About the book: 2019 / Physics is the fundamental science, capable of answering many of our questions about the structure of the world around us, and at the same time, significantly shake already established ideas about familiar phenomena. The latest research by scientists confirms existing theories, opens up completely new layers of knowledge, and it is no longer modern to not imagine what surrounds us and how it works. Alexander Nikonov in his book examines physics and astrophysics in a comprehensive manner, refreshing already forgotten school knowledge, explaining the latest discoveries and clarifications of previously known physical laws, introducing us to new concepts and facts. And even if physics at school seemed boring and incomprehensible to you, now from the position of an educated adult you can rediscover this really damn fascinating science! We will go over all the basic concepts: – Why is not all radiation harmful? – How does the atom and the whole world work? – How has the evolution of physical knowledge changed our consciousness? – and much more. And then we’ll take on more complex – and more interesting – questions: – Where does time come from and why do we need entropy? – Why did string theory become a revolution in the world of physics? – How do universes die, and what does this mean for us in the future? – and much more.
