*, and decided that it could entertain us today in the math blog. After all, geometry is clearly math. There were several very positive book reviews on Amazon, and one disgruntled review entitled "*

**Geometry of Pasta***Another reason to hate geometry.*"

The reviewer goes on to say,

*"I was hoping for ... a book that would teach me about the various pastas and how to use them ... the graphic images are artsy, but useless. They are black and white ... look like art deco wallpaper or bed sheets".*

Here's a sample. What do you think?

You can take a look at all of the pasta shapes here.

Being a writer and editor, I enjoy reading book reviews, and I think it's fair for a reader to be irritated by images of an item if they don't help connect what an item is (

*identity / name*) to what it looks like (

*appearance / shape*) and what you can do with it (

*utility / cooking*).

If, like me, you grew up without Italian relatives or friends, you may not understand pasta from these pictures. I moved to the page with an alphabetical list of pasta and clicked on

*. It turns out to be a twisted worm-like shape marked 180 x 10 that's good with*

**BUSIATI***Pesto Genovese*. I think

*pesto*is a green sauce and

*Genoa*is an Italian town, but I've never had a basic pasta course, and these references baffle me.

(

*Yes, you are correct. I cannot successfully order pasta in an Italian restaurant.*)
