<jats:title>From Simplicity to Complexity</jats:title> <jats:p> The relatively simple properties of isolated electrons become rich and complex when the particle-particle interactions are strong enough to form a correlated system. Emergence of complex behavior from relatively simple subunits is an intensely studied topic in condensed-matter physics and applies to many systems in superconductivity and magnetism. <jats:bold>Si and Steglich</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1161" related-article-type="in-this-issue" vol="329" xlink:href="10.1126/science.1191195">1161</jats:related-article> ) review the physics of heavy fermion intermetallic compounds. These make ideal materials for study because they can exhibit metallic, magnetic, and superconducting behavior showing novel quantum phases and unconventional quantum criticality. </jats:p>
