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?

The Right Word

After yesterday's foray into illusionary metaphysics, I think I'll return to the joys of language.

http://mentalfloss.com/article/50698/38-wonderful-foreign-words-we-could-use-eng...

38 Wonderful Words With No English Equivalent

And the header image is a stock photo of bacon. Can't go wrong with that!

Sometimes we must turn to other languages to find le mot juste. Here are a whole bunch of foreign words with no direct English equivalent.

English, as I think I've mentioned before, is an immensely powerful and nuanced language. But it's far from exhaustive when it comes to describing some things.

1. Kummerspeck (German)
Excess weight gained from emotional overeating. Literally, grief bacon.

Hence the reason for the header image, I suppose. Though I think keto followers would disagree with any link between bacon and excess weight. On the other side, vegans' heads have probably exploded by now.

2. Shemomedjamo (Georgian)
You know when you’re really full, but your meal is just so delicious, you can’t stop eating it? The Georgians feel your pain. This word means, “I accidentally ate the whole thing."

This, however, can definitely be linked to excess weight.

5. Backpfeifengesicht (German)
A face badly in need of a fist.

Lots of these around these days. Some of them were inspired by certain Germans of the last century, so... karma?

7. Pelinti (Buli, Ghana)
Your friend bites into a piece of piping hot pizza, then opens his mouth and sort of tilts his head around while making an “aaaarrrahh” noise. The Ghanaians have a word for that.

"Friend." Right.

19. Bakku-shan (Japanese)
Or there's this Japanese slang term, which describes the experience of seeing a woman who appears pretty from behind but not from the front.

I'm the furthest thing from an expert at Japanese, but this sounds like one of those words that they stole from English and made their own, like "waifu." Sometimes, things come full circle.

20. Seigneur-terraces (French)
Coffee shop dwellers who sit at tables a long time but spend little money.

Funny, haven't covered that in Duolingo yet.

29. L’esprit de l’escalier (French)
Literally, stairwell wit—a too-late retort thought of only after departure.

Nor this - but because I am who I am, I've known this one for some time. Why do you think I'm only amusing in writing?

34. Bilita Mpash (Bantu)
An amazing dream. Not just a "good" dream; the opposite of a nightmare.

Had one of these yesterday. Ever have a dream that was so good you were depressed that it ended when you woke up? Come to think of it, I haven't been plagued by sleep paralysis lately. Maybe it's the daily exercise, or maybe it was waiting for me to realize this before it came back.

36. Luftmensch (Yiddish)
There are several Yiddish words to describe social misfits. This one is for an impractical dreamer with no business sense.

37 & 38. Schlemiel and schlimazel (Yiddish)
Someone prone to bad luck. Yiddish distinguishes between the schlemiel and schlimazel, whose fates would probably be grouped under those of the klutz in other languages. The schlemiel is the traditional maladroit, who spills his coffee; the schlimazel is the one on whom it's spilled.

These are far from the only great expressions in Yiddish. "Luftmensch," by the way, can, if I remember correctly, be loosely translated as "airhead," though I think its literal translation is "air person," which makes little sense in English. Some other great Yiddish words have already been stolen by English, such as "chutzpah," "schnoz," and "glitch." In fact, if you want to expand your vocabulary and sound like a yenta, here you go: https://en.wikipedia.org/wiki/List_of_English_words_of_Yiddish_origin
