Features: This book is part of the "Science New Horizons Series" from the China Science and Technology Museum. Main content: The substorm that connects the heavens and the earth, igniting the fire of nature and the light of reason, and ushering in a modern physics revolution in the new era. The book reviews the scientific achievements and development of physics by groundbreaking figures such as Galileo, Newton, Maxwell, Einstein, Bohr, and Marie Curie, aiming to draw valuable insights and lessons to benefit our understanding of the future of science and the nation. A century ago in 1905, Einstein wrote five famous papers in Bern, Switzerland, which are historically significant. Among them, "An Empirical Foundation for a Theory of the Production and Transformation of Light" proposed the photon hypothesis and the photoelectric effect theory, holding an extremely important position in the development of quantum theory; "A New Determination of Molecular Size" derived the mathematical formula for calculating the diffusion speed of molecules; "On the Movement of Small Particles Suspended in a Stationary Liquid Required by the Molecular Motion Theory of Heat" provided evidence for the existence of atoms; "On the Electrodynamics of Moving Bodies" proposed a new theory of space-time relationships, announcing the birth of relativity; and "Does the Inertia of a Body Determine Its Internal Energy?" introduced the concept of mass-energy conversion based on special relativity. Looking back at history, we see even more clearly that every scientific, technological, and industrial revolution has left an indelible mark on our party. The physics revolution and the series of scientific changes it triggered not only gave rise to numerous technological innovations, promoting industrial and economic development, but also profoundly deepened humanity's understanding of the material world, fostering the emergence of advanced ideas and cultures, thereby profoundly transforming human material, spiritual, and social life. From Galileo, Newton, Maxwell to Einstein, Bohr, and Marie Curie, the pioneers of the physics revolution, they are undoubtedly the epoch-making figures in the history of science and even in human history. Today, as we review their scientific achievements and the development of physics, we are not merely honoring and remembering them, but more importantly, we are drawing valuable insights and lessons to benefit our understanding of the future of science and the nation.
