“Calculus taught you how to take a snapshot,” Elias concluded, setting the chalk down. “Differential Equations will teach you how to predict the storm.”

“To solve a standard equation is to find a hidden number. But to solve a differential equation is to find a . You aren't looking for a '7' or a '10.' You are looking for a function—a curve that describes the path of a planet or the vibration of a violin string.” An Introduction to Differential Equations: With...

“Most people see the world as a photograph,” Elias said, his chalk hovering over the slate. “They see a car at a specific mile marker, or a population at a specific census count. They see what is .” He pressed the chalk hard against the board. “Calculus taught you how to take a snapshot,”
