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 "Supplementary"

Working in health care for a zillion years, I've heard it all. The whole thing about something being natural, therefore it would be good for a person is very, very, very...very prevalent. An internist I worked with had a fantastic comeback to that line of thinking. She would say, "Arsenic is natural, are you going to start taking that?"

In response to "Revisited: "Exercise""

I will be 75 in July. My stepdaughter gave me a bike because I wanted to ride it again. Well, I started off shaky and stayed shaky...then I fell off it...A passing motorist stopped to help me get up...I have NOT been back on that bike and will not ever again.

So, you're saying that now you pedal your ass differently?

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.

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?

We Got The Beat

Hey look - it's a link about writing.

‘I don’t care’: text shows modern poetry began much earlier than believed
Academic finds that lines widely reproduced in the eastern Roman empire are ‘stressed’ in a way that laid the foundations for what we recognise as poetry

"I don't care?" Wow, Generation X is older than I thought!

For Taylor Swift, the “haters gonna hate”, but she’ll just “shake it off”. Now research by a Cambridge academic into a little-known ancient Greek text bearing much the same sentiment – “They say / What they like / Let them say it / I don’t care” – is set to cast a new light on the history of poetry and song.

Good thing that copyright long ago expired, huh?

The anonymous text, which concludes with the lines “Go on, love me / It does you good”, was popular across the eastern Roman empire in the second century, and has been found inscribed on 20 gemstones and as a graffito in Cartagena, Spain.

I mean, seriously, how many of us have seen poems like that? Or, well... written them?

In my defense, I was 14.

Before the emergence of stressed poetry, poetry was quantitative – based on syllable length.

Honestly, this is a distinction I never could wrap my head around -- hence why most of my forays into "poetry" are doggerel or parody.

“We’ve known for a long time that there was popular poetry in ancient Greek, but a lot of what survives takes a similar form to traditional high poetics. This poem, on the other hand, points to a distinct and thriving culture, primarily oral, which fortunately for us in this case also found its way on to a number of gemstones,” said Whitmarsh.

This kind of reminds me of children's rhymes. Not the widely-known ones, but the ones that rarely, if at all, get written down, and are passed down to younger children exclusively from older children, who continue to pass it down in an attempt to look cool. Since they're not written down, they usually transform like a generational game of Telephone (what do they call that these days, anyway? "Reply All?")

This poem pushes back the earliest appearance of stressed poetry by at least 300 years,” he said. “It has this sort of magnetic rhythm to it, four beats to the bar, a stress on the first beat, and weaker stress on the third beat, which is rock’n’roll and pop music as well.”

I once heard a theory that rhythm -- whether drumbeats or poetry -- was connected to heartbeat. No idea if that's the actual case or not, but it makes sense.

I also find it fascinating that, even in classical antiquity, there was a distinction between "low art" and "high art," and this seems to be one of the few instances of "low art" that survived. I suppose it's possible that a lot of modern music, especially folk and the like, owe its existence to those half-forgotten words and rhythms. A message across time. We may be facing different challenges now, but we're not so different than those working-class Greeks of old, are we?
