# 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 3E*. 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.
