The intriguing topic of molecular asymmetry has captured the interest of many scientists since the second half of the nineteenth century. Recent experiments in our laboratory have shown that under a continuous and dynamic dissolution-crystallization process, a racemic population of ethylenediamine sulfate crystals can be driven into crystals of a single handedness (i.e. stochastic chiral symmetry breaking).
