The standard model of particle physics violates time‐reversal invariance, but apparently not strongly enough to account for the excess of matter over antimatter in the universe. One of the best ways to search for other sources of time‐reversal violation is to measure electric dipole moments of atoms. I argue that the best atoms to use are those with octupole‐deformed nuclei, and describe a self‐consistent calculation of the collective enhancement of time‐reversal violation in one such nucleus, 225Ra, an experiment on which is in preparation.
