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.

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.)

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.

In response to "Discomfort Zone"

Just so everyone is clear:

- There are credit cards and debit cards and even cash cards. They are treated differently by different places as some prefer debit and cash over credit (which usually chrages the merchant more).

- As Annette mentioned, using text and wi-fi is best and usually cheap or free included most US phone plans. However, 'data' outside N. America is not. If you want to wander streets and go hiking and check maps or GPS in Europe, make sure you have a data plan for Europe. That's where the thousands of dollar charges come in if you don't have that. Voice also is usually extra. So if you plan on a lot of talking, get a plan for that, too. (As I recall without an additional plan for Europe, standard charges were 25 or 50 cents for each text and and a dollar minute for voice.)

- On phones, you may have to turn on or unlock the ability to use European system as it communicates differently than the one used in the US. T-Mobile does have good info explanaing that and data plans once you find it on their site. I think there was a search to input your phone make & model to show you what will make it work outside N. America.

In response to "Discomfort Zone"

Funny thing is, everyone mentions day to day spending in cash, but I don't recall seeing a single person in the Netherlands use cash in the grocery store. I was in a couple different grocery stores and a convenience store outside normal tourist areas, and cards were preferred. Even in museums there were readers to get donations from cards instead of having boxes out to drop off cash donations. This may be less of a thing in smaller communities, but I do feel like some of the larger (non-tourist) communities are going cash free. The pandemic's legacy of contactless payments sure has been a weird one.

I think that SIM card thing is over now. Check it out though. I didn't change my SIM card and I my bill was the exact same as always. I did only use texting and wi-fi though.

Can't Spell Success without Sucs

Okay. Fine. Sometimes, clickbait works on me. It draws me in, fuels my outrage, makes me want to read more so I can rant about it..

Richard Branson says money isn't a good way to measure success: Focus on this 1 word instead, it's 'all that really matters'

Which is exactly the kind of thing I would say if I were a billionaire and the poors kept grumbling about dragging me and my head to a guillotine. It's like when they try to convince us that "money can't buy happiness" while they're flying in their private jets, smiling and sipping a gin and tonic made with low-paid laborer tears.

But let's hear this rich guy's take on it, anyway.

Richard Branson doesn't want to be defined by his money.

Well, you could give it all away and see how you're defined then. (Preferably, to me.)

"Maybe in America, 'billionaire' is a sign of success, but that rankles me," says Branson. "I think that your reputation is what you create."

Didn't his company declare bankruptcy recently? Oh, yeah, one of them did, last year.

Such success.

The company is largely responsible for his estimated net worth of $2.5 billion, according to Forbes — but he chafes at the idea he created it to make money.

Bet he wouldn't have done it if he didn't think it'd be profitable, though.

In fairness, $2.5 billion is small potatoes compared to people like Bezos or Musk, both of whom I mention because they're his direct competitors in the spaceflight field.

Of course, success is never guaranteed. If you do follow your passions, you'll still need factors like talent and perseverance on your side to avoid falling flat, experts say.

Mostly, though, you need luck.

And the real reason I decided to snark on this article? (In truth, I have nothing against Branson.) It's that the article ends with a promotion for one of its publisher's offerings, and the ad begins with the bolded phrase: Want to make extra money outside of your day job?

Still not sure if that constitutes irony or not, but I got a good laugh out of it.

Regardless, sure, success can only be defined by the individual. But having lots of money, no matter what problems it might bring with it, is always better than wondering how you're going to make rent next month.
