Induction

Hannah has another loose tooth, her third. In the car the other morning she took a break from wiggling it to inform me that "When this tooth comes out, the Tooth Fairy is going to bring me $2!"

Really? How do you know that?

"Well, when I lost my first tooth, I got 2 quarters. Then when I lost my next tooth, I got a dollar bill. Every time I loose a tooth, I get twice the amount of of money I got for the last tooth. So I'm getting $2 for this tooth."

I almost almost asked her how much she figured she'd get after she lost her, say, 12th tooth. But I don't think I want her counting that far ahead (though I was curious whether she could figure it out--she keeps surprising me with her intuitive grasp of arithmetic).

What she doesn't know is that the Tooth Fairy grabbed that dollar bill in a panic when she remembered--on her way to go wake Hannah up for school--that she hadn't taken care of the tooth the night before.

Heat Wave

I don't know if we're supposed to call it a heat wave if it's just one day, but it was really, really unexpectedly and unseasonably warm today. This time last week, we were complaining about how it is May and we are still wearing fleece jackets and heating the house. According to the thermometer on the side of our house, it was 87.6 degrees (F) here. Or, as Hannah put it as she begged for something cold to eat (read: a popsicle), "as hot as the surface of the sun".

Pedant that I am, I took this as an opportunity to talk about how hot the surface of the sun really is (that'll teach her to exaggerate!). I nearly went and looked up exact approximations in the encyclopedia, but, well, it was too hot out and a popsicle was sounding mighty fine.

This did remind me of an episode from back when I was a TA in a Physics For People Who Hate Math But Want To Be Able To Tell Their Friends They Are Studying Physics class. The instructor was talking, in very general terms, about how hot the surface of the sun is and the irritating, wannabe-know-it-all in the front row, furiously scribbling notes--you know the one--raised her hand and asked: "Is that Fahrenheit or Celsius?". The instructor, bless his long-suffering heart, gritted his teeth and told her it didn't matter, really, we are talking about THOUSANDS AND THOUSANDS OF DEGREES HERE! I only wish he had let me field that question, because I would have thrown down my piece of chalk for dramatic effect.

Word Problem

A charming, somewhat older, fellow and his trophy wife each celebrated a birthday within the last week. If the husband's age is 200% that of the wife's and together they will reach a century in five years' time, how old are they now?
