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 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 love my little dog...but I live in a biggish house with a fenced backyard.

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 ...

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?

I have never been to New York, but it seems that my assessment years ago that Berlin, Germany and New York have some similarities. Both cities are known for being inhabited by rude people. And both places, as I now found out, are dog obsessed. And they have high rents.
Berliners though, have a habit of letting their dogs run off leash. Maybe New York is a little better than Berlin in that regard.

Wordsmitty ✍️, far be it from me to speculate on the motivations of space aliens, but why in Xenu's name would they do such a thing to the universe?

I thought humans got bigger brains because extraterrestrials affected our evolution, and we eat processed chicken and eggs.

🌕 HuntersMoon, ah, yes, my favorite words to hear (or read).

Also, that video is an excellent, if brief, explanation of the conundrum and how to resolve it.

Land of Nog

"30-Day Blogging Challenge ON HIATUS" [13+]:
24. Last-Minute Shopper's Day also National Eggnog Day
I should think good strong eggnog would hit the spot after a day of shopping.
See what you can come up with for that one.

Now, look, we all know that I put the "pro" in "procrastination." Hell, the only way I can manage to usually post one of these entries shortly after midnight is to pretend that I'm doing yesterday's entry and submitting it late.

But when it comes to holiday shopping... well, I was done with that weeks ago.

Part of this is because I, by design, have only a few people to shop for. But another part is that even in the Before Time, I didn't go into stores unless I absolutely had to. And by "had to," I mean going into a liquor store because my state has backwards-ass rules about not being able to mail-order liquor.

Everything else, I can and do buy online, issues with Amazon be damned.

Yes, even groceries. I know I've mentioned this before, but I've been having them delivered for at least two years, now.

Of course, there are a few local businesses I feel I should support, and I'll venture into those shops on occasion, but for the most part, everything I need for myself or as gifts for others comes from the internet.

Besides, if I went into stores on December 24th, I'd be subjected to holiday music, and that's a thing I would rather avoid.

Consequently, I don't have eggnog. It's just not something I think about. If I'd gone into the supermarket, I'm sure I'd have seen a display of the mix for it and probably bought it (another reason I don't go shopping: I have poor impulse control and shopping online tends to keep that in check). Then I could have walked across the parking lot and picked up rum at the liquor store -- although at the moment I don't have to because I have plenty of rum.

Now with this prompt I find myself wanting some eggnog... but not enough to make a special trip to the store later today, and finding a delivery slot on Christmas Eve just isn't going to happen. I've got supplies to last me at least through Sunday.

And don't start with the "why don't you make your own eggnog from scratch" shaming. First of all, it's a lot like work; second, and perhaps more importantly, I'd still have to purchase some of the ingredients, at which point I might as well get the pre-made stuff. So no eggnog for me this year. Maybe next year, if I think about it. But probably not.
