About Author

The author studied quantum physics and general relativity in graduate school at Penn State. His Ph. D thesis was on general relativity. In June 1970, after working at two other organizations, he joined The John Hopkins Applied Physics Laboratory (JHU/APL). At JHU/APL he became recognized as an international expert on wave propagation (acoustic, electromagnetic and seismic). He wrote a book “Acoustic Waveguides: applications to oceanic science” published by John Wiley.

He presented his work at professional meetings in London and Paris. His work dealt mainly with the detection of submarines by both acoustic and non-acoustic methods. One non-acoustic method was the detection of neutrinos emitted by the submarine’s nuclear reactor. He was the Chief Scientist for his group. While at JHU/APL he taught astronomy at The University of Maryland, Baltimore County (UMBC). He retired in 2013 at age 77 and decided to write this book which he finished in 2020.
