A magnetic and optical trap used to cool atoms to close to absolute zeroNASA/JPL-Caltech/SCIENCE PHOTO LIBRARYThe laws of physics assert that an organised system will grow increasingly disordered over time until it dissolves into featureless mush but a new experiment shows that some extremely cold atoms could avoid such entropy.Any system beginning with low disorder, or low entropy, is bound to eventually become more of a mess. Picture flowers arranged in a bouquet: their entropy will gradually keep increasing until the brightly-coloured bundle
