The "space trip trio" returned smoothly, artificial intelligence technology gradually matured, and scientists successfully developed a new crown vaccine... Scientific breakthroughs are endless. However, people generally pay less attention to science, believing that science is very profound and too far away from them. Is this really the case?
The Age of Science: Key Technologies for the Future
The Age of Science: Key Technologies Leading the Future tells us that human daily life is inextricably linked to the development of science.
The Age of Science: The Key Technologies Leading the Future is a history of scientific development. It is not a simple list of scientific achievements, but tells a complete development process and interprets the connotation of modern science.
The development of science is continuous. The construction of scientific concepts and the birth of scientific inventions are not in one step, and many scientific and technological achievements are "standing on the shoulders of giants": the knowledge system is constantly updated and iterated to provide guidance for scientific practice, and at the same time, a large number of scientific practices will continue to accumulate experience and lay the foundation for the research of future generations.
Human knowledge of the world is always limited, so it is in the process of continuous exploration. For example, the exploration of the universe mentioned in the book has gone through a long process. On the basis of the research results of Galileo, Kepler and other scientists, Newton established a classical mechanical system, laying a solid theoretical foundation for space exploration. In the 20th century, Einstein proposed a subversive theory of relativity, bringing with it the concept of "space-time". Since then, cosmological theories such as the Big Bang have been born, space probes have been successfully launched, and people have a deeper understanding of the universe.
If we only pay attention to the occurrence of major scientific events and ignore its development process, we will not be able to truly understand modern science. Fragmented information cannot show the formation and evolution of a discipline, and the intrinsic connections between disciplines, which is not conducive to our understanding of the relationship between modern science and human society.
Unlike other general histories of science, this book focuses on the "highlight" years of scientific history— the 20th century.
In the 17th century, Isaac Newton laid the foundation for modern science, and since then, the development of science has never made such a major progress as in the 20th century: the successful landing of human beings on the moon, Einstein's theory of relativity, the clinical use of antibiotics and nuclear medicine such as penicillin, the birth of the world's first cloned sheep... The scientific achievements of the 20th century laid the foundations of science in the world today and in the future.
The emergence of these sciences and technologies not only directly changes people's living conditions, but also profoundly affects people's ideological concepts and ways of thinking, and determines the future development direction of science. Therefore, understanding the science of the 20th century is the only way for us to understand science now and in the future.

The book is divided into five chapters, corresponding to the five themes of space exploration, nuclear energy development, chemical applications, life sciences and communications, showing the outstanding achievements of astronomy, physics, chemistry, biology and other disciplines.
Between the lines, the scientific development of the 20th century is clearly presented before our eyes. We can understand the important breakthroughs in science in the 20th century, and we can also intuitively feel the changes in human life.
For example, the successive appearance of radio, film, telephone, television and computers has suddenly shortened the distance between people, and the entire earth has become a "global village".

In 1901, the Italian engineer Guglielmo Marconi made the first wireless transmission across the Atlantic in history in Britain, making outstanding contributions to radio. In 1920, the first radio programs appeared. Broadcasting has gradually become the main channel for people to obtain information.
With the invention of the television picture tube, television was successfully introduced, one of the most talked about inventions of the 20th century. Since then, sound and images have gradually entered thousands of households.
The birth of computer and Internet technology has brought people a new way of information exchange, realized the sharing of information resources, and made the transmission of information break through the limitations of time and space. In 1983, personal computers were widely used in the home, and the cover of Time magazine named it "Machine of the Year."

The development of science and technology has greatly improved people's quality of life and changed people's lifestyles and behavior habits, but at the same time it has also brought certain environmental problems.
In the 20th century, plastics, with their low manufacturing costs and easy shaping, gradually replaced some natural materials with limited resources and became indispensable products in people's lives. However, the environmental pollution caused by plastics is becoming more and more serious, and even threatens human health.
Plastic pollution is a serious situation, and marine life is facing great threats
Nowadays, science and technology are developing at an unprecedented speed, all kinds of scientific products have penetrated into all aspects of human life, and the development of human society is inseparable from science.
We live in an age of science that needs to keep pace with the development of modern science, and this book, The Age of Science: Key Technologies for the Future, helps us understand the complexities of modern science.

Specially licensed by Time Magazine, Stephen Hawking's works on relativity are published in its entirety!
Time, also known as Time, founded in New York in 1923, is one of the three major current affairs weekly magazines in the United States and has a wide global influence. In 1999, Time magazine published an article by British physicist Stephen Hawking entitled "A Brief History of Relativity", which introduced Einstein's great contribution to the progress of human knowledge from a scientific point of view.
