A brilliant intelligent child, his mind is full of bright ideas that preceded his era (the Stone Age), and he has been working on translating these ideas in the form of a group of useful inventions. Indeed, these inventions will change the way people live and work over the following hundreds of years. This book explores simple machines that contribute to reducing the effort, helping to raise or move heavy objects, or increase the speed of completion of the work.

This book also reviews what the famous Italian inventor Leonardo Da Vinci has made during the fifteenth century.
