	Gauge symmetry expresses redundancy in the mathematical description, but it also fixes the structure of interactions in theories such as QED and QCD.		Gauge symmetry expresses redundancy in the mathematical description, but it also fixes the structure of interactions in theories such as QED and QCD.

			In this setting, different field configurations may describe the same physical state. The extra mathematical freedom is not directly observable, but it constrains the allowed form of the theory.

			This is why gauge symmetry is so powerful in QFT. It connects local transformations with conserved quantities, introduces gauge bosons, and provides the organizing principle behind the Standard Model.

	The renormalization group tracks how couplings and other parameters change when a theory is viewed at different energy scales.		The renormalization group tracks how couplings and other parameters change when a theory is viewed at different energy scales.

			It shows that quantities such as charge or coupling strength are not always fixed once and for all. Their observed values can depend on the scale at which the system is probed.

			This makes the renormalization group central to modern QFT. It explains running couplings, effective field theories, asymptotic freedom, and why low-energy physics can sometimes ignore unknown details at much higher energies.
