The Periodic Table of Videos (PTOV) and Sixty Symbols (SS) are a collaborative effort between video journalist Brady Haran and the School of Chemistry and School of Physics and Astronomy at the University of Nottingham. Our two collections of several hundred short videos on scientific topics are hosted on YouTube and are available through our dedicated websites. The two channels have gained an enthusiastic global audience with over 29 million total video views. Though the initial goals of the projects were to produce one video for each element in the Periodic Table (PTOV) and 60 videos about the symbols used in physics and astronomy (SS), both projects have instead responded to a tide of viewer enthusiasm to evolve into ongoing projects far beyond their original scope.
