We've made the case throughout this book that the academic enterprise is limited by a set of three beliefs. Much of what is of concern in the current academic climate could be ameliorated with a broader recognition of the value of debate, dissent, and consideration of divergent viewpoints. The ability to have engaged, thoughtful conversations on issues where divergence and sometimes strident divergence exists is critical for a functional society. If America's colleges cease to be places of free inquiry, American society will become less open, less innovative, and provide fewer opportunities. If we are going to move towards those answers, colleges need to be places where people are free to think outside the box, question assumptions, and propose new ways of seeing, analyzing, and engaging with some of the most pressing challenges facing society.

Committee E-04 on Metallography of the American Society for Testing and Materials (ASTM) conducted an interlaboratory round robin test program on quantitative energy dispersive spectroscopy (EDS). The test program was designed to produce data on which to base a precision and bias statement for quantitative analysis by EDS. Nine laboratories were sent specimens of two well characterized materials, a type 308 stainless steel, and a complex mechanical alloy from Inco Alloys International, Inconel® MA 6000. The stainless steel was chosen as an example of a straightforward analysis with no special problems. The mechanical alloy was selected because elements were present in a wide range of concentrations; K, L, and M lines were involved; and Ta was severely overlapped with W. The test aimed to establish limits of precision that could be routinely achieved by capable laboratories operating under real world conditions. The participants were first allowed to use their own best procedures, but later were instructed to repeat the analysis using specified conditions: 20 kV accelerating voltage, 200s live time, ∼25% dead time and ∼40° takeoff angle. They were also asked to run a standardless analysis.
