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 ...

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?

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.

Leadershit

PROMPT September 8th

Prompt today is submitted by Elle - on hiatus

!

What do you think makes a good leader? Share an example of a good leader from your life (or alternatively, a poor leader who taught you what not to do).

It helps to have rolled a high Charisma score.

Aside from that, well, I think a good leader motivates, encourages, kicks butt when necessary, knows when kicking butt is necessary, reads people, understands a person's strengths and weaknesses, and, probably above all, leads by example.

I worked with a guy for 15 years who mentored me in engineering. He'd answer questions, show me efficient ways to do things, and help keep me focused. We had somewhat different skill sets, at least starting out - I was always the computer nerd, while he was more old-fashioned with a pocket calculator - but gradually we picked up each other's skills.

After those 15 years, he left to start his own company and poached me from our old one; we were both dissatisfied with the way the boss was running things. A bunch of people left all at once. So I started working for him directly, and that's when things started going to shit. He'd emulate our former boss by coming in late, taking long lunches, leaving early, and generally fobbing off most of the work on me. Not a great example. This was especially disappointing to me because, while we were never friends outside of work, I thought we had an understanding. When you know someone for 15 years, you think you actually know them, but things change, I guess.

After a couple of years of this, I left with another of his employees to start our own firm. Karma can be a bitch. At that point, I was still doing all the engineering work (my partner was in another discipline), but at least I was reaping the rewards as well.

My business partner and I never had more than three employees, but I like to think we were better to them than my bosses had been to me. I don't know; I don't have much to compare to. At least I tried to lead by example.

These days, I'm happy being responsible for no one but me and my cats. Not that I don't have other responsibilities, but they're hardly onerous.

I don't know what happened to my former co-worker turned boss, by the way. I hope he ended up successful. I don't hold a grudge; I just couldn't be in that situation any more.
