Here’s a project we did a long time ago in collaboration with Vi Hart, that somehow never made it into Math Mondays. The idea is simple: lay out pennies on a large horizontal surface, such as a floor, in the pattern of a Sierpinski triangle. How many? Well, the basic triangle with a one-penny size hole
A detailed, step-by-step illustration of how to make a tensegrity structure that you may not find in a lot of other places — a frustum of a pentagonal pyramid.
Sculptor George W. Hart recently designed and constructed two five-fold symmetrical sculptures with his “Crystal Flowers in Halls of Mirrors: Mathematics Meets Art and Architecture” class at Aalto University in Helsinki.
For the Museum of Mathematics Last column, we saw some of the basics of modular origami with the Sonobe unit. Today’s post is mostly a gallery of a few of the limitless cool things you can do with this unit. But first, a note about chirality. A three-dimensional object is chiral if it cannot be […]
One way to remember the first few digits of pi is to count the letters in the words of this phrase…
Create awesome, sweet Escher cookies using 3D printed rollers with MC Escher art on them.
This is the final installment in our epic Math Monday series on the intricate world of mechanical linkages. See the Linkages series introduction for the MoMath Linkage Kit, an introduction, and general instructions.
