Leonardo da Vinci was an Italian Renaissance man born in 1452 and lived until 1519. He was a true Renaissance man and is considered one of the most great minds of the Renaissance era, displaying skills in many diverse fields of study. Although he is most famous for his paintings such as the Mona Lisa and the Last Supper, Leonardo is also renowned in the fields of civil engineering, chemistry, geometry, mathematics, mechanical engineering, optics and physics. He made his greatest contributions to mathematics and engineering through his astonishing inventions. Leonardo da Vinci was way ahead of his time, which is why most of his inventions were only made practical when someone reinvented them later, when technology caught up with his ideas. Leonardo da Vinci was one of the greatest mathematicians of all time, which is displayed in all of his inventions. His main goal through mathematics was to improve understanding and exploration of the world. He preferred to draw geographic shapes to calculate equations and create his inventions, which called upon his very deep artistic ability to articulate his plans. Leonardo da Vinci believed that mathematics was used to produce a result and so Da Vinci believed that through his drawings he could execute his studies of proportional and spatial awareness demonstrated in his technical designs and inventions. One of his greatest inventions to demonstrate his engineering and mathematical designs would be the parachute. Leonardo da Vinci's parachute consisted of a sealed linen cloth held open by a pyramid of equal length wooden poles, approximately seven meters long. The creation required a lot of math and physics to design the correct length of pole and carefully weave the fabric up to the poles so that the middle of the paper was then used in the printing presses. . The book was published in 1509 and is called Divina Proportione. It is said that scholars of Leonardo's time did not consider his work in any field other than painting, because he did not have a formal education. Instead, he had developed from an early age an important attitude towards his critics, where he wrote: "I cannot cite eminent authors as they can, these trumpeters and reciters of the works of others. I know that all knowledge is vain and full of errors when it is not born from experience, and so experience will be my teacher.” Leonardo da Vinci was a mysterious man who definitely left his mark on the world, his era and modern times. Many people say Leonardo was a genius, others say he was a complete mastermind who was ahead of his time, one thing is for sure he was very talented..
