71Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… …
72Gravitomagnetism — (sometimes Gravitoelectromagnetism, abbreviated GEM), refers to a set of formal analogies between Maxwell s field equations and an approximation to the Einstein field equations for general relativity, valid under certain conditions. For instance …
