The education of Walter Kohn and the creation of density functional theory
The theoretical solid-state physicist Walter Kohn was awarded one-half of the
1998 Nobel Prize in Chemistry for his mid-1960's creation of an approach to the
many-particle problem in quantum mechanics called density functional theory
(DFT). In its exact form, DFT establishes that the total charge density of any
system of electrons and nuclei provides all the information needed for a
complete description of that system. This was a breakthrough for the study of
atoms, molecules, gases, liquids, and solids. Before DFT, it was thought that
only the vastly more complicated many-electron wave function was needed for a
complete description of such systems. Today, fifty years after its
introduction, DFT (in one of its approximate forms) is the method of choice
used by most scientists to calculate the physical properties of materials of
all kinds. In this paper, I present a biographical essay of Kohn's educational
experiences and professional career up to and including the creation of DFT

Creating a Symbol of Science: The Development of a Standard Periodic Table of the Elements
It is probably a surprise to most people that the periodic table they remember from high school chemistry is not the only periodic table – and never has been. Currently there are probably over a thousand different forms. The table in your chemistry textbook or on the wall chart in your chemistry classroom is not the periodic table. It is simply the most commonly used form. In fact, the International Union of Pure and Applied Chemistry (IUPAC), the international standards-making body for chemistry, has stated that although they encourage the use of this form, they will not endorse any one form of the periodic table as the periodic table. So where did this form come from? How did it come to be the current standard form of the periodic table? Most writing on the periodic table does not address such questions. For what is widely regarded as an icon of science, little is actually known about the origin of its form.
This dissertation aims to answer the questions of how the current standard form of the periodic table was developed and how it came to be ubiquitous in classrooms and textbooks. In it, I highlight the practical nature of chemistry, which influenced not only the development and acceptance of the periodic law but the creation of graphical representations of the periodic system that placed an emphasis on utility rather than art. I examine the role of research and pedagogy in the development of classification schemes for the elements, particularly the periodic system. I argue that the role played by pedagogy was more influential than that of research in the creation of new classification systems and the multiplicity of graphical representations of the periodic law. In the case of the periodic table, research-down theories about pedagogy, in which textbooks are seen merely as codifications of accepted scientific knowledge, do not hold true

Color in Ancient and Medieval East Asia
With essays by Monica Bethe, Mary M Dusenbury, Shih-shan Susan Huang, Ikumi Kaminishi, Guolong Lai, Richard Laursen, Liu Jian and Zhao Feng, Chika Mouri, Park Ah-rim, Hillary Pedersen, Lisa Shekede and Su Bomin, Sim Yeon-ok and Lee Seonyong, Tanaka Yoko, and Zhao Feng and Long BoColor was a critical element in East Asian life and thought, but its importance has been largely overlooked in Western scholarship. This interdisciplinary volume explores the fascinating roles that color played in the society, politics, thought, art, and ritual practices of ancient and medieval East Asia (ca. 1600 B.C.E.–ca. 1400 C.E.). While the Western world has always linked color with the spectrum of light, in East Asian civilizations colors were associated with the specific plant or mineral substances from which they were derived. Many of these substances served as potent medicines and elixirs, and their transformative powers were extended to the dyes and pigments they produced. Generously illustrated, this groundbreaking publication constitutes the first inclusive study of color in East Asia. It is the outcome of years of collaboration between chemists, conservators, archaeologists, historians of art and literature, and scholars of Buddhism and Daoism from the United States, East Asia, and Europe
