by King Abdullah. Every SOFEX commences with a “show of force” arranged by King Abdullah. Oh yeah, right. Lt.
