Gell-Mann's work on conservation laws

Gell-Mann's work on conservation laws revealed that in physics, certain properties—like electric charge or energy—remain constant over time in isolated systems. He showed that these conservation principles aren’t just observations but are deeply connected to symmetries in nature. For example, the law of charge conservation aligns with the symmetry that physical processes look the same over time. Gell-Mann’s insights helped unify fundamental concepts, demonstrating that conservation laws are essential for understanding how particles and forces behave, guiding the development of modern theories in particle physics and our understanding of the universe’s fundamental structure.
