Yakov Isidorovich Perelman (Russian: Яков Исидорович Перельман; December 4, 1882 – March 16, 1942) was a Russian and Soviet science writer and author of many popular science books, including Physics Can Be Fun and Mathematics Can Be Fun (both translated from Russian into English).
This is a rare book from Yakov Perelman known for his 2 most famous books (Physics for Entertainment, volumes 1 and 2). This one does not deal with Physics. Instead it deals with space travel and astrophysics. The ideas expressed in the book such as designing a device to gain freedom from gravity, etc. are particularly interesting knowning the book was written in the first half of the last century.
