Eric Weisstein's World of Science contains budding encyclopedias of astronomy, scientific biography, chemistry, and physics.
This resource has been assembled over more than a decade by internet encyclopedist Eric W. Weisstein with assistance from the internet community.
Eric Weisstein's World of Science is written and maintained by the author as a public service for scientific knowledge and education. Although it is often difficult to find explanations for technical subjects that are both clear and accessible, this web site bridges the gap by placing an interlinked framework of mathematical exposition and illustrative examples at the fingertips of every internet user.
This site serves as the hub to several Eric Weisstein encyclopedic science websites. From this page, a user can access sites on astronomy, chemistry, mathematics, physics, and scientific biography. Each of the sites devoted to a discipline offer definitions, explanations of theories, experiments, and formulas. The biography site offers the most pure history and it contains short entries on more than a thousand personalities. The entries are organized alphabetically, by discipline, by time period, and by nationality. The entries continue to be compiled by the managers of the site from contributions of volunteers in the scientific community.
