Physics at every step

The collection includes three books by the remarkable popularizer of science Yakov Isidorovich Perelman (1882-1942) - “Physics at Every Step” (1934), “Do you Know Physics?” (1935) and “Young physicist in a pioneer camp” (1941). Texts in modern spelling and (in some cases) with updated digital data are given according to the corresponding editions. 271 drawings in these books were made (in close contact with Perelman himself) by the staff artist of the Leningrad publishing house "Vremya" Yuri (George) Dmitrievich Skaldin (1891-1951).
