The Method

"In the 12th century, a monk made a prayer book. Paper was scarce in those days, so instead of shelling out for brand-new paper, the monk pulled out an old manuscript off the shelf and just wrote it using that. He scraped off the ink and set off writing his book. Later analysis has shown that the worthless manuscript that he practically destroyed was actually a book called "The Method" by Archimedes. The book laid out the basics of calculus and physics more than 1500 years before Newton and Leibnitz, so yeah, we could have flying cars now if that guy had not written over the book." - LoganProductions, YouTube

But what if "The Method" had not been destroyed?
