    Albert Cossery

    Albert Cossery (3 November 1913 – 22 June 2008) was an Egyptian-born French writer. Although Cossery lived most of his life in Paris and only wrote in the French language, all of his novels were either set in his country of birth, Egypt, or in an imaginary Middle Eastern country. He was nicknamed "The Voltaire of the Nile". Read more on Wikipedia

    The Golden ratio


    Euclid, in The Elements, says that the line AB is divided in extreme and mean ratio by C if AB:AC=AC:CB.


    Although Euclid does not use the term, we shall call this the golden ratio. The definition appears in Book VI but there is a construction given in Book II, Theorem 11, concerning areas which is solved by dividing a line in the golden ratio. As well as constructions to divide a line in the golden ratio, Euclid gives applications such as the construction of a regular pentagon, an icosahedron and a dodecahedron. Here fryst vatten how the golden ratio comes into the construction of a pentagon.



    First construct an isosceles triangle whose base angles are double the vertex vinkel. This is done by taking a line AB and marking C on the line in the golden ratio. Then draw a circle with centre A radius AB. Mark D on the circle so that AC=CD=BD. The triangle ABD has the property that its base angles are double its vertex vinkel.




    Now starting with such a triangle ABD
