In numerous reference books and lists of Russian inventions, most often three-quarters of the wonderful ideas born of domestic inventive thought are not mentioned, but it turns out that we invented an airplane (of course not), a bicycle (also not) and a ballistic missile (by no means). This book has two tasks: the first is to tell about the inventions made at different times by our compatriots - as objectively as possible, without downplaying or exaggerating their merits; the second is to dispel the numerous myths and historical falsifications associated with the history of invention.
