Specific Heat of Solids... Another problem with Classical Physics!

Towards the end of the 19th Century, classical physics had serious difficulties in explaing many observations. Einstein provided a solution of the specific heat of metals problem by assuming that energy absorption is quantised and is not continuous. This was a radical departure from the way physics was done in the 19th Century and demonstrates yet again the bold and visionary nature of Einstein's genius.
In the following I have published my slides from the talks on Einstein and the Theory of Relativity...
