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.

In response to "Reality Cubed"

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 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 ...

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?

Socra-Tease

Here's one from The New Yorker that, when I first read it, I thought: This has comedic potential.

When Philosophers Become Therapists
The philosophical-counselling movement aims to apply heady, logical insights to daily life.

I mean, think about it.

"Doc, I'm distressed because I can't find meaning in life."

"That's because life has no meaning, so stop looking for it."

"Wow! That's deep! Thank you."

"Sure. That'll be $180."

"Here's $200."

"Thanks!"

"Can I have change?"

"You already did."

Around five years ago, David—a pseudonym—realized that he was fighting with his girlfriend all the time. On their first date, he had told her that he hoped to have sex with a thousand women before he died.

All the TNY pieces I've seen start out with anecdotes and then, maybe, bit by halting bit, go around and around in circles until they get to something more general. Sometimes they never even get there, which I call "The New Yorker School of Not Getting to the Fucking Point." This one contains a whole lot of anecdotes. My point, which you'll note I'm getting to very quickly, is that I'm going to skip a lot of it here. In brief, he worked with a philosophical therapist named Lydia Amir.

I might have missed it, but I don't think the article notes whether he had sex with her or not.

Between meetings, Amir sometimes gave him reading assignments: Schopenhauer, Nietzsche, Hume.

Oh yes, definitely, if I'm having an existential crisis, those are absolutely the philosophers I want to read.

Amir is one of a small but growing number of philosophers who provide some form of individual counselling. In the United States, two professional associations for philosophical counsellors, the National Philosophical Counseling Association (N.P.C.A.) and the American Philosophical Practitioners Association (A.P.P.A.), list dozens of philosophers who can help you with your problems.

Well. Philosophy tends to pay jack shit. Therapy, however, can bring in the bucks.

Philosophy is both a natural and a strange resource for helping people resolve the problems of life. Ancient philosophical traditions such as Stoicism and Buddhism focussed on practical ethics and techniques for alleviating suffering, but much modern philosophy seems to aim to express suffering, rather than reduce it.

I wouldn't call the aim of those philosophies to be "alleviating suffering," but there's always the possibility that I don't really understand Stoicism or Buddhism.

Some think that the practice of philosophical counselling should be more standardized. Others worry that philosopher-counsellors will miss serious mental-health issues. The two major American professional organizations stress that philosophical counselling can’t address certain severe psychiatric disorders, and urge counsellors to refer clients to mental-health providers when their issues do not fit a philosophical scope of practice.

Well, that's somewhat relieving. It's one thing to seek someone else's point of view, or be able to talk things through with a neutral party. It's another to have legitimate mental health issues that need more medical treatment.

So, anecdotes (and jokes) aside, this kind of thing obviously exists (in the same sense that anything can be said to truly exist), and it mildly amuses me. Does it work? All the TNY anecdotes in the world won't convince me one way or the other; I want to see a study.

I'm sure a philosophical therapist would have something to say about my need for evidence-based science. But, you know. Whatever.
