Who is using HyperPhysics?
A resource that was initiated as a resource for local high school physics teachers whom I had taught has expanded into an intensively used website worldwide.
CD or DVD versions have been sent to 82 countries to date, and translations into German, Italian, Chinese, and Espanol have been licensed and are underway.
The hit rate reached about 50 million file hits per year in the fifth year and logging was suspended. Informal statistics from the server log indicate about 15 hits per user on average, so 50 million hits translates to over 3 million users per year.
Email traffic has increased proportionately, and an informal tally of the emails indicates the following frequency of users.
- High school teachers.
- Engineering and technical personnel in industry.
- Independent learners.
Search engines give over 150,000 links to HyperPhysics, mostly from educators or educational institutions.
