Isospin symmetry

Isospin symmetry is a concept in particle physics that describes how certain particles, like protons and neutrons, can be treated as different states of the same particle under specific conditions. Just as a coin has two faces, isospin treats protons and neutrons as two forms of a nucleon, allowing scientists to better understand their interactions. This symmetry helps explain the behavior of particles in atomic nuclei and reveals the underlying similarities among them, despite their differences in charge. Isospin plays a vital role in predicting particle reactions and in the study of fundamental forces.
