As we're busy working on our next episode, with stories inspired by the Periodic Table of Elements, we thought we'd bring you one of its chief inspirations.  As a young boy, neurologist, author and Radiolab favorite Oliver Sacks pored over the pages of the Handbook of Physics and Chemistry, fantasizing about the day that he, like the shy gas Xenon, would find a companion with whom to connect and share. That companion turned out to be the Periodic Table of the Elements itself, a relationship he's never outgrown. He introduces us to the elements that he's known and loved.
