The purpose of this Glossary is to provide clear, detailed, scholarly yet simplified definitions of terms and information on key topics in the areas related to human movement. The Glossary’s definitions and articles are written with the intention that everything on these pages can be understood by everyone and anyone. These definitions and articles are written by experts but not for experts in analogy to the way the Scientific American magazine is written by scientific experts but not primarily for scientific experts.

A critical feature of this Glossary is its status as a freely accessible resource with the intent of public education.
