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 "Je Voyagerai"

I once was allergic to going on a cruise. But... I should... just for the experience. I've gotten out of my comfort zone for experience.

With the crush of tourists these days any travel should include how much you want to put up with "other people's vacation" as opposed to your own.

In response to "It Ain't Wrong"

Ain’t apparently begins as amn’t, a contraction for am not, which you can still hear in Ireland and Scotland today

I mean, an abundant number of Scotch and Irish immigrants ended up in the American South, so this tracks.

While a lot of people consider ain’t improper, it’s a very regular and legitimate part of many forms of English, including in Black English (AAVE). Be mindful that judging someone’s use of ain’t as “wrong” can be a very socially loaded act, to say the least.

For some reason, this reminds of one of the reasons I stopped reading Ask A Manager. A bunch of people were getting real uppity about the use of the phrase "baby daddy". Unsurprisingly, many of these people appeared white. One Black person in the comments finally had enough and threw down with this remark:

"I gotta say, as a black woman it grates to have phrases that come out of AAVE be appropriated, assigned negative connotation (likely because they come from black culture), then discarded with prejudice. If you’re using the phrase to conjure up stereotypical imagery, I can get on board with putting an end to that. But there are plenty of people for whom baby daddy or baby mama are not pejorative at all, just descriptors of the relationship in their dialect, and correcting them to “Father of my child” is just another case of denigrating minority speech patterns and legitimate AAVE grammatical constructions and upholding “white is right” standards."

In response to "Wave Rider"

Horrifying fact, I once painted a reproduction of the Hokusai wave on our bathroom wall. Eventually of course it was painted over, but I like to fantasise that in some distant future it will be archaeologically excavated and held up as an example of early cultural appropriation, (badly executed too.)

In response to "Can't Spell Success without Sucs"

Ok- this made me truly LOL- "sipping a gin and tonic made with low-paid laborer tears"

Thank you. Totally agree with the rest of your article.

Money doesn't solve all problems but it sure as hell eliminates many and makes it easier to go places or buy things that can create some happiness. IE- a property somewhere quiet and peaceful and a trailer with which to chill on said property.

Rich people are typically clueless assholes.

I've never heard anyone say, "That guy is so successful, but he doesn't really make much money." Or anything similar. Sure, you can have a positive impact on the world without making lots of money, but people won't call it success.

In response to "Revisited: "Experience""

Not gonna lie I kinda miss Zoom parties, at least for this community since people on WDC are so spread out. Meeting in person is pretty tricky and/or expensive. It's certainly more socializing than I've been doing regularly since, oh, 2022 or so.

As for server migration, well, I work in the IT world. I've been through that. And honestly, server migration is a bit nerve wracking, as some stuff can go missing. It's still more manageable than a complete redesign. Complete redesigns are awful. You can test in different environments that the public can't see till kingdom come, but things always go wrong when the public version is rolled out. A local grocery store recently redid their website, and the old site held thousands of recipes. When the new site was unveiled, none of those recipes made it over. I ended up reaching out on Messenger and was able to get a copy of a recipe I use somewhat often, but I'm kind of annoyed that the text recipes are currently MIA because somehow that data didn't transfer with the site rebuild. Absolute madness.

Border Dispute

Wars have been fought over less than this.

The Man Who Went to War With Canada
For centuries, the United States and Canada’s only remaining land border dispute has been kept alive by a single family.

Article is from Atlas Obscura and 2019, but the Wikipedia article

suggests that the issue hasn't been resolved over the last five years.

After probably a few hours at sea, they reached the island’s rocky shore, and managed to land among the island’s main residents: puffins, razorbills, murres, and Arctic terns.

If I were that guy, I'd have pointed at one of the latter birds and proclaimed: "It's my tern now!"

Depending on whom you ask, Machias Seal Island is either off the coast of Maine or of Grand Manan. It’s also either American or Canadian. It is the only place with this particular unsettled identity that you can actually stand on top of. Although the ownership of some stretches of water is still contested, this island—and neighboring North Rock, which is even smaller and barer—are the last crumbs of their land the two countries don’t agree on.

Just wait a few years, and climate change will settle the debate for us.

I feel obliged to point out that while I've never been to this island, it sits within easy distance of the easternmost point of the continental US: Quoddy Head Lighthouse. I visited that spit of land when I decided to travel from it to the westernmost point, in the state of Washington. Quoddy Head was the easier of the two to reach, requiring significantly less hiking and way fewer bears.

The article delves into the source of the land dispute, then:

If the world were more just, this would all be moot: The people of the Passamaquoddy Nation likely used the island long before anyone else even knew it existed. (“Machias,” also the name of precipitous local river, is a Passamaquoddy word that means “bad little falls.”) Instead, even as their identifications and affiliations have shifted, the neighbors have kept squabbling over it, like a pair of growing siblings in a shared bedroom.

Look, let's hope it stays on the "siblings" level of quarrel. We don't want to go to war with Canada. We have a history of losing said wars.

The rest of the (rather long) article delves into the American side of things, focusing, as the headline implies (look at that, a headline matching up with the text), on one person's, or more properly one family's, quest to keep the US claim to the island.

I won't quote further, but it's a way more interesting read than the Wiki page.
