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.

Requiem for a Year

Well, that was a year.

I know I said yesterday that I'd do a recap or something, but I can't be arsed. Besides, there's not much about this year that I want to remember. Best thing about it is I got my eyes fixed. Yay me.

I'm not one for making New Year's resolutions. I used to, but I do try to learn things in life, like not to keep doing the same thing over and over and expect different results. My mother liked to chant, "If at first you don't succeed, try, try again." Which, now I think of it, is ironic for someone who tried over and over to have a child only to end up adopting one. One who ended up being a gigantic disappointment.

I'm also not a fan of social media in general, but there is one app that I use regularly. It's called Untappd, and it's a place to record what beers you've tried and rate them. I call it "social media for drunks." I kind of wish they also did wine, or at least that I could find a different one for that purpose. But my first love is beer, so whatever.

So I was looking in my Untappd records a few days ago, and discovered something distressing. In 2020, I checked in 648 times. In 2021, my number of check-ins was 520.

I can't go on like this. I mean, a 20% reduction? That's outrageous. So my goal for 2022 is to drink at least 650 beers. They don't have to be all new to me, but I want my numbers back up, dammit.

I know, I know, that sounds like a lot, average almost two beers a day, but remember, a good number of those were from tasting flights. As in, a lot of times, I just took a couple of sips of the brew. The only way, therefore, that I can get back to my 2020 numbers is to visit more breweries and get more tasting flights.

What with everything going on right now, whether that's possible or not is up in the air. But it's something to reach for, and everyone needs a hobby.

Speaking of hobbies...

One-Sentence Movie Review: The King's Man

A movie that reimagines the events leading up to and surrounding WWI and the Russian Revolution, the best thing about this movie was the character of Rasputin; other than that, it's pretty standard political/spy stuff that thinks it's more clever than it actually is, but also features several great fight scenes.

Rating: 3/5

And so ends 2021, and good riddance. Everyone have a happy New Year, and, at the risk of sounding clichéd, see you next year.

As it has become my habit to post one of these just after midnight, remember tomorrow's entry won't follow that pattern, as I will be in no shape to post then. But I'll get one in on New Year's day.

Sometime.
