## Let’s Begin…

Archimedes once said “Give me a place to stand, and I shall move the Earth.” While the idea of a person moving such a huge mass on their own might sound impossible, chances are you’ve seen this idea in action at your local playground. Andy Peterson and Zack Patterson use the seesaw to illustrate the amazing implications and uses of the lever.
