A **simple polytope** is a type of polytope characterized by certain geometric properties. Specifically, it is defined as a convex polytope in which every face is a simplex. In more technical terms, a polytope is called simple if at each vertex, exactly \(d\) edges (where \(d\) is the dimension of the polytope) meet.

The Board of Longitude was a British governmental body established in the 18th century to address the challenging problem of determining a ship's longitude at sea, which was essential for safe and accurate navigation. The board was created in response to the significant loss of ships and lives due to navigational errors, particularly in relation to the longitude problem.

In geography, a meridian is an imaginary line that runs from the North Pole to the South Pole, passing through the Earth's surface. Meridians are used to define longitude, which is a measure of how far east or west a point is from the Prime Meridian, which is designated at 0 degrees longitude. Each meridian is measured in degrees, with values ranging from 0° at the Prime Meridian to 180° east or west.

Principal meridians are the reference lines used in the Public Land Survey System (PLSS) for surveying and mapping land in the United States. In Alaska, the principal meridian is the **Copper River Meridien**. This meridian serves as the basis for surveying land in the areas that were established under the PLSS in Alaska. Additionally, it's worth noting that Alaska has a unique surveying system due to its vast size and diverse geography, which includes several other linear systems and regional adjustments.
