Reasonable cars

What is an “electric eye” and when a fire will not begin because of a match thrown into gasoline? How does the ship control system arrange? Is it possible to control different devices using sounds and how? What is the secret of automated production in factories and how do different machines help workers?
This book tells about the diverse and useful mechanical inventions of mankind, which used to seem fantastic, but now they have become familiar: a radio car, talking toys, automatic machines with food and goods and much more. In other words, in front of you is the history of the origin and development of mechanical engineering and robotics over the past three hundred years.
stated in an accessible language and supplemented by photographs, illustrations and schemes, this book will appeal to both children interested in science and parents who want to better understand modern technologies
