The book "Principle of Relativity" by scientists Albert Einstein and Hermann Minkowski is a classic publication that changed our understanding of space and time. In this outstanding work, the authors offer a new perspective on the nature of the physical world, where the ideas about common dimensions of space and time, without which it is impossible to imagine modern physics, are the main ones. The book significantly influenced the development of modern science and became an important step in the direction of a better understanding of the mysterious phenomena of the universe. The "Principle of Relativity" remains relevant today, prompting readers to deepen their understanding of the nature of time, space, and the relationships between them.
