Complex Numbers
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.

Another month gone - always surprised at how fast they go by, now.
One more month left in the year.
As much as the "holiday season" sometimes gets on my last nerve, I do like the week between Christmas and New Year's. That's what I look forward to - the time when everyone else is finally coming down from their holiday highs, and sanity prevails everywhere (except, of course, at retail store return counters). No one has yet made impossible New Year's resolutions, and things are just generally slow for me.
Then there's New Year's Eve. I don't always do traditional stuff on New Year's Eve, but it's something I always enjoy. Not just because of the drinking, but because it's a kind of closure for me. An artificial one, since the year can really begin and end whenever we decide it does, but that time is one we can share with friends.
First I have to get through the next three weeks, though - part of that in New York City.
I'll manage. |

Okay, I can deal with paying hundreds of bucks to be tortured by a dentist. I can deal with lying there with a big rubber thing in my mouth and being unable to swallow or breathe naturally. I can deal with the soreness afterwards. I can even deal with the time it takes, and the anesthetic, and all that.
But next time I get a root canal done, it will NOT be in the Christmas season when I have to listen to the ALL-CHRISTMAS music piped in while I can do nothing but lie there imagining the horrors being visited upon the inside of my tooth.
AND now I have to go back there next week so they can finish the procedure.
I'm buying earplugs. |
