Plasma physics is the study of plasma, which is one of the four fundamental states of matter, alongside solids, liquids, and gases. Plasma consists of charged particles, including ions and electrons, and is found in stars, including our Sun, as well as in fluorescent lights and plasma TVs. Understanding plasma helps scientists explore various phenomena in space and develop technologies like fusion energy. Researchers in plasma physics investigate how plasmas behave under different conditions, including temperature and magnetic fields. This field has applications in areas such as nuclear fusion, space exploration, and semiconductor manufacturing. By studying plasma, scientists aim to harness its potential for energy production and other technological advancements.
