Plasma Physics and Controlled Fusion

**Plasma Physics** is the study of plasma, which is one of the four fundamental states of matter, alongside solid, liquid, and gas. Plasma is a collection of charged particles, including ions and electrons, that exhibit collective behavior and respond to electric and magnetic fields. It is often referred to as the "fourth state of matter" because it differs significantly from solids, liquids, and gases. Plasma can be found in many environments, including stars, lightning, and fluorescent lights.
