... Yea, but is this quantum stuff really relevant? Does all this quantum stuff really matter outside of the classroom and lab? Yep, we’re about to look at the development of the quantum mechanical behavior of the atom, a theoretical framework that expresses the behavior of matter at the atomic scale. ...
