Summary

Description
English: Johannes Kepler discovered that the tetrahedron can be inscribed in the cube, occupying four of the cube's eight corners, with its edges as the diagonals of the six square faces. His drawing of the relationship between the two solids appears on page 181 of book V of his 'Harmonics of the World', published in 1619.
