Edgar Buckingham: Fluorescence of Quinine Salts

Malaria, an often-fatal disease, has been a worldwide plague for several thousand years. The discovery of the efficacy of substances present in the bark of various cinchona trees, native to the Andes, provided some relief. A real antimalarial drug was not available until 1820, when Joseph Baptiste Caventou (1795-1877) and Josephe Pelletier (1788-1842) isolated quinine from the bark (1). Eighty ...

Alignment of Buckingham Parameters to Generalized Lennard-Jones Potential Functions

The Lennard-Jones(12-6) and the Exponential-6 potential functions are commonly used in computational softwares for describing the van der Waals interaction energy. Some softwares allow switching between these two potentials under prescribed condition(s) that attempt to connect the parameter relationship between the two functions. Here we propose a technique by which the parameter relationship b...

Central Ideas of Buckingham (1907): A Century Later

687 Edgar Buckingham became involved with soil physics for 5 yr at the turn of the twentieth century. His general goal was to advance understanding of moisture movement and evaporation from soils to improve irrigation and crop management. Specifi cally, he was interested in elucidating why evaporation from near the soil surface in arid areas during summer months was self-limiting (Buckingham, 1...
