The high density and extremely slow motion of atoms at nanokelvin temperatures can be exploited to alter radically the optical properties of the atoms. Clever tricks at room temperature and above can work, too.
Recent experiments on realistic samples take us further toward the goal of studying details smaller than 10 nm in objects that either emit light or absorb it.
A type of exclusion principle sometimes operates for married physicists, allowing only one spouse to occupy a job in a given location. Couples are trying to find ways to stay in their chosen fields—and in their marriages.
