This is a category about a place or building that is listed on the National Register of Historic Places in the United States of America. (It also shows an outline of what was the angled Upper Water Street on the grounds of the National Academy of Sciences) - (lightly edited from remarks by User:Clindberg, originally made at User talk:Jmabel/Stereo cards of Washington, D.C.) It's near the Kennedy Center, and Google Maps still points out the "Old Naval Observatory". 23rd street is still there, but the rest of the rectangular street grid is gone. By 1900, Upper Water Street had been extended along the old shoreline so it became the southern boundary, but the entire area south was being landfilled (eventually used for the Lincoln Memorial). (24th street ended at E street, with the Observatory driveway on the other side.) The Potomac river side is roughly equivalent to C street, but is angled (higher than C street on 25th street side, but below it on 23rd, such that there was an Upper Water Street below C, but that was it). Looking at a map showing what 1860 Washington looked like, it was located on a tract bounded by E street on the north, 23rd street on the east, 25th street on the west, and the Potomac River on the south. Gilliss Library holds one of the most complete collections of.
Department of Defense and a standard of time for the entire United States. The building still exists, but it's part of a much larger complex, the Bureau of Medicine and Surgery. The United States Naval Observatory (USNO) provides a wide range of astronomical data and products, and serves as the official source of time for the U.S. Their most used social media is StumbleUpon with about 91 of all user votes and reposts. We found that English is the preferred language on Tycho Usno pages. Perhaps most essential to the study of the history of science is the scientific periodicals collection, originating from across the globe and dating from the early 17th century to today.English: Old Naval Observatory. is a web project, safe and generally suitable for all ages. The 800-volume rare book collection, dating from 1482 to 1799, consists of the foundational texts in the history of astronomy, and our larger 19th-century scientific monograph collection is ripe for study. Hundreds of manuscript observation notebooks, detailing the nightly observations of astronomers since the mid-19th century, are available for research, as are the notebooks from the several 19th-century Transit of Venus expeditions organized by the Naval Observatory to such far-flung locations as Vladivostok and Santa Cruz.
Scientific instruments, however, are only a small part of the collection. Researchers will be able to see the historic scientific instruments they study still in use, like the 26-inch refractor telescope which was used by USNO staff astronomer Asaph Hall for the discovery of the Moons of Mars in 1877. The USNO Library’s unique environment makes it an exceptional place for the study of the history of science. These resources can and should facilitate investigations into the dramatic changes in the fields of astronomy and physics, particularly in the 19th and 20th century. As one of the most complete astronomical collections in the country, the USNO Library has important resources for the investigation into the history of science and technology.
Since its founding in 1841, the US Naval Observatory has amassed culturally and scientifically significant materials relevant to the study of the intellectual, social and cultural history of the United States and beyond.
