The most complete book ever made of Nilsson’s years of work in this field. No one like him has used the most modern and sophisticated scientific equipment to enter the human body and, with spectacular and beautiful photographs, give back the complicated and fantastic "inner map" of the phenomenon that lets us live every day: life. His work is not only a scientific tool but a real wager of vision: like Leonardo da Vinci five hundred years ago, he wanted to give body to his fantasies and images to his questions. The spiritual testament of a great visionary of our time.
