Yakov Isidorovich Perelman ; 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).
Perelman was born in 1882 in the town of Białystok, Congress Poland. He obtained the diploma of forester from the Imperial Forestry Institute in Saint Petersburg, in 1909. He was influenced by Ernst Mach and probably the Russian Machist Alexander Bogdanov in his pedagogical approach to popularising science. After the success of "Physics for Entertainment", Perelman set out to produce other books, in which he showed himself to be an imaginative populariser of science. Especially popular were "Arithmetic for entertainment", "Mechanics for entertainment", "Geometry for Entertainment", "Astronomy for entertainment", "Lively Mathematics", " Physics Everywhere", and "Tricks and Amusements".
His famous books on physics and astronomy were translated into various languages by the erstwhile Soviet Union.
