This section of the website has been created to try and bridge the gap between Harry Stine’s excellent book “Model Rocketry” and the many professional text books. The aim is to explain the science of rockets in layman’s term and introduce people to the key maths and physics used in rocket science. For now, the website covers the basic principles, to let readers grasp the concepts without freaking out on maths. All analysis is based on one and two dimensions for simplicity. Real rocket flights take place in the three dimensional world, and the transition into that area of maths is not usually made until the second year of an engineering degree. I aim to keep the site at its present level. For further reading see the bibliography
