In 1908–09 Professor Carl Russell Fish of the University of Wisconsin was commisioned as a Research Associate by the Carnegie Institution of Washington, D.C., and sent abroad to visit and assess the materials for American history to be found in the various archives of Italy. Out of his labors, done with the precision of a trained historian, came a volume which has long been a standard tool for students and researchers in this field: Fish's Guide to the Materials for American History in Roman and Other Italian Archives, published in 1911 by the Carnegie Institution. Pages 119–95 are devoted to an analysis of those archives of the Catholic Church which are commonly called the Archives of the Sacred Congregation de Propaganda Fide in Rome. Fish's analysis is preceded by a brief historical account of this important arm in the ordinary government of the Catholic Church from 1622 (the date of its establishment) until 1911.

Dr. Martin Houde is a Full Professor with the Department of Physics and Astronomy at Western University. With experience at the California Institute of Technology’s Submillimeter Observatory in Hawaii and three degrees from the University of Montréal, Dr. Houde brings his wealth of knowledge in the fields of star formation, extraterrestrial chemistry, and astrophysical instrumentation to Western. His research focuses on how the interactions between basic physical processes like magnetism and chemical reactions lead to the formation of stars while experience from the California Institute of Technology allows Dr. Houde to continually develop and enhance astrophysical instrumentation that enables researchers to further explore what lies beyond our galaxy. He is also the Canada Research Chair in Star Formation and teaches courses in Physics and Astronomy at Western. Brandon Lieng, First Year Representative with WURJHNS, interviewed Dr. Houde to learn more about his background, work, experience, and insights on the field of research.

Norman Levi Bowen, Research Associate of the Geophysical Laboratory of the Carnegie Institution of Washington, and one of the great pioneers in experimental petrology, died in Washington D.C. on 11 September 1956 in his seventieth year. He was born at Kingston, Ontario, on 21 June 1887, the younger son of William Alfred Bowen, a Londoner by birth, who had come to settle in Canada. Bowen attended school in Kingston and in the autumn of 1903 entered Queen’s University, registering in the Faculty of Arts. There he took an honours course in chemistry and mineralogy, graduating with the degree of M.A. in 1907 with the University medals in both subjects. In the same year he entered the School of Mining completing the B.Sc. degree course in 1909 in mineralogy and geology. Among his professors at Queen’s were R. W. Brock, subsequently Director of the Geological Survey of Canada, M. B. Baker and W. Nicol. E. L. Bruce and W. L. Uglow who later achieved distinction in geology were among his contemporaries. During his University career at Kingston he became engaged in field work for the Ontario Bureau of Mines, first in the summer of 1907 with Brock on a geological survey at Larder Lake, and in succeeding field seasons with M. B. Baker at Lake Abitibi (1908) and in the Gowganda Lake area in 1909, working there under the general supervision of A. G. Burrows. The results of his studies in these years appeared in two contributions, the first as a student’s paper in 1909 on diabase and aplite of the cobalt-silver area — which was awarded first prize by the Canadian Mining Institute and the President’s gold medal; the second appeared in 1910 in the Journal of Geology .


§ 1. The vacuum spark spectra of the lighter elements have furnished, in the hands of Millikan and Bowen, data for a remarkable extension of the field of optical series spectra. Their recognition and discussion of the sequence of doublet spectra of ionised atoms similar to lithium and sodium has emphasized certain difficulties in the interpretation of doublet separations which we shall mention briefly in § 4. The writer has, by means of spectra photographed by him in Prof. Millikan’s laboratory at the California Institute of Technology and in the laboratory of the Mount Wilson Observatory, essayed the extension of this work into the field of elements lying in the middle part of the periodic table.

This issue of Laser and Particle Beams contains 27 contributed articles based on presentations given at the eighth International Workshop on the Physics of Compressible Turbulent Mixing (IWPCTM) (see http://www.llnl.gov/IWPCTM), held at the California Institute of Technology, Pasadena, California from December 9 to 14, 2001, and organized jointly by the Lawrence Livermore National Laboratory (LLNL) and the California Institute of Technology. This conference is the eighth in a biennial series of conferences on the general subject of experimental, numerical, and theoretical studies of compressible turbulent mixing, initiated by LLNL in the late 1980s. Previous conferences were held in Princeton, New Jersey (1988), Pleasanton, California (1989), Royaumont, France (1991), Cambridge, United Kingdom (1993), Stony Brook, New York (1995), Marseille, France (1997), and St. Petersburg, Russia (1999). The ninth IWPCTM is to be held at the University of Cambridge in 2004.

Based on observations obtained using the 60-inch telescope at Palomar Observatory which is jointly owned by the California Institute of Technology and the Carnegie Institution of Washington and on observations obtained with the 200-inch Hale telescope which is owned by the California Institute of Technology.The intial observations of white dwarf stars and their immediate precursors, the hot subdwarfs, suggested that these stars possess the simplest (and, aesthetically, the most pleasing) spectra of any astronomical object. The high gravity leads to the spectrum being dominated, in the most stars, by broad lines of either hydrogen or helium, depending on the composition of the photospheric layers, with a few stars exhibiting lines from both species. However, the more detailed observations of recent years have revealed a higher degree of complexity. In particular, absorption lines of high excitation species (N V, C IV, etc.) have been detected in the ultraviolet spectra of several hot white dwarfs (Bruhweiler & Kondo, 1982) and, most recently, high resolution optical spectra have shown that one of the latter stars, the hottest known DA, G191-B2B, exhibits significant emission in the core of the H-alpha absorption line (Reid &: Wegner, 1988). Following up the latter observation, we have obtained high resolution spectra of a number of hot subdwarfs, with temperatures ranging from ~ 20,000K to more than 60,000 K. Most of these stars also exhibit Baimer emission, at Hβ as well as Hα in at least one case. We suggest the temperature reversal in the stellar atmosphere may be a function of the He/H ratio at the level of the photosphere.

Dr. Robert Hudson is a Professor of Chemistry, cross-appointed to Biochemistry. He has been at Western for 19 years, coming here from what he calls “the usual path”. Professor Hudson completed his postdoctoral research at California Institute of Technology in the lab of Professor Peter Dervan “one of the giants of bioorganic chemistry”, where he was for just over two years. Prior to that he completed his undergraduate education, Master’s and PhD at the University of Toronto. His free time is devoted to family, martial arts (something he has been doing for over twenty years), and travelling.
