Stuff We'll Never Ever Need

I used to have a MySpace account.  I started my blog there.  But after I had a few too many technical difficulties, I moved the blog here.  I have since closed the MySpace account.  I hate to lose all of my blogs from that time, so from time to time I repost them here. 

This one was originally posted on July 2, 2007.  I think it's apropos as I'm about to make another batch of these cookies (in a day or two).    

I am planning on baking some chocolate chip cookies.  (You know which recipe.)  It was suggested to me that to streamline this time-consuming activity that I should do the pan cookie variation.  I thought that this was a good idea, so I looked into it.

The recipe calls for a 10 x 15 inch jelly roll pan.  First I had to figure out what a jelly roll pan was.  Once I realized that I had one I measured it.  It's 12 x 17 inches.  And this is where the math came in.

Okay, so first thing: I double the recipe.  That means that this will fill two 10 x 15 inch jelly roll pans.  So, the recipe fills an area of (10 x 15 = 150) 150 square inches.  Double that--300 square inches.  My pan has an area of (12 x 17 = 204) 204 square inches.  So, too big for a single batch, not quite big enough for a double batch.  What to do now?

I went searching for a smaller pan to make up the difference.  I had a small cake pan, but that would only give me 45 square inches more.  300 - 204 = 96.  That was not quite half.  And then I found the pie pans.  Oops.  Now I have to remember the area formula for circles (actually, not an issue--I just hate bringing pi into the equation).

Right, so the pie pans give me roughly 33 square inches (not an exact figure because of the previously mentioned pi).  I have several, so three should do the trick (or at least make it close enough).

Sigh.  Baking should not be this complicated.

I sub for math classes a lot.  And someone always complains: "We'll never need to use this stuff."  I have told them otherwise, but they don't believe me.  I've given up the argument.  But they are wrong.
