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?

Oh, Canada...

Today, we go back to Cracked for an article from December about America's Hat.

15 Canadian Words Every American Should Know

And I don't think they're talking about "hockey" or all the extra "u"s in their words.

Either because you're planning a trip to the Great White North, or you just want to be prepared in case you ever run into Keanu Reeves and don't want to look like an idiot, it's not a bad idea to know some Canadian words.

You know, it wasn't even on my radar that Keanu Reeves was Canadian. And I'm usually aware of these things, whether I want to be or not. Well. It's not like he ever chugged maple syrup in any of his movies that I've seen.

As usual, it's a countdown list, and as there are 15 of them, I'm going to choose just a few highlights.

13. “Toque” Basically Means “Beanie”

Yeah, I knew this, thanks to Rick Moranis and Dave Thomas (Canadians). But I rarely have occasion to use the word, because I live in a relatively warm country.

In the U.S., there are Beanies; in Canada, you have "Toques" -- pronounced like the family of Hobbits.

Is it, though? I've always heard it pronounced with a long oo, like in mook or boob, and I thought you pronounced the Hobbit name "Took" like "took." Looking at the word, though, you can't tell: it could be tuck or took or tooook or tock. And you can't even go to the original French for answers, because they call a beanie "un bonnet." Pronounced bonAY of course.

So, like, Jaeyne of the Free Fab Five or any other Canadians reading this... which is it? Or maybe it's regional.

10. A “Snowbird” is Less Fun Than it Sounds

"Snowbird" is a song popularized by Canadian music legend Anne Murray -- but more commonly it's used, not to identify wintery fowl, but to describe the senior citizens who head to Southern U.S. states such as Florida during the colder months...

Hey, we call 'em that, too. When we're being polite.

6. A "Double-Double" is Coffee With Two Creams and Two Sugars

In the U.S., you might know it as a basketball term or a precarious sexual position (we're guessing), but it means a coffee with two creams and two sugars for Canadians.

Hey, Canadians, remember this next time you're thinking of ragging on the drink preferences of your neighbors to the south.

4. “Parkade” is Just a Parking Garage

The word "parkade" refers to a "multi-level parking garage" and appears to date back to Edmonton, Alberta in the 1950s. It's a pleasant word we should frankly all adopt.

I gotta agree with Cracked here.

3. “Pop” Means “Soda”

If you hear a Canadian ask for a "pop," they're not necessarily asking someone to hand over their elderly father. Most likely, they want a soda.

Many electrons have been wasted on discussing the regional variations in what people call carbonated soft drinks. People have actually gotten grants to study that shit. "Pop," as you probably already know, isn't unique to Canada; a huge chunk of the US

calls it "pop" also.

Incidentally, here's a map

of the US, county by county, with visualized results of this important linguistic analysis.

For the record, I call it "soda."

1. A "Two-Four" Means You're About to Get Drunk on Mediocre Beer

A case of twenty-four bottles of beer is often referred to as a "two-four" – and just think of all the extra time you'll have to get drunk thanks to the valuable seconds you saved by omitting that extra syllable.

I suppose we should be grateful they don't call it a deux-quatre. Though this is something I'll never need to know, because I don't drink beer that's sold in cases.

So, like I said, there are a few more at the link, if you care to become bilingual and learn some Canadian
