Support for Java Applets, including Physlets, has been discontinued by browsers and Oracle. Thus, traditional *Java-based* Physlets are
no longer supported on this website. Please note Open Source Physics (OSP) Java programs continue to run on computers with Java if users
download the jar file.

The OSP team is busy updating and developing simulations using HTML5 + JavaScript.

These simulations run on almost all platforms
including tablets and cellphones. Explore the **Third Edition of Physlets Physics**
or search OSP for JavaScript to find these simulations.

# Chapter 1: Introduction to Physlets

This chapter serves as an introduction to the various types of interactive curricular material you will find in *Physlet Quantum Physics 2E*. In addition, this chapter gives a brief tutorial on the types of basic computer skills you will need to run, interact with, and complete the interactive exercises on the ComPADRE site. NOTE: In order to run these exercises you need to be on a laptop/desktop computer with a Java-enabled browser.
