Today our math and 3d printing project combined ideas from two great books. First Matt Parker’s book **Things to Make and Do in the Fourth Dimension **and Henry Segerman’s book Visualizing Mathematics with 3D Printing

We started out the project today by watching Parker’s fun video about 4 dimensional platonic solids:

Next we look at some of the 3d prints we have of projections of the four dimensional platonic solids from Segerman’s book. Here’s what the boys had to say:

Then we went through some of the shapes in more detail. Here’s the 5-cell

Here’s what the boys thought about the two different versions of the hypercube that we have.

I’d add that our Zome version of Bathsheba Grossman’s “Hypercube B” blew me away, too:

Finally, we talked about the 24-cell and the 120-cell. Sorry this part went a little long, but the shapes are really cool!

I’m loving 3d printing more and more every day. The opportunities to take ideas from books and videos and put them directly into the hands of kids is just amazing. Thanks to Parker and Segerman for doing the heavy lifting for me on this project!
