Update to page 243 of Sacred Geometry Design Sourcebook
Note: This update only applies if you a copy of Sacred Geometry Design Sourcebook that was printed before about 1999; check page 243 and look for the volume of the Snub Dodecahedron; if you don’t see: “37.61665″, then copy the graphic above and paste it over the corresponding section on page 243 to provide more accuracy.
A number of years ago, realizing that I needed a few more digits to complete the desired 6-decimal place accuracy for a few of the more complicated archimedeans (particularly the snub dodecahedron), I held a book give-away contest to the first person who could provide the missing digits of accuracy, and show how these were derived. Johan of Delfgauw, Netherlands, was the contest winner (a true math enthusiast and a a student of Industrial Design Engineering at the Technical University of Delft. Johan won a free copy of my Sacred Geometry Design Sourcebook.
