(PhysOrg.com) -- An infrared laser developed by Arizona company Raytheon Missile Systems has been demonstrated shooting down incoming drones over the ocean off the coast of California.
(PhysOrg.com) -- Anybots, a Silicon Valley start-up company, has developed a telepresence robot called QB, which is a mobile device that can represent you in your next meeting at the office if you are unable to make it, or ...
(PhysOrg.com) -- NEC and Brother are both developing wearable prototype devices that use Retinal Imaging Display (RID) technology to project images directly on the wearer's retina. NEC's gadget is designed to interpret foreign ...
In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both ...
