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 "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.

My dreams may be different from your dreams but if we share them with others then some form of the dream may live on. Regardless, if we don't eat we die. "Joy gives us wings." "Reality bites."

In response to "Tipped Out"

Agreed. I'll tip and well, for actual waitstaff at restaurants. I'll tip appropriately for bell-staff who assists with luggage at hotels, the more luggage, the bigger the tip. I'll give a tip to the valet as well. Beyond that- I don't tip. Certainly no tip for the fast food workers, coffee baristas, grocery store clerks, etc.

It annoys me to no end that we're being asked to tip for all kinds of jobs where they are being paid an hourly wage. I've worked as a waitress when I was young and my daughter currently does. In those jobs- she absolutely depends upon proper tipping to make a decent wage. And I hate the fact that she is dependent upon tips to do so.

It leaves women especially at the mercy of arsh**() on whether she wants to accept hostile, negative, sexist, harassing, demeaning, and negative behavior from her customers in order to make a living. It condones people treating their waitstaff like shite in order to get paid. While there is much improvement from the 30 years ago when I was working as a waitress in the skimpy outfits we were forced to wear- it's still an issue at non-chain, independent owned restaurants and diners.

Women are left to the mercies of jerk customers and their only recourse is the manager who they have to hope supports their waitstaff rather than the jerk customer. Tipping should be eliminated. All employees should be paid a livable wage and waitstaff especially should not be dependent upon tolerating crappy to obscene behavior from customers in order to make a living.

But, until that happens- I always tip at least 20% and often times more. Very rarely have I tipped lower and the service in those situations was abysmal and they still got 10%.

In response to "Going to the Dogs"

I don't understand the intersection, either. I lived in a much smaller city and found that having dogs was a hassle (although it didn't stop me), what with the complainey neighbors, the extra licensing, etc. I live in a rural location now and it works great. I can't wrap my head around living in NYC with or without a dog, although I like the idea of a place that issues a canine and supplies upon moving there. Can that please be a thing?

I knew and ate Kohlrabi before I ever heard of kale. Kohlrabi is so much better in every way.

That last quoted sentence is hilarious. I am glad that I wasn't bred to be a Brussels Sprout.

In response to "Cash Stash"

The discussion of money is an interesting one. Remember the recent collapse of a few banks? I think it was about a year or so ago?
Yes, deposits were FDIC insured up to $250,000 per depositor. But some people and companies had more money in that bank than the FDIC was insuring.
I never followed up on what happened to those people. I don't run in circles of people who own that much cash.

My accounting professor took half a period to explain to us what happened and how the bank went from Silicone Valley darling to dead so fast.

He also told us that the value we give money is not backed by anything except our hope and faith that our economy will keep going.

We didn't discuss whether the value of money needed a lower income class of people.

In response to "Revisited: "Hack This""

In my last psychology class, we discussed the evolution of the brain. It is now settled science that we evolved to have not only larger, but also vastly more powerful brains than most other animals because we learned how to cook (process) our food.
Although we are only about 1/4 to 1/3 of a normal gorilla, we eat half of the calories in a day. Not only that, we prepare the food in a way that we get to use more of the calories that we ingest.
The result is that our brain takes up more space in our noggin than a gorilla brain takes up in his noggin. Not only that, each of our brain cells is smaller, so we can fit exponentially more of those into our head.

Now, using all that goodness ...

In response to "Hope for Hops"

Wait! Why are beer and coffee affected by climate change? That wasn't supposed to happen. All we had to do was have a boat by the side of the house for when the sea levels rise and beg our property insurance to cover fire damage. How are we supposed to remember all of that if we don't get coffee to wake us up in the morning so that we can think and beer at night to dull our sense of doom?

Battlefield Earth

Entry #4 of 8 for "Journalistic Intentions"

[18+]

Battlefield Earth

You're all expecting me to rag on Hubbard here, aren't you? Aren't you? But no, the organization he founded has armies of lawyers and this shit is public.

Instead, I'm going to take this opportunity to talk about science fiction.

I talk about it sometimes in my Fantasy newsletter editorials, because there's a lot that fantasy has in common with science fiction. Incidentally, I really hate calling it "sci-fi," but I have been known to abbreviate it as SF. Rarely, though, because that could also mean "speculative fiction," which is probably a broader concept but I can't be arsed to get into the technical nuances of the differences between genres. I'm certain that for some people, it's their hill to die on.

But, as much as SF has in common with fantasy, there are important differences. I mean, yes, I'm intimately familiar with Clarke's Third Law ("Any sufficiently advanced technology is indistinguishable from magic.") I'm also familiar with the people who think they're oh-so-clever and turn it around to "Any sufficiently advanced magic is indistinguishable from technology." That's not nearly as clever as you think it is.

And I'm not saying that there aren't shades between the two genres. Hell, some of my favorite stories are somewhere on the spectrum between the two extremes. And by "extremes" here, I mean that on the one pole, you have magic and maybe the supernatural. The Platonic ideal of this is, of course, Tolkien. On the other pole you have pure science and technology, no supernatural elements, everything is explainable in terms of laws of the universe. I can't be arsed to come up with a Platonic ideal for that.

I do know it's not Battlefield Earth.

And no, it's not Star Trek, either. I love Trek, but it takes too many liberties with the laws of physics to be pure science fiction. Just to be clear, I have no problem with that; it's just a mental categorization thing.

I can also tell you that the difference between fantasy and SF isn't about time period. There's fantasy set in the future, SF set in the past, and all kinds of variations thereof. There's also fantasy set so far in the future that the basis for the magic is actually science, in accordance with Clarke's Third Law.

Before I stopped reading Orson Scott Card's books, I attended a book signing he did. As a published writer of both fantasy and science fiction, he's probably more qualified to discuss the differences than I am, a mere reader and unpublished writer. And he said: "Look at the book covers. Fantasy has trees. Science fiction has rivets."

This was before steampunk, though. Lots of rivets. No grounding in science.

Also, to be perfectly clear, Star Wars is fantasy. Sure, yes, I know, spaceships, warp drive, robots, whatever. All the tropes and trappings of science fiction. But it's not science fiction; it's fantasy that uses SF props. That is a hill that I will die on.

Again, it doesn't matter. I don't feel the need to choose, any more than I need to choose between Wars and Trek, between Marvel and DC. But genre has one important function: marketing. Some people prefer one over the other, but almost everyone wants to know, at least vaguely, what they're getting into when they start a book or movie or whatever. If it bills itself as horror, it probably shouldn't focus on romance. If it's supposed to be a detective novel, maybe don't turn it into a gothic vampire story (or if you do, at least warn us).

Other people might disagree. And that's where the battle comes in.
