Unfortunately, the volume of the dodecahedron formed by
unfolding a cube as in the University of Ghent animation above
is not double that of the cube, since refolding the cube leaves
an empty space inside … not shown in the Ghent animation.
But taking six congruent square pyramids that form a cube and using
them to cover the faces of a second, congruent, cube yields a
rhombic dodecahedron. This does offer a sort of solution to the
Delian problem… provided the new rhombic-dodecahedral altar is
found to be fit for ceremonial use. See . . .

George E. Weaver (1942-2015) Weaver was a philosophy professor at Bryn Mawr College before retiring in 2008. He had an interest in mathematics, among other fields, and taught discrete mathematics and mathematical logic at Bryn Mawr. A colleague said that Weaver "taught with passion and rigor, and cared deeply about his courses and the students. Students who studied with him had a deep respect and admiration for him." Weaver was an AMS member since 1972. Read more about his life in an obituary published in the Philadelphia Inquirer. |
Weaver reportedly died on December 4, 2015.
