About the book: 1965 / The author of this book, scientific researcher, professor, Doctor of Physical and Mathematical Sciences A. I. Kitaigorodsky, cannot be accused of timidity. What kind of questions does he try to answer on the pages of his book! How to find the measure of patience? Is telepathy possible? How are expenses for scientific trips and conferences justified? What is the relative weight of natural and applied sciences? What does the word "explanation" mean? Are there differences between man and machine? How has physical thinking changed since Aristotle? How can a young man choose a profession?..And this is only a small part of the problems raised by the author. But the stories about them serve one purpose - to show the reader the role of physics in natural science and the role of natural science in science and life.
