Models can be divided into physical models (e.g. a ship model or a fashion model) and abstract models (e.g. a Numerical weather prediction, set of mathematical equations describing the workings of the atmosphere for the purpose of weather forecasting). Abstract or conceptual models are central to philosophy of science. In scholarly research and applied science, a model should not be confused with a theory: while a model seeks only to represent reality with the purpose of better understanding or predicting the world, a theory is more ambitious in that it claims to be an explanation of reality.

It replaced the Patowmack Canal, which shut down completely in 1828, and could operate during months in which the water level was too low for the former canal. The canal's principal cargo was coal from the Allegheny Mountains. Construction began in 1828 on the canal and ended in 1850 with the completion of a stretch to Cumberland, although the Baltimore and Ohio Railroad had already reached Cumberland in 1842. The canal had an elevation change of which required 74 canal locks, 11 aqueducts to cross major streams, more than 240 culverts to cross smaller streams, and the Paw Paw Tunnel. A planned section to the Ohio River in Pittsburgh was never built. The canal is now maintained as the Chesapeake and Ohio Canal National Historical Park, with a trail that follows ...
