River Lune Weasdale Beck (5.58 km = 3½ mls) at 1.6 miles from the well. Weasdale Beck is the uppermost headwater of River Lune recorded in Environment Agency's Catchment Data Explorer. It then passes the remnants of a Roman fort near Low Borrowbridge at the foot of Borrowdale, and flows through south Cumbria, meeting the Irish Sea at Plover Scar near Lancaster, after a total journey of about . The valley of the Lune has three parts. The northern part between its source and Tebay is called Lunesdale. Below this is the spectacular Lune Gorge through which both the M6 motorway and
Lune of Hippocrates give the only constructible squarable lunes; in particular, there are no constructible squarable convex lunes. Lune of Hippocrates In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically. Hippocrates wanted to solve the classic problem of squaring the circle, i.e. constructing
