We habitually use many things without thinking about who invented them! We brush our teeth with toothpaste, fry fragrant toast in the toaster, go scuba diving on vacation, ride a bike, do crossword puzzles, draw with pencils... But all these inventions came to us from past centuries - a great time that gave impetus to the development of not only industry , transport, but also to new thinking. Every invention has an author! The owners of new thinking also gave humanity such “little things” as a lighter, a razor, a Barbie doll... Inventors know how to think outside the box and are able to find innovative solutions to various problems. They create different things: weapons designed to protect the peace of their homeland, mechanisms that make our lives more comfortable, invent unique devices, medicines, vaccines... In this book we want to talk about the most popular innovative inventions that came to us from the 18th–20th centuries, but are still relevant today.
