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.

In response to "It's Hard Not To Scare"

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.

Jeté

Wrapping up my entries for June's "Journalistic Intentions"

[18+]...

jeté

(This time, I added the accent aigu myself.)

Long ago, I took a cinema class in college. I might have mentioned this before. No, it doesn't make me an expert on movies or anything; it was mostly an easy B and a different movie to watch every week.

One film that stuck in my head was an artsy French science fiction short called La Jetée. While the words "artsy" and "science fiction" may give some readers pause, it can work. It's also more of a slide show than a "movie," but that's part of the art.

The basic thrust (that's a pun, but you might not know it yet) of the film is that a kid witnesses a death on a jetée (which is the French name for the observation platform of an airport, and yes, it's related to the English "jetty").

Later, after the apocalypse, the guy's sent back into time and (spoiler alert) dies on the jetée, realizing at the end that he was the man whose death he'd witnessed in his youth.

Does that sound familiar? It should. A few years later, when 12 Monkeys came out, I remember watching it and thinking, "I really hope Gilliam acknowledges La Jetée for this idea." And, indeed, he did.

Of course, that synopsis fails to capture the metaphorical breadth and depth of the original film. It really is worth watching, and now that I know more French, I might even try to find a version without English subtitles.

As a verb, the french "jeter" means to throw. The dance term, "jeté," has a meaning closer to thrust (also, it's a past tense construction); hence the really very obscure pun above. Because one doesn't really throw a leg (unless it's a prosthetic); one thrusts it. "Jetée" is a related word (feminine gender) for a structure that's thrust out into something else, like the abovementioned observation platform, or how a jetty is kind of thrust into the ocean.

You can see I'm avoiding the more obvious, salacious puns related to gender and thrusting. Why? Not because they're salacious, but because they're too obvious for a professional punster such as myself.

What I really want to know, though, is this: starting maybe about 15 years ago, a neologism entered the English language. I despise most neologisms, but this one is inherently funny. The word is "yeet," and it's a verb meaning something like "to throw without concern." As in "I watched him yeet the ball right through the asshole's window, then walk away." What I'm wondering is if it's inspired by the French jeter— as the "j" sound sometimes does become a "y" in linguistics.

There's also some confusion over whether the past tense is "yeeted" or "yote," and I'm rooting for the latter.
