Controlling the speed limit of smart technology gadgets

EXCERPT: Understanding why there is a speed limit on how fast the properties of light can be changed is the way forward for the next generation of consumer electronics including smart watches, screens and glasses, according to new research. According to researchers from Chalmers University of Technology speed limits apply to the control of light and this affects the efficiency of optical switches used for Internet traffic and device communications. Working out why it is not possible to increase the speed beyond a certain limit has led to new alternatives, such has how to control the path of light to take a different route. Figuring this out promises faster and more powerful electronic devices, as well as being key to the next wave of smart technologies. The reason why this matters is because light and other electromagnetic waves are necessary for all modern electronics, like a smartphone. To seek improvements in smart technology physicists have constructed speciality materials called optomechanical metamaterials. Te properties with these materials address limitations with natural materials, enabling scientists to control the properties of light with relatively high degrees of precision....

Physics-defying space engine flunks out

EXCERPT: The "impossible" EmDrive may be just that, though don't count it out just yet. A group of German physicists at TU Dresden has tested two proposed means of propellantless propulsion – the EmDrive and Mach Effect Thrusters – and found the act of testing is what makes these arguably physics-flouting technologies appear to work. The researchers – Martin Tajmar, Matthias Kößling, Marcel Weikert and Maxime Monette – presented their findings last week at the Aeronautics and Astronautics Association of France’s Space Propulsion conference. The title of their paper is "The SpaceDrive Project – First Results on EmDrive and Mach-Effect Thrusters."
