After Einstein's death, physicists have gone through another sixty years on this unified road. Sixty years of ups and downs, bit by bit, what have theoretical physicists done? Where has the road to reunification gone now? What's the future? The author of this book starts with the introduction of Newtonian mechanics and quantum mechanics, then goes to group theory and symmetry conservation principles in mathematics, and then introduces the standard model, gauge theory, quantum field theory, Feynman path integral, Feynman diagram, etc., So that readers can have a basic understanding of the "unified" framework in theoretical physics, especially the "standard model" recognized by the mainstream physics community. Then, it also discusses the relationship between the unified theory and big bang cosmology, dark matter, and dark energy, as well as the difficulties and limitations of the standard model, and briefly introduces concepts including string theory, M theory, string nets, etc., So that readers can not only appreciate the beauty of the theory and the pursuit of scientists, but also appreciate the hardships of scientific research, and inspire young people's desire and curiosity to explore the laws of nature and step into the door of science.
Reader comments
This book is like a kind teacher, taking me into the wonderful world of particle physics. The author told the exploration path of physicists in an easy-to-understand way, which gave me a deeper understanding of the concept of "unification". This reminds me of A Brief History of Time, both of which explain esoteric scientific theories in layman's terms. Reading this book not only increased my knowledge, but also made me feel the charm of science and the persistence of scientists.
