#### Nonplanar Geometries

I’ve been reading up a bit on nonplanar geometry recently.

The geometry with which most of us are familiar is planar geometry, described by the great Greek mathematician Euclid. 636 more words

#### First Friday Poem

**Euclid**

Old Euclid drew a circle

On a sand-beach long ago.

He bounded and enclosed it

With angles thus and so.

His set of solemn greybeards… 34 more words
