The Theory of Time. For Those Who Want to Do It All

At the center of attention is the question of what time is and how its understanding has evolved from calendars and early astronomical observations to the ideas of Newton and Einstein. The text systematically examines the main stages: classical mechanics, special and general theory of relativity, the connection of time with space, gravity, and the speed of light. A separate place is occupied by entropy and the arrow of time — concepts important for understanding the direction of physical processes. There is also a discussion of modern cosmology: the expansion of the Universe, black holes, and ideas about time travel.
