The Fifth Solvay Conference, where the leading physicists of the time gathered to discuss quantum theory, produced an iconic photo of the participants. 17 of the 29 pictured either already were or would be Nobel prize winners, including Marie Curie who was badass enough to have two. But did you know there is film footage of the conference as well? [more inside]
