PSST . . . PASS IT ON !
Before Elements was written , Pythagoras ( the triangle man ) and his Pythagoreans ( students ) had already been working out geometrical truths ( as had others before them ), and sometime after them , the philosopher Plato wrote down some of the accumulated number wisdom . Then came Euclid , maybe , who collected all their work and wrote it down . Then came everyone who read Elements and were inspired by the number logic , from Ancient Greek mathematician
Archimedes ( inventor of the water screw ) to some much more recent celebrities , including Leonardo of Pisa ( Fibonacci sequence ), Johannes Kepler ( laws of planetary motion ) and Albert Einstein ( general theory of relativity ).
That is how knowledge gets passed down through the years , person to person , book to book . So even if the people who wrote the books get slightly forgotten , the wisdom still remains .
