Just as we can't predict what one molecule in a gas will do -- it's hopeless to predict a single molecule -- yet we can predict the properties of the whole gas, using thermodynamics, very accurately.
La fel cum nu putem prezice ce o molecula intr-un gaz va face -- este imposibil sa anticipam o singura molecula -- totusi putem prezice proprietățile întregului gaz foarte exact, folosind termodinamica.
