Complex Numbers

by Robert Waltz

Rated: 18+ · Book · Personal · #1196512

Not for the faint of art.

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 "It's a Crime"

Thailand versus Montana versus New York versus Costa Rica.

Theft? Not in Thailand! Not a huge concern in Missoula, perhaps in NYC, definitely an issue in Costa Rica.

Violence? Not a huge concern in Thailand. More so in MT, NY and CR (where it wasn't a concern years ago), definitely a problem in Saint Louis and the US in general. El Salvador is known for violence.

Death by vehicle. Not a huge concern in either NY or MT. A rising problem in Costa Rica. Thailand is one of the worst places in the world in this respect.

You may be shot and killed in parts of the US but you're more likely to be run-over in Thailand.

I get it. The fear spreading jerks wants us to have an "us vs. them" attitude. The division gives them leverage. (they think)

In response to "Butt Of Course"

My wife tried waterskiing once... called it the 100-yard douche.

Talk about retaining water...

In response to "Mad as Hell"

"But if you want to really see how anger is useful, you need to consider how it's used as a tool for manipulation."

This is a line that must be regarded with care. After all, there are people that get angry about the way they are being treated on a large scale and harness that anger to change their circumstances. There is some level of manipulation in this angry but still legitimate flavor of activism. We do have to consider the possibility that this angel's usefulness can have net benefits (such as environmental cleanup and protection; see the Live Canal as an example).

In response to "Supplementary"

Working in health care for a zillion years, I've heard it all. The whole thing about something being natural, therefore it would be good for a person is very, very, very...very prevalent. An internist I worked with had a fantastic comeback to that line of thinking. She would say, "Arsenic is natural, are you going to start taking that?"

In response to "Revisited: "Exercise""

I will be 75 in July. My stepdaughter gave me a bike because I wanted to ride it again. Well, I started off shaky and stayed shaky...then I fell off it...A passing motorist stopped to help me get up...I have NOT been back on that bike and will not ever again.

So, you're saying that now you pedal your ass differently?

In response to "Pleasure and Pain"

it illustrates why it's important to have people from different backgrounds, with different worldviews, working on scientific research.

This right here is why I get rather irritated by people poo-pooing college these days. I feel like that attitude effectively shits on minority populations that may not have strong finances but do possess persistent curiosity and want to learn about various subjects in-depth. In the 90s, these groups were exclusively told to go to trade schools even if they had the aptitude for college education. Nowadays the blanket "Everyone should consider a trade" mantra employs a more subtle (but still abundant) form of discrimination. I'm so over it.

In response to "Going to the Dogs"

I have ants in Thailand. Will I miss them in Montana? No.

Would it be nice to have a cat and a dog, here or there? Yes, but I have struggles keeping my neglected plants alive.

Not every situation is suitable for everything or everybody.

In response to "Tipped Out"

I don't tip. In my travels I rarely find tipping the norm.

I also don't haggle.

When you add the tip... the true cost of America becomes evident. But what would I know? I travel while others who have double my income can't pay rent.

Blog Standard

I've journaled, on and off, for about as long as I could write.

PROMPT July 12th

When did you first start blogging? (anywhere, not necessarily on WDC) Why? What did you blog about? (subjects, topics, personal news, etc.) Has your blogging style changed since you began?

My first blog began in 2005. It wasn't long after I joined here, and I guess I just wanted to start it on New Year's Day. A resolution of sorts, I suppose, back when I still had some interest in resolutions.

It wasn't this one. Back then the blogs had a lower size limit, and I think I was approaching it, so I created this one instead -- mostly because I thought of the perfect title for it. The old one lasted two years; this one's been around for thirteen, though with a very long hiatus. Never could be arsed to turn off the blog entry notifications in my email, either. Six or seven years of "Your blog misses you! Write an entry!"

Before the first blog, I did things the old-fashioned way: scratches on bark, or cuneiform. Okay, no, it was pen/pencil on lined notebook paper.

My handwriting sucks. Always has. I don't know what happened to those old journals. Hopefully they're smoke now. Later, I started using block caps, which are at least more legible, but the writing was just as pathetic.

As with anything, you get better with practice. At least, I hope I do.

I think I gradually picked up the habit of linking things I found interesting and commenting on them. I mean, for a while there I was all about personal stuff, but my life these days just isn't all that interesting unless I'm traveling -- and I have an offsite blog for that, one that makes it easier to include photos.

It's clear that I gravitate toward certain subjects more than others: various branches of science, philosophy, humor, language, music, drinking, and, yes, writing. I try to stay clear of politics because political arguments make me angsty. Sports is barely even on my radar.

Occasionally I'll look back at my old stuff and go "gods, what an idiot." Chances are that 15 years from now, if I'm still alive and can still see, I'll look back at this entry and go, "gods, what a moron." Chances are even better that a whole bunch of people are already saying that.

Still, because my memory is crap (for anything not involving song lyrics), it's good for me to have a record. And if someone else gets entertainment out of it, too, that's great.

So thanks for reading!
