Finger Puppet and Fridge Magnet.
Noam Chomsky occupies a unique place in American cultural life as a public intellectual, scientist, and political activist. In the course of more than 50 years at MIT, he revolutionised linguistics with "transformational generative grammer," holding that certain grammatical structures are innate and universal. This work influenced such fields as artificial intelligence, computer science, psychology, and analytic philosophy. As an activist, he was an early critic of the Vietnam War and remains relentlessly critical of media and U.S. foreign policy. Chomsky is a prolific author, having written more than one hundred books.
