Each conservation law is associated with a symmetry in the underlying physics (Noether's Theorem): ‣ Translation Symmetry in Space ➡️ Conservation of Momentum ‣ Translation Symmetry in Time ➡️ Conservation of Energy ‣ Rotation Symmetry in Space ➡️ Conservation of Angular Momentum ‣ Boosts and Rotations Symmetry in Spacetime (Lorentz transformations) ➡️ Conservation of 4-Momentum (energy + linear momentum). ‣ Change in Phase of Wavefunction (Gauge transformations) ➡️ Conservation of Electric Charge ‣ Simultaneous Reversal of Charge, Parity, and Time ➡️ Conservation of CPT parity
