I am quite new to the branch of quantum physics and therefore am quite inexperienced with certain terminology and definitions. I have looked these topics up time and time again, but still cannot get a grasp on what they mean. Could someone please describe to me what the concept of "symmetry" in as simple as possible of a definition and also describe :symmetry breaking" also in a simple way. Just try to put it in words a novice would understand. Real examples would also be much appreciated. Thanks!
