Leonardo Da Vinci

Leonardo Da Vinci was a true Renaissance man. Although he is most famous for painting Mona Lisa and The Last Supper, he also was very interested in many other subjects including physics, math, geology, engineering, writing, and botany. Today at the British Library, I saw some of Da Vinci's original notebooks dating back to the 1400's. One of the notebooks contained his studies on optics. the behavior of light. Unfortunately I was not able to take a picture of it due to the library's regulations.
