Last night at dinner I was opening a small spherical glass container of mustard, and my husband and I got into a discussion on whether it was a jar or a bottle. Then we started thinking of other glass containers and tried to sort them into the jar and bottle camps. Yes, I know, scintillating. Tonight maybe we'll discuss pennies: pros and cons.
Of course then I started thinking of geometry when we hit the unit of being precise with definitions of triangles and squares and such. I looked up the jar/bottle definitions via google, and I'm not completely impressed with the output. The word "wide" is used, and I think that's subjective. And the jury is still out on the mustard bar/jottle.
