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 "Pleasure and Pain"

it illustrates why it's important to have people from different backgrounds, with different worldviews, working on scientific research.

This right here is why I get rather irritated by people poo-pooing college these days. I feel like that attitude effectively shits on minority populations that may not have strong finances but do possess persistent curiosity and want to learn about various subjects in-depth. In the 90s, these groups were exclusively told to go to trade schools even if they had the aptitude for college education. Nowadays the blanket "Everyone should consider a trade" mantra employs a more subtle (but still abundant) form of discrimination. I'm so over it.

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?

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 ...

We'll See Who's the Total Moron

I really, really hate self-checkout at grocery stores.

The Banana Trick and Other Acts of Self-Checkout Thievery
“Anyone who pays for more than half of their stuff in self checkout is a total moron.”

But you know what I hate more than that? Well, I'm going to tell you anyway:

Thieves.

Beneath the bland veneer of supermarket automation lurks an ugly truth: There’s a lot of shoplifting going on in the self-scanning checkout lane.

Now, I understand that sometimes, theft is acceptable. Hell, sometimes it's even necessary because of systemic issues. But people who steal just because they can? Honestly, if it didn't disincentivize the thieves to leave their victims alive, I'd support the death penalty for it. Not just the death penalty; torture first.

That's how much I hate thieves.

Self-checkout theft has become so widespread that a whole lingo has sprung up to describe its tactics. Ringing up a T-bone ($13.99/lb) with a code for a cheap ($0.49/lb) variety of produce is “the banana trick.” If a can of Illy espresso leaves the conveyor belt without being scanned, that’s called “the pass around.” “The switcheroo” is more labor-intensive: Peel the sticker off something inexpensive and place it over the bar code of something pricey. Just make sure both items are about the same weight, to avoid triggering that pesky “unexpected item” alert in the bagging area.

I want to find everyone who does this and introduce them to Mister Pipe Wrench.

You're not stealing from the grocery store, you know. They're going to find ways to make a profit, regardless. Not much of one, but if they can't make a profit, they go out of business. When they go out of business, you get food deserts. And if they do find a way to make a profit in spite of these despicable assholes, how does it happen? That's right - by a) raising prices for the rest of us, b) keeping wages and benefits down for workers or c) both.

Either way, you're stealing from honest people and deserve to be flayed alive.

No, I'm not kidding.

The Leicester researchers concluded that the ease of theft is likely inspiring people who might not otherwise steal to do so. Rather than walk into a store intending to take something, a shopper might, at the end of a trip, decide that a discount is in order.

Stores could do more to prevent this sort of thing, but that too costs money. Eventually, you reach a point of diminishing returns, where the money you spend on security is more than the losses involved.

In their zeal to cut labor costs, the study said, supermarkets could be seen as having created “a crime-generating environment” that promotes profit “above social responsibility.”

And yes, that's a problem too. The worst thieves aren't even these checkout scammers; they're corporate assholes.

Whether out of social responsibility or frustration with shrinkage, some retailers, including Albertsons, Big Y Supermarket, Pavilions, and Vons, have scaled back or eliminated self-scanning, at least in some stores.

Which brings me to why I hate self-checkout in the first place. Well, there are lots of reasons, not the least of which is that it never actually saves time since some wage slave has to check my ID anyway because I'm inevitably buying beer and/or wine. But another reason is that it takes jobs away from people. It's not immigrants people should be raging at for "taking our jobs;" it's management's insistence upon automation.

“There is NO MORAL ISSUE with stealing from a store that forces you to use self checkout, period. THEY ARE CHARGING YOU TO WORK AT THEIR STORE.”

Bull. Shit.

“Shopping can be quite boring because it’s such a routine, and this is a way to make the routine more interesting. These can be risk-taking, stimulation-seeking people.”

And when they get caught, 20 to 30 years in Federal prison should give them all the thrills they'd ever seek.

No pity for such people. No tolerance whatsoever. Lock 'em up. I don't even care if it ends up costing society more in the long run; it's the principle of the matter.

...the problem being that because of the way society is set up, some people are forced into thievery, rather than just doing it for the thrill of the five-finger discount, and that is a systemic problem that needs to be addressed. But the court system isn't really set up to be able to tell the difference.

And I strenuously object to being called names for being honest. That alone is worth a few yards of duct tape and a pair of pliers.
