Peter S Pershan Author

Peter S. Pershan is Frank B. Baird, Jr Professor of Science in the Physics Department and the School of Engineering and Applied Science at Harvard University. In the early 1980s he helped produce the first synchrotron x-ray reflectometer for the study of the horizontal liquid surface. He has since led the liquid surface field in exploration of such diverse liquid surfaces as superfluid helium, water and liquid metals. Mark L. Schlossman is a Professor in the Department of Physics at the University of Illinois, Chicago. He built an x-ray reflectometer at the NSLS that subsequently served as a prototype when he helped design the ChemMatCARS instrument featured in the book. His use of both reflectometers led to pioneering studies of the structure of liquid-liquid interfaces.
