On this day in history...

On November 2, 1815, George Boole was born, the English mathematician from whom we got Boolean operators. I teach Boolean operators by elaborating on this joke that I read somewhere in my first semester of library school:

If you send a librarian (or a database, as I tell students) to the store with a shopping list for sugar and flour and butter and chocolate chips, the librarian (or the database) will come back from the store with a cookie.

Sure, it's a nerdy joke, but it's a good jumping-off point and involves lots of pictures of delicious baked goods (flour AND chocolate = brownies, chocolate cake, chocolate chip cookies, chocolate croissants). I find this particularly effective when the class is right before dinner.

So, thank you, George Boole, and happy birthday! Read more about him here.


  1. Love this post. You are such a good librarian!

  2. But if

    $Mouse = "A Cookie"
    $Moose = "A Muffin"



    A great trivia factoid!

  3. Zackie, that was perhaps the greatest blog comment ever posted. Thank you.
