"...an historical tour-de-force, and I thoroughly recommend it to everyone interested in U.S. astronomical history, positional astronomy, national observatories, naval history, navigation, time-keeping, or the conflict involving civilian and military control of science." Journal of Astronomical History and Heritage
"It provides insight for scholars and general readers interested in naval history and navigation, timekeeping, positional astronomy, and celestial mechanics, and it charts the relationship between astronomy and astrophysics, the rise of national observatories and military patronage." Bulletin of Science Technology and Society
"An amazingly comprehensive and detailed history of the oldest major astronomical observatory in the United States, this excellent book offers mature readers fascinating stories of scientific discoveries (e.g. of the moons of Mars and Pluto), technological developments (e.g. from mechanical clocks working before there were any time zones to today's satellites that provide nanaosecond accuracies worldwide), and personal and political struggles (both governmental and institutional)."

"Sky and Ocean Joined is an outstanding book." Technology and Culture, Robert W. Smith
As one of the oldest scientific institutions in the United States, the U. S. Naval Observatory has a rich and colorful history. Sky and Ocean Joined is essentially a story of the history of technology, in the form of telescopes, lenses, calculators, clocks and computers, over 170 years. It describes how this observatory has contributed to almost two centuries of unparalleled progress in astronomy. This volume will therefore appeal to historians of science and technology, astronomers and general readers interested in Naval history, navigation, timekeeping, positional astronomy, and celestial mechanics.
