    Square + Circle = Squircle.

    Piet Hein -> SuperEllipse ->Sergels Torg design.
    Superellipse is also known as Lamé curve, after Gabriel Lamé

    Super ellipses.
    Hein advocated the use of Lame curves in various aspects, including city planning.

    Super-ellipse is the connect. Pic 1 (Gabriel Lamé who generalized the equation for the ellipse), pic 2 (Piet Hein, who is often credited with super-ellipse invention),pic 3(Sergels Torg, Stockholm, Sweden was a design challenge won by Piet Hein . His proposal was based on a superellipse with n = 2.5 and a/b = 6/5.)

    Connection is “superellipse”

    1. Gabirel Lame – created The general Cartesian notation of the superellipse, he generalised the equation for ellipse

    2. Piet Hein, who created the superellipse which became the hallmark of modern Scandinavian architecture.

    3. sergels torg, stockholm – The superellipse-shaped fountain and the rectangular black-and-white composition.

    Superellipse – invented by Gabriel Lame. Piet Hein often gets credited for inventing it. He actually proposed it as an intermediate between straight lines and circles in architecture. Third visual is the city square Sergels torg which uses the shape.

    gabriel lame and piet hein 3rd pic is the Sergels torg in sweden….connect is the superellipse… The general Cartesian notation of the form comes from the French mathematician Gabriel Lamé (1795–1870) who generalized the equation for the ellipse.
    Though he is often credited with its invention, the Danish poet and scientist Piet Hein (1905–1996) did not discover the super-ellipse. In 1959, city planners in Stockholm, Sweden announced a design challenge for a roundabout in their city square Sergels Torg. Piet Hein’s winning proposal was based on a superellipse with n = 2.5 and a/b = 6/5.
