The Beginner's Guide to Aeronautics (BGA) is a collection
of guides to provide background information on basic aerodynamics
and propulsion for math and science teachers, students, and life-long
learners. The BGA is organized to mirror the unstructured nature
of the World Wide Web--many pages ere connected to one another through
hyperlinks. You can then navigate through the links based on your
own interest and inquiry. However, if you prefer a more structured
approach, you can also take one of our Guided Tours through the
site. Each tour provides a sequence of pages dealing with some aspect
of aeronautics.
