Leonardo da Vinci and Rube Goldberg both contributed to the engineering process. Each of them brought something important to the big picture. As the discussion continues keep in mind the three basic steps of engineering; ideate, implement, and test. Leonardo was best known for his his painting of the Mona Lisa, however, he was also a self taught engineer. He was an exceptional mathematician and spent an extensive amount of time studying geometry. This alone contributed heavily to engineering because engineering heavily consists of geometry and the study of how different shapes and sizes can affect the way something might work. For example, if an engineer were to create a pulley, they would have to first think of a design for that pulley and
