Leonardo and mathematics

According to Freud, Leonardo «awoke too early from the darkness while the other men were still asleep». This book demonstrates the interest that Vinci's genius had for mathematics, a discipline which between the 15th and 16th centuries was experiencing an important period in its history, but it also deals with Leonardo, artist, anatomist, engineer, poet, dreamer, physicist, astronomer... because If the human mind in general is complex, that of this man is much more so. After a large section dedicated to the mathematics of Leonardo's time with particular attention to algebra, geometry and arithmetic, we enter the heart of the topic on the basis of Leonardo's codes. Thus, research on the golden ratio, constructions "with ruler and compass", quadrature of the lunulae and the uses of the "false position" method followed, as well as the polyhedra created for the treatise De divina proportione by Luca Pacioli and some studies on tessellations. With acumen and freshness Leonardo challenges the culture and art of his time, leaving an indelible imprint of his genius after half a millennium.
