This shows the <b>materials science tetrahedron</b>, which illustrates how a material's <b>properties, processing, performance, and structure</b> are interrelated. It is based on its having prior use in my engineering studies as a teaching device and symbol of the discipline, using <a rel="nofollow" class="external text" href="https://web.archive.org/web/20061123163305/http://www.mse.eng.ohio-state.edu/about/Tetrahedron.gif">this file</a> as a reference.
