You can browse this site in several different ways.

By subject: like a wanderer with your knapsack of knowledge on your back, you enter whatever topic interests you, then follow whatever path looks inviting. As you amble about, you may sometimes feel a little lost, but you may also make some amazing discoveries.

By level of explanation: like a seasoned traveller exploring all the museums in a new city to learn as much as possible. In this case, the topics are the museums, and you start exploring each one on the “first floor” (the novice level of explanation). But soon, your thirst for knowledge will take you on to the intermediate level, and then the advanced one. When you are done with that, you can go on to explore the links we provide to other Web sites and all the knowledge that the Internet has to offer.

By level of organization: like an archaeologist exploring the various levels of a dig site. In this case, the site is a sub-topic that you explore by level of organization, digging down to the nervous-system level, the cellular level and even the molecular level. Or if you prefer, start from the molecular level and work your way up to explore the psychological and social implications of your sub-topic.

By module: like a researcher consulting an encyclopedia. The modules on this site are a gold mine of information on such subjects as the history of various disciplines, the tools used in them, the researchers involved in them, and famous experiments that can help you understand them.
