(Phys.org) —John Howell, a Professor of Physics at the University of Rochester, and his teenage son, have uploaded a paper to the preprint server arXiv in which they suggest that some common magicians' tricks could be used ...
Free-space optical communication, the communication between two devices at a distance using light to carry information, is a highly promising system for achieving high-speed communication. This system of communication is ...
