Leonardo Da Vinci

Mathematic Applications Leonardo Da Vinci thought mathematics were essential in his paintings. He even said in one of his books that people who hadn't studied math shouldn't even start reading his work. He worked with 2D and 3D objects and their properties. In the “Last Supper” painting the wall that it is painted on looks like a dining hall instead of a wall with a painting on it. Leonardo also used the “Golden Ratio” in his “Last Supper” painting. The golden ratio (also called Phi) is exactly 1.618 and can be solved through algebra. n2 − n 1 − n 0 = 0 n2 − n − 1 = 0 n2 = n + 1 (1 + √n)/2 (1 + √5)/2

About Leonardo’s Life Leonardo was born on April 15, 1452 in Vinci, Italy. When he was 15 his father sent him to the workshop of Andrea del Verrochio in Florence. Here he showed his amazing talents, but left in 1477 for a new challenge, and more money. He then entered the service of the Duke of Milan in 1482. He learned many things there, including: nature, flying machines, geometry, mechanics, construction, canals, and architecture. He left in 1499 after the Duke fell from power. In 1503 he started working on the Mona Lisa, and in 1504 he received the news of the death of his father. From 1513 to 1516 he worked in Rome, doing many projects for the Pope. He then started working for King Francis I in France. He suffered from the paralysis of his right hand, but continued to draw and teach. He died on May 2, 1519 in Cloux, France.

Fun Facts Leonardo was left-handed. He wrote almost all of his notes in mirror writing, supposedly so they were kept secret. He was a vegetarian, which was rare for his time. He would buy caged birds and set them free. He was one of the first Italians to use oil paint. He hated war, but created deadly weapons. Leonardo was dyslexic.
