Study Finds Random Electrical Current May Help Folks Learn Math Mathemati-phobes rejoice. You may one day swap coffee and cramming for a trusty set of head-mounted electrodes. According to a team of researchers, hailing from the UK and Austria, non-invasive electrical brain stimulation may improve math learning. However, the results, while intriguing, require a few requisite grains of salt: The trial was small, and as yet, there is no proven physiological explanation. The technique, called transcranial random noise stimulation (TRNS), sends weak electrical impulses racing between electrodes attached to the forehead. Scientists Make Headway Toward Invisibility Cloaking The world of science fiction is rife with examples of invisibility - whether it is Harry Potter’s cloak, Romulan cloaks integrated into a spaceship’s shields, or the One Ring that helped our favorite hobbits steer clear of orcs. Of course, actually creating a device that is capable of bending light so an object appears to be invisible to the eye is a fairly tall order. However, a group of materials scientists led by Debashis Chandra at the University of Central Florida have made significant strides forward to making this long-fabled device a reality. By using nanotransfer printing, the team achieved optical properties across a large swath of material that have never been accomplished on such a large scale before, breaking barriers toward the development of a cloak that could make an object appear to be invisible.

The program’s stringent application process weeds out all but the most promising applicants before any commitment is made. Arduino Isn’t Just For Hackers ← Paul M Furley Arduino turned out to be the perfect match for JF Machines Ltd, a manufacturer of industrial digital printing machines. The open source platform offered them supply security, enormous flexibility and simple PC interfacing, all at an incredible price. Back in 2009 I worked in JF Machines Ltd – the family firm – producing the user operator software for their new digital printing machine, the PicoColour (if you’re imaging a desktop printer, try 1.5 tonnes of precision-engineered printing press…) Picocolour digital inkjet printing machine Like many high-tech manufacturers, JF Machines has historically used both in-house electronics and programmable logic controllers (PLCs).
Getting Started with Three.js ## Introduction I have used Three.js for some of my experiments, and it does a really great job of abstracting away the headaches of getting going with 3D in the browser. With it you can create cameras, objects, lights, materials and more, and you have a choice of renderer, which means you can decide if you want your scene to be drawn using HTML 5’s canvas, WebGL or SVG. And since it’s open source you could even get involved with the project. But right now I’ll focus on what I’ve learned by playing with it as an engine, and talk you through some of the basics. Cops In Dubai Are Using Google Glass To Catch Speeding Drivers Ayuda Web A police officer wearing Google Glass If you think traffic light cameras and discreet roadside cops are irritating enough, authorities may upgrade to Google Glass for catching speeding drivers soon enough. Police in Dubai have begun using Google's wearable display in an effort to capture traffic violators, according to a report by Gulf News spotted by The Verge. The technology is currently being tested by the Dubai Police Smart Services Department using two applications for tracking road-bound crimes.
80/20 Extrusion Goes Main Stream We had to do a double take when we saw this kickstarter campaign video – and we bet you will too. It seem as if some company called [Infento Rides] took generic 80/20 aluminum extrusions and built a viable commercial product out of it – that’s not something you see everyday. 80/20 is meant to be something that engineers use to build things like test rigs and manufacturing fixtures. It’s not exactly an item designed for the consumer or end user.
What every computer science major should know Portfolio versus resume Having emerged from engineering and mathematics, computer science programs take a resume-based approach to hiring off their graduates. A resume says nothing of a programmer's ability. Every computer science major should build a portfolio. A portfolio could be as simple as a personal blog, with a post for each project or accomplishment.

Ray Kurzweil’s Mind-Boggling Predictions for the Next 25 Years In my new book BOLD, one of the interviews that I’m most excited about is with my good friend Ray Kurzweil. Bill Gates calls Ray, “the best person I know at predicting the future of artificial intelligence.” Ray is also amazing at predicting a lot more beyond just AI. This post looks at his very incredible predictions for the next 20+ years.
