Hamann-Todd Collection
The Cleveland Museum of Natural History is a natural history museum located approximately five miles (8 km) east of downtown Cleveland, Ohio in University Circle, a 550-acre (220 ha) concentration of educational, cultural and medical institutions. The museum was established in 1920 by Cyrus S. Eaton to perform research, education and development of collections in the fields of anthropology, archaeology, astronomy, botany, geology, paleontology, wildlife biology, and zoology. The museum traces its roots to the Ark, formed in 1836 on Cleveland's Public Square by William Case, the Academy of Natural Science formed by William Case and Jared Potter Kirtland, and the Kirtland Society of Natural History, founded in 1869 and reinvigorated in 1922 by the trustees of the Cleveland Museum of Natural History. Donald Johanson was the curator of the museum when he discovered " Lucy," the skeletal remains of the ancient hominid '' Australopithecus afarensis''. The current Curator ...

Cleveland
Cleveland ( ), officially the City of Cleveland, is a city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located in the northeastern part of the state, it is situated along the southern shore of Lake Erie, across the U.S. maritime border with Canada, northeast of Cincinnati, northeast of Columbus, and approximately west of Pennsylvania. The largest city on Lake Erie and one of the major cities of the Great Lakes region, Cleveland ranks as the 54th-largest city in the U.S. with a 2020 population of 372,624. The city anchors both the Greater Cleveland metropolitan statistical area (MSA) and the larger Cleveland–Akron–Canton combined statistical area (CSA). The CSA is the most populous in Ohio and the 17th largest in the country, with a population of 3.63 million in 2020, while the MSA ranks as 34th largest at 2.09 million.

Lucy (Australopithecus)
AL 288-1, commonly known as Lucy, is a collection of several hundred pieces of fossilized bone representing 40 percent of a female of the hominin species ''Australopithecus afarensis''. In Ethiopia, the assembly is also known as (ድንቅ ነሽ), which means "you are marvelous" in Amharic. Lucy was discovered in 1974 in Africa, at Hadar, a site in the Awash Valley of the Afar Triangle in Ethiopia, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History. The Lucy specimen is an early australopithecine and is dated to about 3.2 million years ago. The skeleton presents a small skull akin to that of non-hominin apes, plus evidence of a walking-gait that was bipedal and upright, akin to that of humans (and other hominins); this combination supports the view of human evolution that bipedalism preceded increase in brain size. A 2016 study proposes that ''Australopithecus afarensis'' was also to a large extent tree-dwelling, though the extent of this is ...

Haplocanthosaurus
''Haplocanthosaurus'' (meaning "simple spined lizard") is a genus of intermediate sauropod dinosaur. Two species, ''H. delfsi'' and ''H. priscus'', are known from incomplete fossil skeletons. It lived during the late Jurassic period (Kimmeridgian stage), 155 to 152 million years ago.Turner, C.E. and Peterson, F., (1999). "Biostratigraphy of dinosaurs in the Upper Jurassic Morrison Formation of the Western Interior, U.S.A." Pp. 77–114 in Gillette, D.D. (ed.), ''Vertebrate Paleontology in Utah''. Utah Geological Survey Miscellaneous Publication 99-1. The type species is ''H. priscus'', and the referred species ''H. delfsi'' was discovered by a young college student named Edwin Delfs in Colorado, United States. ''Haplocanthosaurus'' specimens have been found in the very lowest layer of the Morrison Formation, along with ''Hesperosaurus mjosi'', ''Brontosaurus yahnahpin'', and ''Allosaurus jimmadensi, Allosaurus jimmadseni''.Foster, J.

Cleveland Public Library
Cleveland Public Library, located in Cleveland, Ohio, operates the Main Library on Superior Avenue in downtown Cleveland, 27 branches throughout the city, a mobile library, a Public Administration Library in City Hall, and the Ohio Library for the Blind and Physically Disabled. The library replaced the State Library of Ohio as the location for the Ohio Center for the Book in 2003. History Founding In 1811, the idea behind the Cleveland Public Library came "out of small beginnings" when sixteen of Cleveland's sixty-four residents subscribed to its first library, established to distribute the rare printed book. The members read books such as the history of Rome, ''Lives of the English Poets'', Goldsmith's ''Greece'', and ''Don Quixote''. In 1867, thCleveland an [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astrolabe
An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since c. 206 BC),Li Shu-hua, p. 176 and later adopted for navigation by the Song Dynasty Chinese during the 11th centur ...

Measuring Instrument
A measuring instrument is a device to measure a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty. These instruments may range from simple objects such as rulers and stopwatches to electron microscopes and particle accelerators. Virtual instrumentation is widely used in the development of modern measuring instruments. Time In the past, a common time measuring instrument was the sundial. Today, the usual measuring instrum ...

Planetarium
A planetarium ( planetariums or ''planetaria'') is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate their motion. The projection can be created in various ways, such as a star ball, slide projector, video, fulldome projector systems, and lasers. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth. Planetaria range in size from the 37 meter dome in St. Petersburg, Russia (called “Planetarium No 1”) to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
