boxofdelightsSnow! and lots of it! PSD schools were closed today and yesterday. Unfortunately, CSU didn't close until the afternoon, so I had to drive Nixie to her math class. There was a quiz, and Nixie isn't doing well enough to skip it.
The math class -- it's basically the second half of Thomas's Calculus -- is surprisingly difficult. Not because of the material. After the lecture on partial differentials Nixie said she had paid attention, but still didn't understand what they were. So I got a vase and a marker, and drew parallel lines on the vase from base to lip. "This is y=0. y=1. y=2." Then I took a toothpick and surfed it up and down one of the lines. "The partial differential with respect to x gives us information about how x changes while we hold y constant." I put down the toothpick, picked up the marker, and started drawing circles around the vase. "This is x=0."
"Okay, I get it," said Nixie. She glared at how obvious it was. "She's such a bad teacher!"
"No," I said, "I'm such a good one." But I think Nixie is right. Her teacher is really not good at teaching.
About the house: I thought I could have at least a virtual housewarming party this weekend, but no. The plasterer will probably be done sometime next week, and then I can move in. This weekend, I am using Samhain's energy to finish things at this house.
