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.

Instant potatoes? Yes, I enjoy them, too. We also use them for thickening up soups and stews.

In response to "Linguistic"

- I appreciate the recommendations, but I canceled Netflix when the choice was to put up with ads for a lower price or pay a shitload of money. If it were free with ads, I'd manage like I did in the days of broadcast TV, but I flat-out refuse to both pay money and watch commercials, which is why I never had cable TV.

The price for the ad-free experience also went up to the point where it wasn't worth it with the amount I watched.

In response to "Linguistic"

I refer to my three languages as three different brains. In France, I activate my French brain. Which made for some funny turns of phrase when I was speaking to my son in English with English words, but in French syntax.

Netflix has some really good multilingual TV series. I recommend

- yeah, I edited out the duplication, because it could be seen as a refutation of itself.

I use translation tools all the time... and subtitles on youtube.

My French pronunciation is okay because I learned it as a child; my Spanish is okay because I practiced it. I slip into both with one key exception. French is easier when I'm depressed and Spanish can draw me out of depression.

Speaking multiple languages has also been linked to delayed onset of dementia symptoms.

Yes, I saw that you repeated that. It bears repeating.

Speaking multiple languages has also been linked to delayed onset of dementia symptoms. Or so I hope.

In response to "Revisited: "Hush""

Well as someone who only hears out if one ear..I prefer to be able to hear completely any sound or noise or whatever. There are sounds you never would miss until you can't hear them anymore.

Anyway each to their own..I also prefer silence at times too.

Keep writing.

In response to "Ignorance is the Opposite of Bliss"

Kåre เลียม Enga

- While competition is often touted as the driving force of progress or evolution, it's actually cooperation that's most important. Even opposing sportsball teams, while seeming to be in competition, have agreed on a set of rules, the enforcers of these rules (referees or umpires or whatever), and the penalties for breaking the rules.

The Space Race is another example. On the surface, it was a dick-measuring contest between US and USSR. Each country relied on internal cooperation, obviously, but they also cooperated with each other—if only through things like weapons treaties and promises not to go to war over it.

Competition is a factor, of course. But survival depends on cooperation.

In response to "Ignorance is the Opposite of Bliss"

Denver Broncos beat the Cleveland Browns... just saying. No, I didn't know. I looked it up! And although I know a thing or two I rely on the experts behind google to find out for me.

Is this blog entry pertinent? As Our Dear Leader fires experts left and right (but mostly left, because he's always right), we're left with loyalists who may or may not be experts or have any knowledge of the field at all.

You delineate the weakness of competitiveness. One ring to rule them all negates the contribution of millions. In the case of reaching the Moon or Mars, the crew cannot be competitive and even the technicians have to be a competent expert in what may be a detail (like proper heat shielding for any shuttle). China, USA and India can compete on getting to Mars; but, it will be a cooperative crew of experts that gets there.

I loved reading my poetry to a group of writers who could pick it apart. I miss that. Since I am the boss, I don't have to change one comma and I can ignore their suggestions... but I'm better off doing that than submitting to an AI program that reduces everything to General American for an audience of 12 year old Vacation Bible School students (a.k.a. the education system of Southern Baptist Confederacy of Oklahoma).

In response to "Steaming Ship"

Thanks for clearing that up. On a side note, if I have a 16 foot fishing boat and stick my kayak in it, is it now a ship?

Speaking of space "ships", I've often wondered why the termed the craft used to shuttle people/beings between the planet and ship, or even between ships, shuttle-crafts.

In sticking with terminology, if the larger vessel is a spaceship and carries smaller crafts, shouldn't it be a spaceboat?
