Freeman Dyson is considered to be one of the greatest living thinkers and intellectuals on the topics of science and technology. His ideas have had a profound and widely regarded impact on many fields – physics, biology, history, philosophy, and theology. Professor Dyson’s lecture entitled “Living through Four Revolutions” provided a first-hand witness reflection on the history of science and technology over the last half century. In particular, his contemplation was about the four modern scientific and technological revolutions which were space, nuclear energy, genomics, and electronic computing. He looks at how these revolutions started, how they slowly transformed the world during the past half century, and how they are still transforming it today.
