Are There More Than Three Dimensions? For most of our history, we've rested easy in the notion that there were three dimensions that have existed throughout time: length, width and height. Ah, the good old days. In the early 20th century, Hermann Minkowski and Albert Einstein connected our comfortable three dimensions with a fourth, time, defining special relativity using a space-time continuum. This kind of worked, but still didn't explain a troublesome new theory of gravity called quantum mechanics that arose around the same time Minkowski and Einstein were working on their theories. While higher theoretical dimensions began with Descartes in the 1600s, in the 1970s string theory expanded on this idea as physicists attempted to tie everything together in one elegant explanation of the universe.

Invisible Worlds Richard Hammond's Invisible Worlds is a BBC television documentary programme presented by Richard Hammond that features state-of-the-art camera technology used to focus on what humans cannot see with the naked eye. It is one series long consisting of three episodes. 1. Speed Limits - Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. The human eye takes about fifty milliseconds to blink. But it takes our brain around a hundred and fifty milliseconds to process what we see. What new marvels would we see? 2. From death-defying aerial repairmen in the United States using ultraviolet cameras to seek out an invisible force that lurks unseen on power lines, to German scientists unlocking the secrets of animal locomotion with the world's most powerful moving x-ray camera, to infrared cameras that can finally reveal the secrets within a humble beehive, he shows how new technologies are letting us see our world anew. 3.
10 Amazing Augmented Reality iPhone Apps While Lawnmower Man may have led us to believe the future was a virtual one, it seems that in fact augmented reality (the overlaying of digital data on the real world) is where we're headed. A buzz technology right now, augmented reality apps are quickly gaining momentum on the iPhone. So to add to the quick overview of six AR apps we brought you earlier, we sort the digital wheat from the pixellated chaff to bring you ten AR apps for the iPhone that vary from functional, to educational, to just plain fun. 1. Although the wisdom of getting drunk people to wave their iPhones around on today's mean streets is questionable, if you drink responsibly, as this Stella Artois-backed app urges you to, this could be a handy tool. 2. Another corporate-backed app, this time by Plantronics, is WorkSnug, an iPhone app that finds digital nomads a place to lay their weary laptop. 3. This star map app will spell out the stars, planets and constellations for you. 4. 5. 6. 7. 8. 9. 10. iPew

Google: Behind the Screen What if all the information in the world was categorized and easily searchable? What if all the news from around the world, all books, written texts, photos and videos that exist on a place in the world would be collected, and would be available everywhere?

Tegenlicht visits the head office of Google in Mountain View, California and spoke with Vint Cerf, who commissioned by the American army is the forerunner of the developed Internet. Google grows like a cabbage and they continue to hire more and more smart people in order to achieve their company goal faster. But in China to cooperate in censorship, Google have lost a lot of confidence. Watch the full documentary now

The Search for Life: The Drake Equation For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that. Dr Frank Drake was one of the leading lights in the new science of radio astronomy when he did something that was not only revolutionary, but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their new 25-meter radio telescopes at a star called Tau Ceti twelve light years from earth, hoping for signs of extra-terrestrial intelligence. Although project Ozma resulted in silence, it did result in one of the most seminal equations in the history of science - the Drake Equation - which examined seven key elements necessary for ET intelligence to exist, from the formation of stars to the likely length a given intelligent civilization may survive. However, in the 50 years of listening that has followed, not one single bleep has been heard from ET.
