One of the most famous photos in the history of physics captures the illustrious participants at the fifth Solvay Conference in Brussels, October 1927. Twenty-nine physicists, the main quantum theorists of the day, came together to discuss the topic “Electrons and Photons”. Seventeen of the 29 attendees were or became Nobel Prize winners.
