Engadget Daily: 'The Imitation Game,' Ricoh's upgraded 360-degree camera, and more!
Alan Turing has long been regarded as the father of modern computing. Why? We're glad you asked. Today, we dive into the history of the Turing machine, go hands-on with Ricoh's new Theta camera, and take a look at Corning's new Gorilla Glass 4. Read on for Engadget's news highlights from the last 24 hours.
Turing machine built from artificial muscles may lead to smart prosthetics
In the hierarchy of computing hardware, artificial muscle doesn't really even register: it's usually a target for action, not the perpetrator. The University of Auckland has figured out a way to let those muscles play a more active role. Its prototype Turing machine uses a set of electroactive polymer muscles to push memory elements into place and squeeze piezoresistive switches, performing virtually any calculation through flexing. The proof-of-concept computer won't give silicon circuits any threat when it's running at just 0.15Hz and takes up as much space as a mini fridge, but the hope is to dramatically speed up and shrink down future iterations to where there are advanced computers that occupy the same size as real muscles. Researchers ultimately envision smart prosthetic limbs with near-natural reflexes, completely soft robots with complex gestures and even a switch from digital to analog computing for some tasks. Although we're quite a distance away from any of those muscle-bound ideas becoming everyday realities, it's good to at least see them on the horizon.
Google's Turing doodle celebrates his genius, reminds us how dumb we are (video)
This week sees many corners of the globe celebrating the 100th anniversary of the birth of Alan Turing. A man whose contribution to the worlds of tech and gadgets is immeasurable -- a sentiment not lost on Google. Today, geeks and norms worldwide will be waking up to possibly the most complex doodle to date. Can you set the machine and spell out "Google"? If you can, you'll be sent off to lots more information about the man himself. This isn't the only thing Mountain View's done to keep his legacy alive, having previously helped Bletchley Park raise funds to purchase (and display) Turing's papers, and more recently helping curators at London's Science Museum with its Codebreaker - Alan Turing's Life and Legacy exhibition. If you haven't already, head to Google.com and pop your logic hat on, and if you get stuck, head past the break for a helpful video.
Alan Turing's breakthrough machine gets a loving Lego tribute (video)
In the world of technology, having one of your inventions rendered in Lego form is the equivalent of a musician being parodied by Weird Al -- it's a sign you've truly made it and tribute to your influence. So, we're more than a little surprised to see that it's taken this long for the Turing Machine to be lovingly built from plastic bricks. The heart of this simple logic device is a Lego Mindstorms NXT set, but the soul is in Alan Turing's genius -- a man who was before his time and unjustly persecuted for failing to properly fit into society's molds. Dutch researchers Jeroen van den Bosand and Davy Landman built the device as a tribute to Turing, who would have celebrated his 100th birthday this Saturday. If you're in Amsterdam you can see the machine yourself at Centrum Wiskunde & Informatica's Turings Erfenis exhibit. Or, you can watch the short explanatory video after the break.
Remembering Alan Turing at 100
Alan Turing would have turned 100 this week, an event that would have, no doubt, been greeted with all manner of pomp -- the centennial of a man whose mid-century concepts would set the stage for modern computing. Turing, of course, never made it that far, found dead at age 41 from cyanide poisoning, possibly self-inflicted. His story is that of a brilliant mind cut down in its prime for sad and ultimately baffling reasons, a man who accomplished so much in a short time and almost certainly would have had far more to give, if not for a society that couldn't accept him for who he was. The London-born computing pioneer's name is probably most immediately recognized in the form of the Turing Machine, the "automatic machine" he discussed in a 1936 paper and formally extrapolated over the years. The concept would help lay the foundation for future computer science, arguing that a simple machine, given enough tape (or, perhaps more appropriately in the modern sense, storage) could be used to solve complex equations. All that was needed as Turing laid it out, was a writing method, a way of manipulating what's written and a really long ream to write on. In order to increase the complexity, only the storage, not the machine, needs upgrading.
Biological computer can decode images stored in DNA chips, applications remain unclear
Scientists from the Scripps Research Institute and Technion–Israel Institute of Technology have taken biological computing one step further, with a new molecular machine capable of decoding images stored on a DNA chip. Though it's referred to as a "biological computer," the researchers' machine isn't much like a CPU at all -- unless your CPU was manufactured in a test tube filled with a smoothie of DNA molecules, enzymes and ATP. Once they found the right mix, the team proceeded to encrypt images on a DNA chip and used their Turing machine-like creation to decode them, with fluorescent stains helping to track its progress. The above image, read from left to right, gives a more literal idea of what the system can do -- basically, it takes a hidden image and extracts a given sequence. Storing data on DNA isn't anything new, but decrypting said data in this fashion apparently is. The applications for this kind of organic computing remain a bit fuzzy, but it's pretty clear that whatever follows probably won't look anything like a typical computer. The team's findings were recently published in a paper for the journal Angewandte Chemie, the abstract for which is linked below. For a slightly more readable explanation, check out the full press release after the break.
Turing machine built from wood, scrap metal and magnets, 'geek' achievement unlocked (video)
We take it for granted nowadays that thumbnail-sized silicon chips can crunch through the most complex of calculations, but early last century, mathematical tasks were still being carried out by humans. It was around that time that one Alan Turing, Enigma code breaker and general computer science pioneer, came up with what was essentially a thought experiment, a mechanical machine capable of simulating and solving algorithms just like a grown-up CPU. Well, you know where this is going by now, one British software engineer decided to build just such a device, out of old bits and bobs he had lying around his geek lair, producing a working model that was recently shown off at the Maker Faire UK in Newcastle. The only downer, as he points out, is that it'd take "months to add two numbers together," but all good things start off humbly. Video after the break.
