On the Internet

The American Physical Society maintains a site dedicated to physics limericks. Visitors can access an archive of all submitted limericks and a more specific list of the winning limericks of the Society’s first Physics Limerick Contest. Besides showing that physics is fun, most of the limericks are focused on a specific concept that would work well in undergraduate physics courses. https://www.aps.org/apsnews/limericks.html

Also available to those interested in physics is the Fundamental Physical Constants Web site, an extensive resource for physics researchers, educators and students. https://physics.nist.gov/cuu/Constants/index.html
