If your math teacher told you that mathematics is everywhere, believe him. Almost all the things that we see around (even things that we do not see) are related to mathematics — even potato chips. Yes, even potato chips.

Some potato chips, particularly Pringles (I hope they give me 500 bucks for this), are in a shape of a saddle. In mathematics a saddle-shaped graph is called a hyperbolic paraboloid (see left figure).

A hyperbolic paraboloid quadratic and doubly ruled surface given by the Cartesian equation . Now, whatever that means will be discussed when you take your analytic geometry course.

For now, let’s be happy that we know that even potato chips can be modeled by graphs. 🙂

Fantastic! As a math professor and textbook author, I love finding math in everyday life. Question, what program or plugin did you use to add the equations to your post? I’ve been looking for one to use on my blog but haven’t had any luck with the ones I’ve tried so far.

Hi Dr. Bittinger,

I am using Latex, but it’s not a plugin since it is integrated to WordPress.com (I am still using WordPress.com). If you are using WordPress.org, there is a Latex plugin, but I haven’t tried it yet. If you are using blogger, then this post might help you.

Have a blessed Holy week!
