This video was produced by the BBC in 2010. It is narrated by Jim Al-Kahlili, a nuclear physicist who knows his stuff and is an awesome public speaker. The video is meant as an overlook of Atomic Theory, but more importantly it is a historic look over the wrestling of some of the greatest minds in history , over some of the key concepts of the atom. The video details the 1927 Solvay Conference,the greatest meeting of minds our world has ever seen. The conference was divided into two camps, one led by Einstein, and the other by Heisenberg and Schrodinger.
It is a bit lengthy, but definitely worth your time.
