Philosophy of Structure, Part 3: Chemistry

Part 3 in this series on the philosophy of structure looks at examples and general principles of structure in chemistry. Subjects covered include quantum mechanics, the Schrödinger equation, wave functions, orbitals, molecules, functional groups, and the multiple levels of structure in proteins. General principles discussed include the nature of functions, the embedding of lower-level structures into higher-level structures, and the repeated use of a limited number of lower-level structures in the formation of higher-level structures.
