Lewis Carroll and Math/Logic/Games/Puzzles
While he is known today primarily as an author, Lewis Carroll, or rather Charles Dodgson, was also a brilliant scholar. He taught math and logic to undergraduates at Christ Church, Oxford, for many years, at the same time he was creating fanciful stories to entertain children. He carved a unique place for himself in his field when he combined his two areas of expertise, writing entertaining scenarios for challenging math and logic problems, or turning the concepts into games, to make the learning easier, more enjoyable, and more lasting. While he did not produce any revelatory findings, many of his ideas and theories are still respected today, and his creative, user-friendly approach to learning remains fresh today. Current mathematical scholars around the globe are discovering a new appreciation for his contributions to the field.
