Einstein theory of specific heatOxford Reference
A theory of the specific heat of solids proposed by Albert Einstein in 1906 In this theory Einstein attributed the specific heat of solids to the vibrations of the solid and made the simplifying assumption that all the vibrations have the same frequency This theory was partially successful since it was able to derive Dulong and Petit s law at high temperatures and showed that the specific
