X-ray diffraction quantitative phase analysis is a technique widely used in materials science and engineering research. The method proposed by Zevin [L. S. Zevin, J. Appl. Cryst. 10, 147 (1977)] has proven very useful in practice because standards or pure crystalline phases are not needed, but, Zevin only described the case ofnsamples, each of which contain different concentrations of the samenphases. An extension of this method, in which the reference samples could contain less phases than the analyzed sample is proposed in this paper. The absence of phases in reference samples is not arbitrary but depends on certain conditions. The conditions required to solve the equations are discussed in detail using the concepts of the set theory, and the results of confirmation experiments agree well with the theory.

Materials research and education is currently one of the liveliest areas of science and engineering and is likely to be so for many decades. It is an outstanding example of an interdisciplinary field; persons who call themselves materials researchers are found in departments of chemistry, physics, metallurgy, ceramics, electrical engineering, chemical engineering, and mechanical engineering, and also in many departments that now call themselves by the name “materials science and engineering.” The field has grown so rapidly that the term “materials science and engineering,” has many different meanings. In fact, most of the funding that supports materials science and engineering research is awarded to investigators in the more traditional disciplines, and the vast majority of scientists and engineers working in the field were educated in these traditional core disciplines.There is no question that the field of materials science and engineering is a success. However, is materials science and engineering now a discipline as well as a field? Should MS&E departments exist and what should be their educational mission? Should MS&E departments offer undergraduate and graduate majors? These questions are being discussed by many university faculties as they work to devise effective research structures and educational programs to respond to the growth of interest in a field that does not fit neatly into any single traditional discipline, but is far too important to ignore.Recently, the University Materials Council appointed a committee to consider these issues and specifically address the challenge of creating effective, attractive programs of undergraduate education in materials science and engineering.

ABSTRACTA review of the educational literature on naive concepts about principles of chemistry and physics and surveys of science museum visitors reveal that people of all ages have robust alternative notions about the nature of atoms, matter, and bonding that persist despite formal science education experiences. Some confusion arises from the profound differences in the way that scientists and the lay public use terms such as materials, metals, liquids, models, function, matter, and bonding. Many models that eloquently articulate arrangements of atoms and molecules to informed scientists are not widely understood by lay people and may promote naive notions among the public. Shifts from one type of atomic model to another and changes in size scales are particularly confusing to learners. People's abilities to describe and understand the properties of materials are largely based on tangible experiences, and much of what students learn in school does not help them interpret their encounters with materials and phenomena in everyday life. Identification of these challenges will help educators better convey the principles of materials science and engineering to students, and will be particularly beneficial in the design of the Materials MicroWorld traveling museum exhibit.
