Browsing: Particles

Particles refer to small discrete units of matter or energy. In physics, the term encompasses a broad range of entities, from subatomic components like electrons, protons, and neutrons to larger composite structures such as atoms and molecules. The study of particles is a fundamental aspect of various scientific fields, including particle physics, which primarily investigates the properties, interactions, and behavior of the most basic building blocks of matter. These elementary particles, including quarks, leptons, and bosons, are governed by quantum mechanics and interact through fundamental forces of nature: gravity, electromagnetism, strong nuclear, and weak nuclear forces. Additionally, in colloquial use, “particles” may also refer to tiny solid materials in the environment, such as dust, pollen, or particulate pollutants, which are significant in studies of air quality and environmental health.
