  2. Sphere packing - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing

    The sphere packing problem is the three-dimensional version of a class of ball-packing problems in arbitrary dimensions. In two dimensions, the equivalent problem is packing circles on a plane. In one dimension it is packing line segments into a linear universe. [10]

    en.wikipedia.org/wiki/Packing_problems

    Packing identical rectangles in a rectangle: The problem of packing multiple instances of a single rectangle of size (l,w), allowing for 90° rotation, in a bigger rectangle of size (L,W) has some applications such as loading of boxes on pallets and, specifically, woodpulp stowage. For example, it is possible to pack 147 rectangles of size (137 ...

  4. Finite sphere packing - Wikipedia

    en.wikipedia.org/wiki/Finite_sphere_packing

    An arrangement in which the midpoint of all the spheres lie on a single straight line is called a sausage packing, as the convex hull has a sausage-like shape.An approximate example in real life is the packing of tennis balls in a tube, though the ends must be rounded for the tube to coincide with the actual convex hull.

  5. Sphere packing in a sphere - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing_in_a_sphere

    Sphere packing in a sphere is a three-dimensional packing problem with the objective of packing a given number of equal spheres inside a unit sphere. It is the three-dimensional equivalent of the circle packing in a circle problem in two dimensions.

  6. Tammes problem - Wikipedia

    en.wikipedia.org/wiki/Tammes_problem

    In geometry, the Tammes problem is a problem in packing a given number of points on the surface of a sphere such that the minimum distance between points is maximized. It is named after the Dutch botanist Pieter Merkus Lambertus Tammes (the nephew of pioneering botanist Jantina Tammes ) who posed the problem in his 1930 doctoral dissertation on ...

  7. Hilbert's eighteenth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_eighteenth_problem

    Hilbert's eighteenth problem is one of the 23 Hilbert problems set out in a celebrated list compiled in 1900 by mathematician David Hilbert. It asks three separate questions about lattices and sphere packing in Euclidean space. [1]

  8. Kissing number - Wikipedia

    en.wikipedia.org/wiki/Kissing_number

    For a given sphere packing (arrangement of spheres) in a given space, a kissing number can also be defined for each individual sphere as the number of spheres it touches. For a lattice packing the kissing number is the same for every sphere, but for an arbitrary sphere packing the kissing number may vary from one sphere to another.

  9. Sphere packing in a cube - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing_in_a_cube

    It is the three-dimensional equivalent of the circle packing in a square problem in two dimensions. The problem consists of determining the optimal packing of a given number of spheres inside the cube. Gensane [1] traces the origin of the problem to work of J. Schaer in the mid-1960s. [2]
