Matvey Bronstein (1906–1938) in his short life managed to enter the history of both fundamental physics and scientific literature. His adventure stories about scientific discoveries and inventions became an example of a new literary genre. He talked about a substance found first on the Sun and only many years later on Earth. About the accidental discovery of invisible X-rays, which brought Roentgen the very first Nobel Prize in physics, and mankind - a device that allows you to see through. And he managed to talk about the invention of radio, without which there would be neither television nor the Internet. At the same time, at the same desk, Matvey Bronstein wrote outstanding scientific works on quantum gravity and cosmology, which have retained their value to this day.The second part of the book is evidence of the life and literary union of Matvey Bronstein and Lydia Chukovskaya, thanks to whom the stories collected in the book were born.
