=His life was actually pretty boring, he made a bunch of videos and stuff.

He also developed, with Robert Burns Woodward, rules for elucidating reaction mechanisms (the Woodward-Hoffmann rules). He also introduced the isolobal principle. Robert Burns Woodward: On the blackboard is the structure of chlorophyll, one of many complex molecules that he synthesized (National Academy of Sciences Press) Robert Burns Woodward (April 10, 1917-July 8, 1979) was an American organic chemist, widely regarded as the preeminent organic chemist of the century. ... In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs. ... The Woodward-Hoffmann rules devised by Robert Burns Woodward and Roald Hoffmann are a set of rules in organic chemistry predicting the stereochemistry of pericyclic reactions based on orbital symmetry. ... The isolobal principle in organometallic chemistry devised by Roald Hoffman aims to improve the understanding of chemical bonding in molecules by identifying molecules that share a common frontier orbital type, approximate energy and occupancy just as isoelectronic molecules share the same number of valence electrons and structure . ...

Hoffmann is also a writer of poetry published in two collections, "The Metamict State" (1987, ISBN 0813008697) and "Gaps and Verges" (1990, ISBN 081300943X), and of books explaining chemistry to the general public. Also, he wrote a play called "O2 Oxygen" about the discovery of oxygen, but also about what it means to be a scientist and the importance of process of discovery in science. Poetry (ancient Greek: ποιεω (poieo) = I create) is traditionally a written art form (although there is also an ancient and modern poetry which relies mainly upon oral or pictorial representations) in which human language is used for its aesthetic qualities in addition to, or instead of, its notional and semantic content. ...
