Newton's Cannon |
Newton's Principia suggested that if you fire a cannon from a high mountain it could fall, circle the earth, or fly away depending on how hard it was fired. While Newton may have approved the use of his drawing from the Principia, he may not have appreciated a cannon that sounds like a squeaky toy.
