Description

We have all heard the story; classical physics supposedly predicts that the intensity of emitted radiation from a blackbody diverges in the ultraviolet and that is why Planck introduced the quanta of light.
This story, however, is a myth fabricated long after the historical events. The ultraviolet catastrophe was not coined until 1911 and its origin dates back to 1905; five years after Planck's work.
In this presentation we will learn about the true course of events that lead Planck to quantize the energy of the atomic oscillators in a blackbody.
