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.

Perhaps, if the full moon drives one to madness, the half moon will only make one half-crazy.

In response to "The Numbers Don't Lie"

I hear ya. I like to think I'm discerning enough to detect fakes, but that might just be my ego talking. When it comes to local businesses, I also go to social media and request recommendations. With both reviews from strangers and recommendations from friends, I give more credence when more (anecdotal, heh) details are provided. It's more an art than science, but liars either have such flawless details that their story sounds fabricated, or they get embarrassed when they trip themselves up. Truthtellers make errors, because memories are fallible, but they get more confused than embarrassed. Ultimately, the only way to really know is to try the product/service yourself. Which is why you'll hear about my Cancun vacation next month, but you don't have to believe me.

- I, too, look at the 1-star reviews, though again, reviews aren't my sole criteria. But sometimes it's blatant fake reviewing from the competition: "Don't stay here! It has rats, bedbugs, and roaches! Stay at this other place instead!" where "this other place" is clearly owned by the reviewer.

On the other paw, five-star reviews are often salted by the establishment in question.

Used to be, you could look at the four- and two- star reviews to get more honest, nuanced opinions, but the establishments, and their competition, have figured out that trick.

Which is one reason why reviews aren't my sole criteria.

(None of this applies to WDC reviews, or to the artificially inflated Uber rating system)

And I was going to conclude by saying, when evaluating Caribbean vacation destinations, even if 5,000 people gave it a 4.8 rating, if the one star reviews were from seven people who encountered rats in their rooms, I'm very likely to not choose this destination.

Well, that was annoying. I was still in the process of editing, so please excuse the multitude of errors. I also intended to italicize the quotes from your post. Stupid f****** Parkinson's.

You know what sometimes lies? Anecdotes.

Also, dogs, I've heard.

Oh, hell no.

🤣 I love a good inside joke, but my marketing guru would tell you to cross link here

The fallacy is named after Robert McNamara, the U.S. Secretary of Defense during the Vietnam War, where his over-reliance on measurable data led to several misguided strategies

Bet he's proud of his claim to fame.

What's the point in data, then?

The point in data is a decimal separator, unless here in non-english speaking countries, in which case it's more likely a thousands separator.

So, whenever I'm evaluating online reviews for pretty much anything, and for the record I check them for almost everything - I always consider three things: 1. The average rating (eg, number of stars); 2. The The number of contributors to the rating; and three. What the one star ratings say.

In response to "Waste Not"

In Southern California, every single family residence has a green bin. Every trash day, three different trucks make the rounds.

1 for composting
1 for recycling
1 for garbage

Trader Joe's sells almost exclusively packaged foods, even perishables. They have contracts with college food pantries. In many colleges, there are now pantries that are open to the students 4 or 5 days a week plus 1 day when people from the community can drive up and receive a bag with a mix of fresh fruits and vegetables along with non-perishable foods and donated sundries.

Churches are huge food redistribution centers also.

The "too hard to set up" systems have created good jobs here. Instead of seeing food donations as a liability, they have created a supervised and refrigerated second market.

The cost for employees is small because, of course, many of the positions are volunteers. But the supervisors and some of the staff are full time employees with benefits.

The article has thrown up obstacles that are easy to overcome.

We the people of the world could use those products before they are compost as free sources for 3D printed foods that could be used for emergency food, or if tasty enough, re sold.https://builtin.com/articles/3d-printed-food

Souvenir

PROMPT January 21st

How much of your own life or the lives of people you know do you put into your writing? Do you mine your past for inspiration, or do you create wholly new places and characters?

I mean, I write science fiction and fantasy.

Still, it's inevitable that some souvenir of my past, some moment of doubt or pain, of joy or satisfaction, whether mine or someone else's, will make its appearance in my fiction. And it should go without saying that blog entries are as honest as I can make them, within the boundaries of an imperfect memory as well as a desire to avoid identifying specific other people in less-than-ideal situations. Well... and also allowing for the occasional hyperbole or other truth-stretching for comedic effect. Never let the facts get in the way of a good joke, I say. Or a bad one. Especially a bad one.

It's inevitable, really, that the past should creep in to any writing, as that is all that is real. The future is unknown outside of a few constraining assumptions, and the present is a geometric point on the timeline, without dimension, an illusion, the limit of the recent past and the immediate future. Yes, only the past is real, but, like the grammatical tense, memory of it is imperfect - I was running somewhere, they were singing some song, she was on her way to the prom when...

The minutiae of the past are sometimes sketchy and unreliable, so I use some memory that seems sturdy as a scaffolding, a framework on which to build the specifics. Like the skeleton of a building, this defines the general shape, and while some details are clear on the blueprints, others I have to make up, or pull from other memories. Some other situations - like someone in free-fall in a spaceship - I obviously have no personal experience with, but even there I rely on memory: memory of scientific descriptions, of books, movies, and TV shows that I thought got it right (most don't).

Or if it's a fantasy world, maybe something from a dream will pop in there: terrifying monsters, shifting landscapes, rivers of metal, forests of feathery hair. Again, all part of my past, even if not a part of consensus reality.

Point is, and this goes back to what I've been saying for some time, there's nothing useless when you're a writer. You never know when something you or someone you know has witnessed, or learned, or dreamed or watched or endured, can be useful in writing, perhaps just as a metaphor or simile, much as sometimes, that spice that's been languishing on the rack might be just the thing to transform a meal from merely good to delicious.

Maybe that's why I tend to keep things around: for spice.

A picture postcard
A folded stub
A program of the play
File away your photographs
Of your holiday

And your mementos
Will turn to dust
But that's the price you pay
For every year's a souvenir
That slowly fades away
Every year's a souvenir
That slowly fades away
