What do the mountains in the background of the Mona Lisa reveal about Leonardo da Vinci's knowledge of erosion? What can high-tech scanners tell us about his other work? Find out at the nifty exhibit Universal Leonardo from the University of the Arts London. One section explores how Leonardo's writings, sketches, and paintings reflect his view of the world, where all things--from the motion of water to the curling of hair--are connected through the geometrical rules that govern nature.

Another highlight is an investigation of what different imaging techniques have uncovered about the history of Leonardo's 1501 painting Madonna of the Yarnwinder. For instance, a profilometric analysis, which uses a laser to map the painting's tiny variations in height, shows that some restorers "repaired" undamaged sections, such as the child's right cheek. An ultraviolet scan also reveals touchups on the infant's calf and hip.
