# Rocket Science [[!img v_bo-small.png size="300x300" class="picture" ]] See also: ([[mathematical notation|MathSymbols]]) In order to better understand how to build rockets, we should be reasonably familiar with the theory of rocketry. Presented here are the physics behind rockets and discussions on their motion both near the ground and in space.
