A publication of the University of Michigan’s Science Series, The Asymptotic Developments of Functions Defined by Maclaurin Series by Walter Burton Ford is an inquiry into the problem of functions defined by Maclaurin series. Here, Ford introduces his own theorem of asymptotic developments, as well as other mathematical theorems, and applies them to mathematical problems. This book was published with the hope of stimulating further research in the field.

A publication of the University of Michigan’s Science Series, Studies on Divergent Series and Summability is based on lectures and courses given by Walter Burton Ford at the University of Michigan about infinite series and divergent series. According to Ford, the study of divergent series can be divided into two parts, the first regarding asymptotic series and the second regarding the theory of summability, both of which are discussed within this volume.

Students and professionals alike have long felt the need of a modern source of practical advice on the use of optical tools in scientific research. Walter T. Welford's Useful Optics meets this need.

Welford offers a succinct review of principles basic to the construction and use of optics in physics. His lucid explanations and clear illustrations will particularly help those whose interests lie in other areas but who nevertheless must understand enough about optics to create the experimental apparatus necessary to their research. Consistently emphasizing applications and practical points of design, Welford covers a host of topics: mirrors and prisms, optical materials, aberration, the limits of image formation and resolution, illumination for image-forming systems, laser beams, interference and interferometry, detectors and light sources, holography, and more. The final chapter deals with putting together an experimental optics system.

Many areas of the physical sciences and engineering increasingly demand an appreciation of optics. Welford's Useful Optics will prove indispensable to any researcher trying to develop and use effective optical apparatus.

Walter T. Welford (1916-1990) was professor of physics at Imperial College of Science, Technology and Medicine from 1951 until his death. He was a Fellow of the Royal Society and of the Optical Society of America.
