Telescope x Chiaroscuro

If this passage from Adam Grant’s Originals isn’t an argument for a liberal arts education, I don’t know what is:

When Galileo made his astonishing discovery of mountains on the moon, his telescope didn’t actually have enough magnifying power to support that finding.  Instead, he recognized the zigzag pattern separating the light and dark areas of the moon.  Other astronomers were looking through similar telescopes, but only Galileo “was able to appreciate the implications of the dark and light regions,” [Dean] Simonton notes.  He had the necessary depth of experience in physics and astronomy, but also breadth of experience in painting and drawing.  Thanks to artistic training in a technique called chiaroscuro, which focuses on representations of light and shade, Galileo was able to detect mountains where others did not.
