With numerous examples, the author shows how one of the main formulas of complex analysis is the Euler formula - along with the famous "golden section", manifests itself as an impeccable standard of mathematical beauty. Proof of the irrationality of the number of "pi", the presentation of the vibration of the string in the diagram, the geometry of the impulse function and even the creation of a speech scumbag - all these so different topics are united by the use of the formula of the great mathematics. The final part provides a biographical certificate of Eler, including little -known facts from his life.
The publication is intended for a wide range of readers - lovers of mathematics and physics
