Order-of-magnitude estimation for terrestrial and space engineering

1 Course Unit

The goal of this course is to develop the ability to make quick order-of- magnitude estimates that are not completely rigorous and precise but still very useful. In practicing engineering, one is often confronted with real-life problems where multiple technical approaches are possible, but rigorous theoretical analysis of all options would require too much time. Making quick order-of-magnitude (back-of-the-envelope) estimates of the performance limits can quickly eliminate some approaches and allow one to focus on the ones that offer the best chance of succeeding. Examples covered in this course will focus on Earth’s climate and planetary science, aircraft and spacecraft, orbital mechanics, and space travel. Fall, even numbered years only 1 Course Unit
