  2. Naismith's rule - Wikipedia

    That is, 7.92 units of distance are equivalent to 1 unit of climb. For convenience an 8 to 1 rule can be used. So, for example, if a route is 20 kilometres (12 mi) with 1600 metres of climb (as is the case on leg 1 of the Bob Graham Round, Keswick to Threlkeld), the equivalent flat distance of this route is 20+(1.6×8)=32.8 kilometres (20.4 mi ...

  3. Galileo's law of odd numbers - Wikipedia

    en.wikipedia.org/wiki/Galileo's_law_of_odd_numbers

    Distance covered is the area under the line. Each time interval is coloured differently. The distance covered in the second and subsequent intervals is the area of its trapezium, which can be subdivided into triangles as shown. As each triangle has the same base and height, they have the same area as the triangle in the first interval.

  4. Isle of Lewis - Wikipedia

    en.wikipedia.org/wiki/Isle_of_Lewis

    One of the possible routes, between Stornoway and Ullapool, would be over 50 miles (80 km) long and hence the longest road tunnel in the world; [36] [37] however, shorter routes would be possible. Stornoway is the public transport hub of Lewis, with bus services to Point, Ness, Back and Tolsta, Uig, the West Side, Lochs and Tarbert, Harris ...

  5. Distance geometry - Wikipedia

    en.wikipedia.org/wiki/Distance_geometry

    Distance geometry is the branch of mathematics concerned with characterizing and studying sets of points based only on given values of the distances between pairs of points. [1] [2] [3] More abstractly, it is the study of semimetric spaces and the isometric transformations between them.

  6. Distance from a point to a line - Wikipedia

    en.wikipedia.org/wiki/Distance_from_a_point_to_a...

    The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.

  7. History of the Outer Hebrides - Wikipedia

    en.wikipedia.org/wiki/History_of_the_Outer_Hebrides

    The earliest written mention of the Outer Hebrides was by the Greek historian Diodorus Siculus in 55 BC. He wrote that there was an island called Hyperborea (which means "Far to the North") where a round temple stood from which the moon appeared only a little distance above the earth every 19 years, an apparent reference to the stone circle at Callanish.

  8. Möller–Trumbore intersection algorithm - Wikipedia

    en.wikipedia.org/wiki/Möller–Trumbore...

    The Möller–Trumbore ray-triangle intersection algorithm, named after its inventors Tomas Möller and Ben Trumbore, is a fast method for calculating the intersection of a ray and a triangle in three dimensions without needing precomputation of the plane equation of the plane containing the triangle. [1]

  9. Heron's formula - Wikipedia

    en.wikipedia.org/wiki/Heron's_formula

    In this example, the triangle's side lengths and area are integers, making it a Heronian triangle. However, Heron's formula works equally well when the side lengths are real numbers. As long as they obey the strict triangle inequality, they define a triangle in the Euclidean plane whose area is a positive real number.
