Cavendish Professor of Physics However, it was poorly advertised, so it was only to his students that he laid out his plans for physics at Cambridge. When Maxwell began the actual course a few days later with a lecture on heat, it was attended by academics in formal dress, in the belief that it was the first lecture. Maxwell spent the next three years supervising the construction of the dedicated Cavendish Laboratory, and published in 1873 A Treatise on Electricity and Magnetism. Maxwell's health deteriorated a short time into his tenure, and he died in 1879, aged 48. Lord Rayleigh replaced Maxwell immediately upon
Applied Physics Laboratory was used in 2016 for a demonstration in which a paralyzed man was able to "fist-bump" Barack Obama using signals sent from an implanted brain chip. The limb returned sensory feedback from the arm to the wearer's brain. The APL researches and produces unmanned aerial vehicles for the US military. One of its most recent projects is an unmanned aerial swarm that can be controlled by a single operator on the ground.
