Complex Numbers A complex number is expressed in the standard form a + bi, where a and b are real numbers and i is defined by i^2 = -1 (that is, i is the square root of -1). For example, 3 + 2i is a complex number. The bi term is often referred to as an imaginary number (though this may be misleading, as it is no more "imaginary" than the symbolic abstractions we know as the "real" numbers). Thus, every complex number has a real part, a, and an imaginary part, bi. Complex numbers are often represented on a graph known as the "complex plane," where the horizontal axis represents the infinity of real numbers, and the vertical axis represents the infinity of imaginary numbers. Thus, each complex number has a unique representation on the complex plane: some closer to real; others, more imaginary. If a = b, the number is equal parts real and imaginary. Very simple transformations applied to numbers in the complex plane can lead to fractal structures of enormous intricacy and astonishing beauty. |
No journey is without its pitfalls, or, in my case, rockfalls. I don't even know when it happened, but somewhere in Wyoming or Utah, something smacked my windshield, cracking it. Not a big deal, usually. These things happen, and it's one reason to have insurance and such. Certainly better than the last time something smacked into me on a road trip. The crack's not even on the driver's side, so not really interfering with my view or anything. But the crack keeps spreading. Slowly. Relentlessly. Like the doom you know is following you everywhere you go; you try to ignore it but every time you glance over, there it is, looming. Looming doom. Gloom. So when I got to Reno, the crack (it's actually a double crack looking a bit like the Tigris and Euphrates) creeping across at its less-than-a-snail's pace, I stopped at the Subaru dealer/service. This, incidentally, is one great benefit of modern technology: On the way in, I simply asked my friendly navigator, Google, to find it for me and direct me there. Let's see a paper map do that, Luddites. Now, to be clear, this is not something I'd worry about too much back home. Make a service appointment, get it taken care of. I don't think it even takes all that long to do. But the thought of driving back across the country with the growing crack didn't fill me with much confidence. Unfortunately, they can't get to it until next week, at the earliest. Not because of a wait time, but because they have to get the glass in. I wasn't planning on being in Reno next week. I was hoping to be in Vegas, with my visit to California over the weekend. But, unexpected change is part of the adventure of travel. The only thing that pisses me off is the cost. It's just enough more than my insurance deductible that it might be worth filing a claim for the difference, but then I don't know if insurance will use it as an excuse to raise my rates, negating the benefit of using it. And if they can't get to it next week, I'm screwed. Either way, it's a gamble but, behold, that is what I'm in Reno for. |
