Section menus help you navigate within a portion of this site. Examples include the “More about the book” menu, the “More about the theory” menu, and “Recommended pages”.
You can find the section menus to the right or at the bottom of your screen depending upon your browser and screen size.
For example, there should be a “More about the book” menu to the right or bottom of this page. That same menu appears on all pages of “The Book”
To switch sections use the Navigation menu on the top of your web page.
You can use the section menus to access further information about a topic. For example, the “More about the book” menu includes links to information about the book’s contents, special features including pictures and photographs of the people and places discussed, and supplemental videos from TED and Youtube by people featured in the book.
