The observation that neutrinos have mass, which led to the 2015 Nobel Prize for Physics being awarded jointly to Japan’s Takaaki Kajita Japan and Canada’s Arthur McDonald, is important for two key reasons.
The microwave oven has been around for almost 80 years. When it heats food or liquid, the frequency of electrons increases but their energy slows down due to their own microwave emissions.
Researchers found a new way of generating an electric current with an electron pump, which brings about a new level of accuracy that could soon be used to calibrate machinery.
