The thought of creating a Toy Big Bang is a little disturbing but not to this man. Igor Smolyaninov at the University of Maryland, College Park, has creating a tiny Big Bang in his lab using meta materials. Metamaterials are periodic structures that can be engineered to steer light in specific ways. The trick is to manipulate the properties of the "electromagnetic space" in which light travels by controlling the values of the permittivity and permeability of this space.
In recent years, physicists have had a great deal of fun using metamaterials to build all kinds of exciting devices, the best known being invisibility cloaks which steer light around an object, thereby concealing it from view.
But metamaterials have a more profound application because there is a formal analogy between the mathematics of electromagnetic spaces and the mathematics of general relativity and the spacetime it describes. That means it is possible to reproduce inside a metamaterial an exact copy of many of the features of spacetime. We've looked at a number of these ideas, such as how to build a black hole and even create a multiverse.
This system also gives an interesting insight into the nature of time machines. The question Smolyaninov asks is whether it is possible to create closed time-like curves in his material. This is equivalent to asking whether it is possible for particles in a Minkowski space to travel in a curve that takes them back to the point in space-time where they started.
He considers this by imagining a cylindrical metamaterial in which the z-dimension and radial dimension are space-like and the angular distance around the cylinder is time-like. Can closed time-like curves exist in this system, he asks. "At first glance, this question is simple, and the answer should be "yes"," he says.
But under closer examination the answer turns out to be different. He points out that while it is possible for light rays to follow circular paths that return to the point from where they started, these rays would not perceive the angular dimension as time-like.
By comparison, any ray that does perceive the angular dimension as time-like cannot actually return to the same point in space-time, (although it can travel a world line that is very close to a closed time-like curve). So time machines, even trivial ones like this, are impossible.
That's hugely impressive work. Smolyaninov is one of the world's leading thinkers on metamaterials and has done much to advance the theory that links electromagnetic and Minkowski spaces.
Now he's actually getting his hands dirty. In creating for the first time metamaterials that reproduce the Big Bang and the arrows of time that result, he's surely achieved an extraordinary landmark.

Go ahead. Text while driving...because your not driving if new Google technology has anything to do with it. Sebastian Thrun who was the key man in the winning of lthe DARPA challenge for the driverless vehicle is now working hard fo Google and they have developed a driver-less vehicle that will navagate city streets, in full traffic and have been testing it for months now. Its driving record to date is perfect. It uses a variety of sensors to map the streets, moving vehicles, and pedestrians to navigate and probable 'sees' much more that we as humans even pay attention to.
Sebastian evisions a time when there is designated lanes for these self driving cars the can move faster and closer together easing traffic jams and giving the 'rider' more time to do his or her favorite things. It can get you to work or home quicker so you have more time in the day. Having an innate dislike of driving with muggles, I love the idea. Hurtling at fast speeds with humans is not a great idea to me.

The federal government is pushing the New transparent solar windo coating of a company called New Energy Technologies, Inc. They are determined to get it out of the lab and into the hands of building and home owners. Goverment researchers at the National Renewable Energy Labortory are initiating a plan to help start-ups an other companies to get emerging solar technoloties off the ground and running, create more green jobsand lover the cost of installed solar energy options.
New Energy Technologies' See-through solar coating is called SolarWindow and is designed for use on transparent glass on homes and commercial buildings. The effeciency is not as high as silicon solar panels but could be made cheaply enough to compensate for the difference, especially for commercial buildings with a lot of glass to work with. I have been watching the emerging print on/paint on solar technology awaiting some major breaththoughs in effectiantcy and utilization.

This reports to be one of the technologies that I have been waiting to see but lacks the follow-through. MIT chemist Daniel Nocera has unveiled details about his long-awaited "artificial leaf" invention, a small solar cell that mimics photosynthesis and has the potential to produce low-cost electricity for individual homes - an advance that could be particularly valuable in the developing world, where many people lack electricity.
The technology is about as small as a playing card and has the potential to be a game changer, but “Artificial Leaf” is a bit of a stretch since the cell or leaf has to be put in a gallon of water to work. Then it separates hydrogen and oxygen to be used in fuel cells. Now if they can find a way to pipe in the water like veins in a leaf and have it separate it then it might be closer. But this is far from the target but interesting none the less.

LAS VEGAS, NV -- 01/05/11 -- Vuzix Corporation (TSX-V: VZX) (OTCBB: VUZI) ("Vuzix" or the "Company") announced today that it has won an Innovation Award at the 2011 Consumer Electronics Show (CES) for its revolutionary see-through Augmented Reality (AR) eyewear. Code named "Raptyr," the glasses look and wear like a conventional pair of glasses.
this brings mobile computer or phone display technology to an amazing point of being able to overlay information on the world you view it will be interesting to see then in action.

At this point I have few complaints about my windows system as it does what I want it to do quite elegantly. Internet Explorer, though could use an upgrade. I tried the IE9 beta but it was a bit unstable on my profile. Worked on my system but not on my customized profile. That was fine, as I really do not want to put a beta on my fine turned system.
The lastest rumor is that IE 9 RC is planned to be available on January 28th. We also expect the final release on/around MIX ’11!Internet Explorer 9 promises to have first-rate HTML5 support when it eventually ships—at least for the features it will support. But HTML5 has become a label for a big set of interrelated Web authoring specifications, and Microsoft's new browser won't cover them all. Features whose specifications are currently unstable and still undergoing extensive changes won't be found in Internet Explorer 9, because Microsoft wants its browser to support only those features that have stable specifications.
Explorer is leaner and meaner=Smaller footprint on the desktop. It has been so big and clunky looking and as an artist this has always been a issue with me.
“The browser is the stage and the backdrop, but the website is the star of the show,” Microsoft general manager of Internet Explorer Dean Hachamovitch tells Wired.com. “We think the browser should totally take a back seat to the sites.”
Freeing up those extra pixels with a minimal top bar is a path others in the industry are taking. Chrome shipped with the tabs-on-top look two years ago, Mozilla has adopted it for Firefox 4, and Safari has flirted with in the past. Opera offers a few different choices for where to put your tabs.
Other notable details: a unified search and URL bar (a la Google Chrome) where you can get search suggestions as you type. Bing is the default, but you can add Google, Wikipedia or a host of other engines. There’s also an enlarged back button, (a la Firefox) and a noticeable lack of menu items in the main bar. Something else new in IE9 is the New Tab window with thumbnails of your most commonly-visited sites, which looks much like what you’ll find in Safari, Chrome and Opera. A nice addition here is a little bar in each thumbnail that shows how much time you’ve spent on each site.
The reason these same design themes (top-tabs, unified URL bar) keep showing up in all the browsers is that they just make sense from a usability standpoint. Designers use a constantly evolving visual language to suggest interactions. It’s no different than the way advertisers, filmmakers and visual artists borrow ideas from each other to trigger certain emotions and reactions in an audience.
So we can’t cry “copycat.” Plus, IE9 does offer some unique UI enhancements you won’t find elsewhere.
One is the new notification system — instead of a pop-up in the middle of the screen or at the top (“You need to install Flash!”), you see only a slim notification about as tall as your index finger slide up from the bottom of the screen.
But the coolest new innovation is the ability to “pin” a web page to your Windows taskbar.
This looks to be an interesting evolution of the browser and I an ready for it. Time to start exploring HTML5 standards to be ready when it all comes online. Look for it but I will probably wait for the final release. Hate when my system blows up!

There are some things that you just think "If this is even possible, I on not going to be here to see it". One of those things for meat least was a Start Trek favorite the Food Replicator. Farfetched, it was at best, but cool none the less.Well the people at Cornell University would like to change your mind. They are working on something close called a food printer. Who knew you could print and eat!Will the printer replace a kitchen stove in the future? It's possible that this food printer, called a “FabApp,” may do just that. Using raw-food “inks” set up in syringes, a specialized printer creates cookies, pie and other treats. Gawker reports that the food list is currently limited to ingredients that can be extracted from a syringe. Researchers have had success with chocolate, cake and cookies. But they think the machine could be developed to create customized menus for “fussy” customers — or that the world's great chefs could share their patented recipes for download.

Sometimes it is had to figure out the user of technology when it first comes out. Augmented reality has been one of those. Being able to see an animated dragon sitting on apiece of paper doesn't do much but show of the tech but it takes a moment for someone to use it in a way that makes you go ....ahh I that is what that is for. Word Lens is the app that will do this for this particular innovation. Word Lens is a smart application for the Iphone only (currently) that translates text in real time. When looking at a sign "through" the app of the phone Spanish text will be translated on the sign or wall or maybe ever clothing. Genius! It is like magic!

Slightly borg-like but really quite functional, the glasses by Vuzix are a step forward in computer display and the integration of augmented reality into our own reality! Projecting a display onto clear lenses or contacts would be the optimal configuration, but this is as close as we are getting but if could make apps likeWord Lens for the Iphone incredible to use.
If you own a Smartphone or pocket PC, then XDA-Developers if the site to go to. I've found in a wonderful resource for modifying and tweaking my own pocket PC. I first encountered it when finding answers for my sprint Mogul, and now they are wonderful resource for my sprint Touch Pro. I discovered just recently, that they have found a way to improve video quality on the HTC touch HD. The tweak should also work on the Touch Pro and the Touch Diamond.
On these phones, the Task Manager has been little memory limit with reference to the camera application. It only allows it 4 MB of memory, but this tweak changes that to 8 MB, which will require more memory to run but should not be a problem with the memory of these phones and you should wind up with a much clearer video.
Download and run the cab, it will only change one registry value: in HKEY_CURRENT_USER\Software\HTC\Taskmanager\Lite it will change "DesiredMemory" to dword: 8192 (default was 4096); soft reset your device.
