In the new book, the author talks about the mysterious world of quantum mechanics - the most amazing, difficult to explain and little understood chapter in the book of physics. Quantum mechanics is known not only for the fact that it studies the very foundation of the universe, that is, the basis of the foundations of our world, but is also the first section of physics in which modern science encountered an observer, that is, consciousness. And therefore, consideration of this science is impossible without a fair share of existentialism - attempts to understand what consciousness, being and reality essentially are. There have been no attempts in world literature to answer the kind proposed by the author. This is a completely new look at the philosophy of quantum mechanics.
