Apologies for absence

My computer has been acting up recently, freezing and going blank and so on. Michael vowed to fix it, saying "Your computer is less reliable than a windows box."

He upgraded it, and then took it apart to see what might be wrong. It was mostly fine, although one memory card wasn't seated properly, the fan was completely coated in dust. The real problem came in disconnecting the keyboard cable: Michael managed to snap a piece of plastic off the connector.

First he tried to fix it using electrical tape, a piece of kleenex, and a small piece of wood. That didn't work, and so he tried a piece of tagboard, which did work. The keyboard is slightly curved in the middle from the pressure of the cardboard, which I suppose might be more ergonomic =).

This will work for the time being, but we're still looking for a great deal for a new laptop.

A day at the fair

Yesterday afternoon the whole family went to the NC state fair. We had a good enough time that I think we are going back next year, although perhaps we will leave Luke at home with a sitter. We went right after Eleanor's school. Michael picked up Eleanor, I drove Luke and Amanda. Through an amazing bit of timing, we met in the parking lot and walked to the fair together, about a 10 minute walk (not bad at all, really). I had meant to get to the fair much earlier and see the parts that Eleanor and Michael claimed not to be interested in (the animals and crafts, mostly) but I was running a little late. Our area has been in a serious drought for the past few months, so I am not complaining that it rained (hard) on us as we were getting to the gate. But it does seem a bit hard that we planned to go to the fair on the one day in the past 3 months that we had a rainstorm. Fortunately, the rain was scattered, and the clouds soon moved off to water another area. We took the opportun...

Books I like: magic/science fiction

I read a lot of science fiction and fantasy when I was younger, so I was surprised when I was thinking about this list at how few books were on it. The other thing that is interesting is how many books I just remember a few details from, but not anything useful like a title or author. Half Magic and the whole series, by Edward Eager: My favorite is Knight's Castle, although I suspect I would have enjoyed it more if I had ever read Ivanhoe... Mrs. Piggle Wiggle by Betty MacDonald: I'm not sure when it happened, but I now identify with the parents rather than the kids. The Seven Citadels by Geraldine Harris: I came back to the Jr. High library to check this out even after I moved on to the high school. Girl with the Silver Eyes by Wilo Davis Roberts: I always wondered what would happen if I had ESP and other "special" abilities. The OZ books, by L. Frank Baum: I read almost all of these (all the ones I could find in the library, rather). My favorite is Tik - To...

Why you should study the history of math

Why you should study the history of math In the mid 1300s a fad made its way around Italy. Mathematicians would challenge each other to “mathematical duels”. They would post problems for their opponents to solve, sometimes along with their solutions in coded poetry. The winners would get support and funding from rich patrons, the losers would descend into obscurity. One such contest, between Fiore and Tartaglia, involved a new method for solving the cubic. In order to win, Tartaglia worked day and night to find Fiore’s method---unfortunately, Fiore did not do the same and only knew his own method and no others. (*Recall that the formula for solutions to quadratic equations of the form use the quadratic formula, Giorlamo Cardano---physician, philosopher, astrologer and mathematician---convinced Tartaglia to share his method and promised never to reveal it. Then Cardano figured out a more general method, and wanted to share it, but was blocked by his promises. Fortunately (for Ca...
