  • Conservation laws as fundamental laws of nature. Conservation laws are fundamental to our understanding of the physical world, in that they describe which processes can or cannot occur in nature. For example, the conservation law of energy states that the total quantity of energy in an isolated system does not change, though it may change form. Note that some conservation laws are absolute (conservation of energy and momentum for instance) but there are others (parity, which we will get to later) which are conserved by some of the three fundamental interactions but not all. Note that these conservation laws apply equally well to scattering processes, not simply decays.
