Mending, working, getting amped

My eye appears to be healing up nicely, thanks to the drops I picked up before work yesterday. Slept well this morning and have only noticed the irritation a few times throughout the day. (Like now, when I'm writing about it. Typical.)

The curvaceous and bubbly elisem came over to conspire with Ericka over the creation of useful things for Elise's presence at conventions and craft shows and the like. I dropped her off at Mike's after they'd had enough play time and continued down to Chez minnehaha to pick up a ticket to tomorrow's rally for John Kerry here in Minneapolis.

Chatted briefly with K and headed home to prep for work. Prepping for work involves food and napping. It also involved, today, watching an episode of "Nova" on PBS regarding a manuscript by Archimedes that had been discovered. It was a not-often-copied manuscript of the Greek mathematician's that had been made into a palimpsest. That is, the pages of the original had been scraped clean of their ink and re-used for a later book. (In this case, a medieval prayer book.)

The most fascinating portion of the program for me was the method of approximating the value of pi that Archimedes worked out. Very accurate and intuitive; it basically involves setting the highest and lowest values possible for a circle's circumference by inscribing polygons inside the circle and surrounding the same circle with other polygons. That is, if you draw a triangle inside a circle, the circumference of the circle must be larger than the length of the sides of the triangle. Similarly if you draw a hexagon around a circle, the circumference must be less than the length of the sides of the hexagon. (Draw this out for yourself if you don't get it from my description. It looks quite intuitive visually.) By making polygons with progressively more sides (Archimedes went up to 96) you get closer and closer to the real value of the circumference. Since pi is the ratio of the circumference of a circle to its diameter, this gets you closer and closer to pi. Archimedes came up with the approximation of 3.14, a number no doubt familiar to anyone that's graduated from high school.

Work is slow tonight, which is good as I'm filling in for my lead again. My stalwart leadership means more free time for everyone! This gives me plenty of time to get pumped up for the Kerry rally tomorrow. I'm quite excited; it'll be my first political rally.

The long, dark tea time

There's something about 5:00 a.m. on a slow night at work. Nothing to work on (though we expect a flurry soon) and so my thoughts wander like the clicking of mouse. Many times, I feel as if I'm wasting away here; not progressing toward anything, just making do. That, of course, is what this job was nearly three years ago when I picked it up. Something to pay the bills after being fired.

I need to find more ways to enrich my spirit so that I make it through these times easily. I am, for example, still pumped about attending the Kerry rally later today. I'm actually looking forward to finding counter-protesters and seeing if they can be engaged in an intellectual discussion of the issues. Hmm. Better bone up at http://www.spinsanity.org and http://www.factcheck.org before I start something like that.
