"If you want to move forward, you need to push backward; that fundamental law of physics was first described in the 18th century by Sir Isaac Newton and still holds true today. Newton's third law of motion (sometimes called "action and reaction") is not always obvious, but it's the essence of anything that moves us through the world. When you're walking down the street, your feet push back against the sidewalk to move you forward. In a car, it's the wheels that do something similar as their tires kick back against the road. But what about ships and planes powered by propellers? They too use Newton's third law, because a propeller pulls or pushes you forward by hurling a mass of air or water behind you."
