This page showcases some "live" documents that have been created with the help of the QMTools software. The documents included here take two forms: exercises and tutorials. [For an alternate organization with summaries, see document list with text references to Modern Physics, 3rd Edition, by Serway, Moses, and Moyer.]

As these use Java applets, you will need the Java Runtime Environment (JRE) version 1.6 or later. No further manual installation is needed to display the examples on this page – just click the links below.

These documents use the newest (version 4.0) of QMTools. To display them properly, we recommend that you purge your system of any earlier versions of the software, including JOGL libraries that were placed in the JRE extensions directory during installation of version 1.0.

Disclaimer:  Beginning with Oracle's Java Applet Plugin update 7u51, applets are not permitted to run unless signed by a trusted certificate authority. Since then, vendors of several popular browsers (Chrome, Firefox) have committed to discontinue their support for the Java plug-in altogether. To address these concerns, we propose a short-term fix and a long-term solution; neither is ideal given the original QMTools vision.

WorkAround (the 'fix'):  Add the following two entries to the Exception Site List on the Security Tab of the Java Control Panel:

http://people.uncw.edu/moyerc/QMtools/
http://jogamp.org/

Make sure Java is enabled in your browser, then click the desired link below and grant the necessary permissions at the prompts. At present, this workaround allows the applets below to run on some (but not all!) configurations.

Webstart Apps (the 'solution'?):  The current version of the QMTools Editor allows any applet to be exported as a Webstart application that can be run from the local file system. In this scenario the 'applet' is not launched from the browser at all, so no Java plug-in is needed (but the Exception Site List must still be augmented as above). Unfortunately, this approach sacrifices the 'tight' integration between context provided by the web page and the interactivity of the applet. For more details, consult editor help.
