Geocentric model work, the "Almagest", was the culmination of centuries of work by Hellenic, Hellenistic and Babylonian astronomers. For over a millennium European and Islamic astronomers assumed it was the correct cosmological model. Because of its influence, people sometimes wrongly think the Ptolemaic system is identical with the geocentric model. Ptolemy argued that the Earth was a sphere in the center of the universe, from the simple observation that half the stars were above the horizon and half were below the horizon at any time (stars on rotating stellar sphere), and the assumption that the stars were all at some modest distance
Central House (Central, Alaska) Central House (Central, Alaska) The Central House, also known as Erickson & Stade's, at Mile 128 on the Steese Highway in Central, Alaska, was a log structure built in 1926 by Riley Erickson and John Stade, replacing an 1894 log and sod structure that was burned in a 1925 fire. It served as a roadhouse restaurant and hotel, and was listed on the National Register of Historic Places in 1978. Located on Crooked Creek, it was deemed significant for its historical role as a central focus for miners of other creeks that were Birch Creek tributaries and for serving travelers.
