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 14: Atomic, Molecular, and Nuclear Physics

Thus far we have mostly considered problems that can be solved exactly. This was not by accident. However, when discussing real atoms, molecules, and nuclei, we must often rely on numerical techniques. In this chapter we consider a few quantum-mechanical models that have varying success in describing (approximating) atoms, molecules, and nuclei.
