CATALOG 1952-1953 MS. 590.-Special Topics. Variable credit. The purpose of this course is to provide a means for advanced students to pursue work along any line needed, even though no formal course is at the time available; or to introduce the student to research literature in mathematics. Students may be directed individually and informally, or in groups according to an established schedule. MECHANICAL ENGINEERING Instructional Staff 1951-52 Reed, J. C., Head; Bourke, N. Bussell, W.
