I've always wondered who was the creator of the first screw, it was used to make the first machine created to create screws...Imagine having to do all this work EL (again), it takes forever and a day to finish half of it. that's why these engineering machines make our job easier.

Ever since I've seen machines move in this way, I've been addicted to seeing machines in action, from the simplest to business machines and beyond. Many unscientific people underestimate the things they use every day. The genius of creating these machines is mind-blowing.
