Some of the most famous scientists, as of May 2015, are Stephen Hawking, who is a physicist and cosmologist, and Noam Chomsky, who changed the arena of linguistics. Another notable scientist is Neil deGrasse Tyson, a science communicator and astrophysicist.
Stephen Hawking has contributed vastly to the field of quantum physics, and despite his battle with amyotrophic lateral sclerosis, a condition in which his muscular nerves are rendered inactive, is an accomplished lecturer and author. He has written two bestsellers, "A Brief History of Time" and "The Universe in a Nutshell," the latter of which is considered a masterpiece of modern physics.
Noam Chomsky believes that language in the human mind is innate, as opposed to the "blank slate" theory. Chomsky argues that the differences we see are due to time parameters, and explains why children are able to learn different languages easier than adults.
Neil deGrasse Tyson is a popular astrophysicist, and has appeared on many shows such as "NOVA," "The Big Bang Theory" and "Stargate Atlantis." DeGrasse Tyson has also published several books on astronomy, as well as the column "Universe" for the Natural History magazine. DeGrasse Tyson holds positions at the University of Maryland, the American Museum of Natural History, the Hayden Planetarium and Princeton University.
