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.

In response to "Blond Man's Bluff"

That's interesting about the two spellings of blonde. I always thought blonde referred to the person and blond referred to the hair. But I never bothered to look it up, So you've catered to my lazy today.

Ah... but why did he see those swirls when many of us don't? A totally different discussion... out of thin air... which is a frozen fog today when I gaze out the window.

Humans have great skills of observation; some of us extraordinary skills. Is The Scream depictive or evocative? 😱

Frankly, I'm more surprised to see reasonably good reporting from CNN. I'd given up on their ability to rein in their tendency toward loaded speech.

In response to "Bungalow Bash"

For the love of God, what did I just read? That is by far the worst use case of a bungalow I've ever seen, and a fundamental misunderstanding of the value of front porches—and the size of bungalows.

Was this his point? Nope, I know what his point was. For a guy so worried about presentation, he certainly undercut his own arguement.

"People don't change their minds on the internet. They usually do that in books, battlefields, or not at all.

Yeah, that's a little bleak."

Bleak and also inaccurate.

In response to "Past and Future Intents"

I must live in the present. In the past I daydreamed a lot... probably to escape the bruises of reality; however, I need to be more aware crossing streets or even how I get out of bed (no rapid movements without thinking of consequences).

I can envision a future more peaceful than the present because this time-and-place isn't the only "present" that's ever existed, and I do try to see the larger view (emphasis on 'try').

If the aforementioned exercises don't help; there's still liquor.

Shaking head. Aside from the inevitable Simpson's spider goat song playing in my head which I will now share with you below, whenever I come across a story that has all these scientists doing ridiculous experiments for no logical reason, I must go- ah- scientists- CANCER? You do remember that problem right? Can we maybe cure that before we make cockroaches magnetic and elephants see pink elephants?

spider pig clip- and if you all now are singing the spider goat song- you're welcome! grin

One of your more humorous entries- I especially enjoyed- "Lofoten Vortex can be the name of my Bjork cover band."

Thanks for the laughs. Much appreciated.

Hay Now

This would depend upon their political affiliation.

PROMPT November 10^th

Your neighbor’s hay crop is ready to harvest. Everyone in their family is sick and their Combine is broken. How do you respond to this situation?

Okay, no, not really. I'd help out regardless.

I'm actually not unfamiliar with combines or the process of harvesting field crops... though my experience is likely outdated now.

First of all, if my neighbor's a farmer, then I'm a farmer. In reality, this is too much work, which is the reason I'm not a farmer. But in this hypothetical situation, then I have farm equipment and I'd just use that.

Often, small farmers don't own their harvesters -- they'd have a tractor, because that's useful year-round, but a combine is something most farmers use once a year for a couple of days, and it makes more sense to rent one or participate in a cooperative. You know, like communism.

Or, maybe I could fix the combine. Like I said, I'm not without experience in that area, though a) the latest models have to be fixed by the company that sold them, which is bullshit and b) that's too much like work, too.

The real issue here, though, is: it's a hay crop, not wheat or barley or corn. The main purpose of a combine is to separate grain from straw (basically). No grain, no need for a combine. Hay-making is usually done by a reaper (basically a giant lawnmower), rake (also a giant one that you pull behind a tractor), and baler. First the mower does its work, then the hay needs to cure for a couple of days; the rake organizes the hay into windrows, and then the baler picks it up and poops out bales.

All of that sounds like a lot of work, but you're basically just sitting on your ass driving a tractor, so unless something breaks, it's just time-consuming.

Picking up the bales, though... well. That's a major reason I got off the farm as soon as humanly possible.

You might say it was...

*puts on sunglasses*

...the last straw.
