Truncated Icosahedron: Maker Faire NYC Most Memorable for Kids

October 23, 2012Helene McLaughlin

While attending World Maker Faire in New York earlier this month, I was surrounded by hundreds of DIY projects that had been dreamt up by hackers and makers around the world. The projects were magnificent! From the moment I walked through the gates for set-up on Friday till we had to leave to drive home on Sunday, there was one display that I was magnetized to. From afar it imply looked like a large wooden sculpture of an soccer ball. I had to know more. I immediately went up and started taking pictures, it was massive and very impressive. The structure was a truncated icosahedron and I hadn’t even seen the best part of the sculpture at that point. Rob Marshall, owner of Hamlet Construction, had turned this ancient design into what he calls the “Happy Fun Ball.”

But I realize that I’m one of the lucky ones, girls who naturally like math, in and of itself. Not all girls are that lucky, however, and Danica McKellar writes books for those girls.

Geek Celebrates Hanukkah With Science: Day Eight

December 27, 2011December 13, 2017GeekMom1

It’s been another wonderful science-driven holiday season! We’ve experimented with balloons that blast-off, nearly unsinkable dinghies, delicious math candies, stackable liquids, desiccated dancers, split light, and put a minature Jaques Cousteau in a bottle.
