Analysis:

Dyson sphere:

As early as 1960, Freeman Dyson put forward a theory called "dyson sphere". He believes that a planet like the earth has very limited energy, which is far from enough to support the development of its civilization to an advanced stage; In the star-planet system, most of the energy-radiation from stars-is wasted. At present, the planets in our solar system only receive about1109 solar radiation energy. Dyson believes that a highly developed civilization must have the ability to surround the sun with a huge spherical structure, so that most of the radiation energy of the sun is intercepted. Only in this way can we support this civilization for a long time and make it develop to a sufficient height.

Freeman Dyson, 1924-) was born in England, studied at Cornell University in the United States from 1947, officially settled in the United States from195, and became a professor of advanced research physics at Princeton from 1953. Professor Dyson is not only an excellent theoretical physicist, but also a wise philosopher who cares about human destiny and yearns for the infinite universe. He has been engaged in mathematics, particle physics, solid state physics, nuclear engineering, life science and astronomy all his life, aiming at exploring the unknown world. Professor Dyson was a giant of quantum electrodynamics in his early years and missed the Nobel Prize in Physics. The paper "Spin Wave" published in 1956 has been cited countless times and is one of the heavyweight papers in the history of physics. Dyson said that "spin wave" may be the most important contribution in his life. Professor Dyson has served in Princeton Institute for Advanced Studies for forty years. Dyson has won many awards: Hughes Medal of Royal Society of London, Max Planck Medal of German Physical Society, Oben Harmo Memorial Award, Harvey Award of Israel Institute of Haifa, etc. He has written books such as Almighty Infinity, Weapons and Hope, Cosmic Wave, Imagined Future, Sun, Genome and Internet: Tools of Scientific Revolution and Imagined World, which have aroused great repercussions in the scientific community and the public.

When Freeman Dyson was a child, he was not only interested in mathematics and physics, but also enjoyed reading literary works. Without the liberal arts foundation laid in his early years, his Waves of the Universe will be calm in the vast sea of books and will not become a bestseller, and his sales of Almighty Infinity will be quite limited. Almost every book of Freeman Dyson is very good-looking, not to mention the depth of his thoughts. His elegant words alone are full of charm. His Cosmic Wave, All-round Infinity, The Sun, Genome and Internet, Imagined World, etc. have all been translated into Chinese. In addition, he also wrote "From Love Ross to Gaia", "The Origin of Life", "Weapons and Hope" and so on. Like many learned writers, he quoted a famous saying related to the theme of this chapter at the beginning of each chapter of this book. If you don't have the ability to "read thousands of books", you can't "quote like a god".

Introduction of main works:

Cosmic Radio Wave —— Reflection on Science and Technology and the Future of Mankind

Dyson, the first giant of quantum electrodynamics, is not only an excellent scientist, but also a wise philosopher who cares about the fate of mankind and yearns for the infinite universe. This book is a memory of his 50 years of scientific work. He compared his scientific life to the voyage of his soul, romantically and vividly described the demeanor and achievements of many famous scientists, such as Oppenheimer, Feynman, Taylor, etc., the research course and debate of atomic furnace, life science and technology, and space exploration, and at the same time had profound thoughts on the development of science and technology and the future of mankind.

All-round infinity: why life is so complicated

Professor Dyson is a general in the scientific field. With superb intelligence and extraordinary courage, he crossed the threshold of science and thought about the close relationship between the universe and the human mind. This book is divided into two parts. The first part is "Why is life so complicated". In the book, the author explores the diversity and consistency, complexity and simplicity of life, leading readers to uncover the mystery of the origin of life step by step, and then infer the ultimate future of mankind. The second book "See Butterflies in a Nuclear Winter", from the balance of military power, the development of nuclear weapons, the Star Wars plan, to the international politics in the 2 1 century, which is more related to the fate of mankind, examines the modern predicament of human morality and ethics in the high development of science and technology. Professor Dyson's wonderful experience of observing butterfly dancing from the birth of pupa left a deep impression on people.

Imagined future

1979, Dyson expressed his concern about the human situation through his personal biography in Waves of the Universe. 1988, Dyson explored a variety of life in all-round infinity, and further thought about the interaction among human beings, technology and morality. In this book, the author draws lessons from others and imagines the future of mankind with fluent thoughts and beautiful writing. Dyson pointed out the fate of tomorrow's science through the colors of literature and science fiction, predicted the evil and beauty of future science and technology, and measured the evolution of human beings with ten years, a hundred years, a thousand years or even infinite time as a yardstick. At the same time, he called on science and technology to go hand in hand with morality. Dyson's imaginary future, like roaming the boundless universe in a time machine, shows a colorful world in front of human beings.

This book tells a vivid story, whether it is reality or imagination, whether it is science or art, its original intention does not lie in science and technology itself. The author puts human behavior in the development of material civilization in a broad space-time, and thinks that all science and technology have ethical characteristics.
