Reliability in Scientific Research Improving the Dependability of Measurements, Calculations, Equipment, and Software

Covering many techniques widely used in research, this book will help researchers in the physical sciences and engineering solve troublesome - and potentially very time consuming - problems in their work. The book deals with technical difficulties that often arise unexpectedly during the use of various common experimental methods, as well as with human error. It provides preventive measures and solutions for such problems, thereby saving valuable time for researchers. Some of the topics covered are: sudden leaks in vacuum systems, electromagnetic interference in electronic instruments, vibrations in sensitive equipment, and bugs in computer software. The book also discusses mistakes in mathematical calculations, and pitfalls in designing and carrying out experiments. Each chapter contains a summary of its key points, to give a quick overview of important potential problems and their solutions in a given area.

1. Basic principles of reliability, human error, and other general issues; 2. Mathematical calculations; 3. Basic issues concerning hardware systems; 4. Obtaining items from commercial sources; 5.

I. R. Walker is a researcher at the Cavendish Laboratory, University of Cambridge, where he has worked for over 20 years. He received his Ph.D. there in 1992, and was an Assistant Director of Research from 1995 to 2002. His principle line of research is the physics of superconductors and other strongly correlated electron materials at ultra-low temperatures, and the development of techniques for subjecting these materials to high pressures under such conditions.
