Believe Quote by W. W. Sawyer
“You know what speed is. You would not believe a man who claimed to walk at 5 miles an hour, but took 3 hours to walk 6 miles. You have only to apply the same common sense to stones rolling down hillsides, and the calculus is at your command.”
![“The calculus is the story this [the Western] world first told itself as it became the modern world.” quote by David Berlinski](https://sms4smile.com/quotes/img-quotes/de1/david-berlinski-16009_calculus_the-calculus-is-the-story-this-the-weste_2753363.jpg)
