Physics is a fundamental science that can answer many of our questions about the structure of the world around us, and at the same time significantly shake the already established ideas about familiar phenomena. Recent research by scientists confirms existing theories, opens up completely new layers of knowledge and it is no longer modern not to imagine what surrounds us and how it works.Alexander Nikonov in his book examines physics and astrophysics comprehensively, refreshing already forgotten school knowledge, explaining the latest discoveries and clarifications of previously known physical laws, introducing us to new concepts and facts. If you used to find school physics boring, now you can look at it from a new perspective and discover the damn fascinating world of science!We'll 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 more complicated and interesting questions for consideration.:– Where does time come from and why do we need entropy?– Why has string theory become a revolution in the world of physics?– How do universes die, and what does it threaten us in the future? – and much more.
