The mathematician Srinivasa Ramanujan produced an extraordinary number of original results despite limited formal training. Working largely in isolation in southern India in the early twentieth century, he derived nearly 4,000 mathematical identities, many of which professional mathematicians would not begin to verify until decades later. His notebooks remain a source of new research today.
