The Microscopic World Unveiled by Electron Waves.

Electron interference has been investigated at an industrial laboratory of Hitachi, Ltd. for the past 30 years thanks to the encouragement and support of C. N. Yang, who retired from the State University of New York in 1999. This paper reports here fundamentals and applications of electron interference experiments we have carried out including our relation to C. N. Yang, and is based on a talk made in honor of him at the "Symmetries and Reflections" Symposium held at Stony Brook in May 1999. [ABSTRACT FROM AUTHOR]
