We live in an emergent universe in which interactions between the basic building blocks of matter and their environment give rise to unpredicted and unexpected emergent behavior at every scale. As physicists we seek to identify the organizing principles responsible for that behavior, construct soluble models that incorporate these, and explain experiment. Following some opening remarks about my many important Caltech connections, I illustrate this approach to understanding emergent behavior in quantum matter through four examples: collective modes in electron, helium, and nuclear liquids; the emergence of superconductivity in conventional superconductors, nuclei, and neutron stars; the emergence of heavy electron behavior and their superconductivity in Kondo lattice materials; and the unconventional superconductivity we find in the cuprates.
