How many inventors and scientists who are undeservedly forgotten or known for completely different merits. We take advantage of the fruits of their labors and do not even think about the one who was behind the discovery of many things familiar to us. Do you know who invented the camouflage that we have long been accustomed to? Do you know that the first odometer was invented before our era? Thinking about whose bright head came up with our favorite color television? Could you assume that the screw of a simple modern meat grinder works according to the Archimedes principle? Inquisitive readers will find answers to these and many other questions in this book.
