Plinio Innocenzi is a full professor of Materials Science and Materials Technology at the University of Sassari and has a special interest in science popularization at different levels. He has a doctorate in physics but attended a Classic Lyceum dedicated to Humanities, Art, Latin, and Greek, which is why he has always maintained a multidisciplinary vision and developed a special passion for the connections between science and art. He has dedicated particular attention in recent years to Leonardo's scientific work and has participated in numerous conferences and festivals on the topic. This book is the result of Prof. Innocenzi's desire to make general readers more aware of the multifaceted origins of scientific and technological knowledge.
