I remember how I had passed my geometric origami lesson in university by just creating the shape you see below by paper years ago.

I am a bit surprised that now this object is everywhere including Youtube. In 1999, all we had a bunch of amateur geocities pages for such things. Anyway, this is called as five intersecting tetrahedra and can be done using origami techniques in a few hours without using any glues. The beauty of this just impressed my professor that he gladly gave me a pass mark even though I missed most of his lessons preferring laying under trees

Mathematics can be easily used as a language of beauty and charm. Bathseba Grossman uses her mathematics knowledge excellently by creating 3D sculptures which have geometrical and topological meaning using CAD systems and bronze. Maybe, you have already seen some Mobius strip or Klein bottle inspired objects which have simple dimension tricks. But, I am sure most people didn’t see or hear about the following structures. Here are a few of them :

Borromean Rings :

The connections between edges and surfaces are naturally appealing to us since it looks so organic and soft.

The Gyroid :

Another innovating object which uses the principles of minimal surfaces and repeat themselves in 3D.

Ora :

A complicated looking but actually simple double-tetrahedron. It is also playing with our symmetry obsession.

You can see lots of other sculptures at Bathseba Grossman website and read the mathematical explanations if you are further interested in the subject.
