They may not know it, but grocers face some of the most difficult questions in mathematics when stacking produce each day. Four centuries ago, the astronomer and mathematician Johannes Kepler guessed ...

When mathematicians solved a famed sphere-packing problem in 2005, one that first had been posed by renowned mathematician and astronomer Johannes Kepler in 1611, it made worldwide headlines. Now, two ...

In 1611 German mathematician Johannes Kepler made a conjecture about the densest way to stack oranges or other spheres with a minimum of space between them. It seemed nothing could beat the standard ...

Mathematicians have long known that it’s possible to pack at most 12 identical spheres around and touching a 13th. Dodecahedron. In 1943, Hungarian mathematician L. Fejes Tóth conjectured that the ...
