Is Chemistry the Science of Everything?: Chemistry is the study of all matter, but matter at a very particular scale - that of atoms and molecules. Professor Davis begins by outlining his approach to this enormous topic and then introduces the periodic table of elements, one of the most powerful conceptual tools ever devised.
Languages of Physics: Understanding physics is as much about language as it is about mathematics. Begin by looking at how ordinary terms, such as theory and uncertainty, have a precise meaning in physics. Learn how fundamental units are defined. Then get a taste of the basic algebra that is used throughout the course.
