This is a special feature of the NASA Glenn Beginner's Guide to Aerodynamics (BGA). This page begins a Guided Tour of the study of Gas Statics.
As a general rule, the Web consists of many individual pages that are connected, or related, to one another through hyperlinks. The Web is, therefore, much less structured than a bound book, in which one page follows another in a definite, numbered sequence. We have intentionally organized the BGA to mirror this unstructured approach. Users can navigate the pages of the BGA through hyperlinks based on their own interest and inquiry. But for those who prefer more structure to the information available at the BGA, we have organized an alternative to the unstructured approach -- a guided tour through the site. Users move from page to page through the tour by using special buttons at the bottom of each page.
