I was reading through a book on statistical physics when i came across this sentence: "An Einstein solid has two degrees of freedom for every oscillator."(adsbygoogle = window.adsbygoogle || []).push({});

How is this possible? I picture an oscillator (ex. mass on spring) to move only in one dimension, thus one degree of freedom. Where does the second degree of freedom come from?
