Name: Entertaining Physics - Book 1.1979.

The proposed edition of Entertaining Physics by Ya.I. Perelman repeats the four previous ones. The author worked on the book for many years, improving the text and supplementing it, and for the last time during the life of the author the book was published in 1936 (thirteenth edition). Issuing subsequent editions, the editors did not set as their goal a radical revision of the text or significant additions: the author chose the main content of Entertaining Physics in such a way that it, illustrating and deepening the basic information from physics, has not become obsolete until now. In addition, the time after 1936. so much has passed that the desire to reflect the latest achievements of physics would lead to a significant increase in the book, and to a change in its face. For example, the author's text on the principles of space flight is not outdated, and there is already so much factual material in this area that one can only refer the reader to other books specially devoted to this topic.

Time magnifier.
When Wells wrote his Newest Accelerator, he hardly thought that something like this would ever come true. He had a chance, however, to live up to this: he could see with his own eyes - though only on the screen - those pictures that had once been created by his imagination. The so-called “time magnifier” shows us on the screen in slow motion many phenomena, which usually proceed very quickly.

“Time Loupe” is a cinematic camera that takes not 24 shots per second, like ordinary cinema cameras, but many times more. If the phenomenon filmed in this way is projected onto the screen, firing the tape at the usual speed of 24 frames per second, then the audience will see the phenomenon stretched out - occurring the corresponding number of times slower than normal. The reader has probably happened to see such unnaturally smooth jumps and other delayed phenomena on the screen. With the help of more complex apparatus of the same kind, a deceleration is achieved even more significant, almost reproducing what is described in Wells's story.
