No scientist in 1900 had an inkling of the mind-boggling developments that lay in wait: plate tectonics, genetic engineering, space probes, nanotechnology, Big Bang theory, electronic computers, nuclear weapons, artificial intelligence, and many other astounding products of the human mind. Indeed, by the end of the 20th century, nearly every 19th-century theory of natural and social phenomena would be overthrown or superseded. In this course, you learn the distinctive ideas that characterize 20th -century science, organized into five major themes: matter and energy, the universe, earth, life, and humanity. You discover the most significant developments in anthropology, archaeology, history, linguistics, sociology, political science, economics, psychology, and cognitive science - alongside physics, chemistry, mathematics, Earth science, and biology.
