    en.wikipedia.org/wiki/Mathematics_of_paper_folding

    The napkin folding problem is the problem of whether a square or rectangle of paper can be folded so the perimeter of the flat figure is greater than that of the original square. The placement of a point on a curved fold in the pattern may require the solution of elliptic integrals.

  3. Geometry template - Wikipedia

    en.wikipedia.org/wiki/Geometry_template

    Stencil for the curves of y=x 2, y=tan(x), y=sin(x), and y= ⁠ 1 / 2 ⁠ sin(x). A geometry template is a piece of clear plastic with cut-out shapes for use in mathematics and other subjects in primary school through secondary school. It also has various measurements on its sides to be used like a ruler. In Australia, popular brands include ...

  6. Convection (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Convection_(Heat_transfer)

    Free or natural convection: when fluid motion is caused by buoyancy forces that result from the density variations due to variations of thermal ±temperature in the fluid. In the absence of an internal source, when the fluid is in contact with a hot surface, its molecules separate and scatter, causing the fluid to be less dense.

  7. Expression templates - Wikipedia

    en.wikipedia.org/wiki/Expression_templates

    Expression templates have been found especially useful by the authors of libraries for linear algebra, that is, for dealing with vectors and matrices of numbers. Among libraries employing expression template are Dlib, Armadillo, Blaze, [5] Blitz++, [6] Boost uBLAS, [7] Eigen, [8] POOMA, [9] Stan Math Library, [10] and xtensor. [11]

  8. Silhouette (clustering) - Wikipedia

    en.wikipedia.org/wiki/Silhouette_(clustering)

    A clustering with an average silhouette width of over 0.7 is considered to be "strong", a value over 0.5 "reasonable" and over 0.25 "weak", but with increasing dimensionality of the data, it becomes difficult to achieve such high values because of the curse of dimensionality, as the distances become more similar. [2] The silhouette score is ...
