Isaac Asimov’s 1964 Predictions About 2014 Are Frighteningly Accurate In 1964, famed science fiction writer Isaac Asimov ventured a guess at what you might find if you set foot inside the 2014 World’s Fair. Using his gift for envisioning future technology, Asimov’s predictions from 50 years out are both stunningly accurate and perhaps a little bit depressing. Here’s a look at what he got right. Working out the Left-right-left combination to a lock Conventionally, a combination lock is opened by turning the dial two turns to the right, then to the first number, one turn left, and left to the second number, and then right again to the last number. This series of turns causes the rotors of the locks to have their notches aligned with each other (see wooden combination lock model) However, there's nothing that prevents you from starting the combination counterclockwise instead of clockwise, and conventional combination locks can indeed be opened this way. Because the tabs on the rotors have non-zero thickness, slightly less than a full turn is needed to catch subsequent rotors. On account of this, to open a combination lock by turning left right left instead of right left right, the first number needs to be several numbers further to the right, and the second number needs to be several to the left. The table below shows several locks that I worked out the left-right-left combination for.
Free Software Sentry – watching and reporting maneuvers of those threatened by software freedom Microsoft Has Failed in the Area of Hardware Microsoft — unlike Nokia — cannot fall/revert back to the tyres business Summary: Xbox One is a failed product and “Surface” is losing hundreds of millions of dollars THE LATEST episode of TechBytes covers the good news that “Microsoft May Halt Xbox One Production”; it’s news that reminds us of an important fact: “We know that the company has shipped 5 million consoles to retailers since launch, but Microsoft hasn’t been as forthcoming with actual end user sales data.” When Microsoft does not divulge these figures it always means that Microsoft has something to hide. The same thing has historically been true when it comes to Windows (number of licences issued) and other Microsoft hardware.
Have scientists accidentally created a lightsaber? New form of matter discovered that has only ever been seen in science-fiction Molecule behaves like lightsaber by moving photons around in a solid mass Discovery made after light particles were blasted through rubidium atomsThe finding could help drive the development of quantum computing May lead to creation of 3D structures, such as crystals, wholly out of light By Ellie Zolfagharifard Published: 13:47 GMT, 26 September 2013 | Updated: 15:11 GMT, 26 September 2013 Scientists have accidentally discovered a completely new form of matter that works in the same way as the lightsabers used in Star Wars. A team of physicists were messing around with photons when they managed to get the particles to stick together and form a molecule.
Kill Your Darlings There is nothing like the moment when you suddenly come upon the answer to a design problem. Whether it is a particular interaction or the perfect design element, it is a moment of pure elation. However, in that moment, there is a always a risk of an emotional attachment being formed. Essentially, we have the potential to surrender our ability to see beyond the “perfect solution” we have just created. Arthur Quiller-Couch, a British journalist, critic, and novelist once said,"Murder your darlings."
Atomic Rockets Your imagination has been captured by the roaring rockets from Heinlein's SPACE CADET or the Polaris from TOM CORBETT, SPACE CADET. But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers? Light stopped completely for a minute inside a crystal: The basis of quantum memory Scientists at the University of Darmstadt in Germany have stopped light for one minute. For one whole minute, light, which is usually the fastest thing in the known universe and travels at 300 million meters per second, was stopped dead still inside a crystal. This effectively creates light memory, where the image being carried by the light is stored in crystals. Beyond being utterly cool, this breakthrough could lead to the creation of long-range quantum networks — and perhaps, tantalizingly, this research might also give us some clues on accelerating light beyond the universal speed limit. Back in 1999, scientists slowed light down to just 17 meters per second, and then two years later the same research group stopped light entirely — but only for a few fractions of a second.
Pythagorean cup Cross section Cross section of a Pythagorean cup. A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If he fills the cup only to that level, the imbiber may enjoy a drink in peace. If he exhibits gluttony, however, the cup spills its entire contents out of the bottom (onto the lap of the immodest drinker).
A chimp-pig hybrid origin for humans? (Phys.org) —These days, getting a Ph.D. is probably the last thing you want to do if you are out to revolutionize the world. If, however, what you propose is an idea, rather than a technology, it can still be a valuable asset to have. Dr. Heron's fountain Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron, also known as Hero of Alexandria. Heron studied the pressure of air and steam, described the first steam engine, and built toys that would spurt water, one of them known as Heron's fountain. Various versions of Heron's fountain are used today in physics classes as a demonstration of principles of hydraulics and pneumatics.
Robert Lanza » The Biocentric Universe Theory: Life Creates Time, Space, and the Cosmos Itself Stem-cell guru Robert Lanza presents a radical new view of the universe and everything in it. NASA/ESA/A. Schaller (for STScI) The farther we peer into space, the more we realize that the nature of the universe cannot be understood fully by inspecting spiral galaxies or watching distant supernovas. It lies deeper.
First-ever human head transplant is now possible, says neuroscientist Promotional posters for the new Everest movie recently appeared in New York City subway stations, and these days I travel to and from work with a strange lump in my throat. Everest, which opens in wide release in the US today (Sept. 25), is based on the true story of how eight people died in a storm on the world’s tallest mountain in 1996. It’s the same story that Jon Krakauer told in his bestselling book Into Thin Air. It was, until last year, the most deadly accident in Mount Everest’s history. Then on April 18, 2014, an ice release killed 16 climbers on the mountain. Why Physicists Are Saying Consciousness Is A State Of Matter, Like a Solid, A Liquid Or A Gas — The Physics arXiv Blog There’s a quiet revolution underway in theoretical physics. For as long as the discipline has existed, physicists have been reluctant to discuss consciousness, considering it a topic for quacks and charlatans. Indeed, the mere mention of the ‘c’ word could ruin careers. That’s finally beginning to change thanks to a fundamentally new way of thinking about consciousness that is spreading like wildfire through the theoretical physics community.
