In a 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 studying the very foundation of the universe, that is, the basis of the foundations of our world, but is also the first branch of physics in which modern science collided with the observer, that is, with consciousness. And therefore, the consideration of this science is impossible without a fair share of existentialism - attempts to understand what consciousness, being and reality are in essence. In the world literature, there have been no attempts at a response of the kind proposed by the author. This is a completely new look at the philosophy of quantum mechanics.
