Complex Numbers

by Waltz Invictus

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 "To Err Is Human"

Right from the beginning I find myself asking, "How many times can anything go extinct?" On a side note, the other day while shopping I saw a neanderthal in the produce section. He was trying to fit in with modern clothes, but it was pretty obvious he was a neanderthal.

In response to "Five Seconds"

Way, way back when I was little, it was a three second rule that I remember. Sometime since it was upped to five seconds because of all the chemical preservatives that are pumped into everything now.

I also ate carrots right out of the garden growing up, I also picked and ate fruits and berries growing in the wild without washing. I do remember food dropped on the floor was either rinsed off and then eaten, or if it was something not easily rinsed, like buttered toast buttered side down, we gave it to the dog.

In our house, there's not a five second rule; unless it's something dogs can't eat, it's whichever one gets it first.

In response to "Need for Speed"

Even with the actual explanation- it still left me going- sooooo what's the difference between the special expensive "speed tape" they use for "temporary fixes" and duct tape? LOL- sure sounds like duct tape to me and they are using it for exactly the same reasons you would use duct tape. I'm guessing that the only difference between it and duct tape is the "speed tape" is slightly stronger and handles temperature differences better. It still comes down holding the plane together with tape which doesn't exactly fill me with confidence. Especially if it's a Boeing plane.

I suppose they call it speed tape to keep people calm. If they called it what it is, temporary repair tape, they may lose passengers.

, I've heard that speed tape is extremely expensive. I can only assume the maintenance guys at Delta got a five-finger discount. But if you're going to steal from work, might as well go big and not just lift a box of paper clips.

In response to "Need for Speed"

One of the last jobs I had was with Delta. I did ask the maintanace guys about that tape once and they pointed out high speed will rip duct tape or any other tape right off. They used it personally for their boats sometimes because of its strength. But looking out a window at 400 miles an hour and 30 thousand feet up and see duct tape on the wing. Certainly made me nervous first time I saw it.

Bad to the Beaune

The association of Dijon with mustard is universally-known and inescapable, but I'm not here for the condiment; I'm here for the wine, because Dijon is also part of Burgundy. As I mentioned a few entries back, Burgundy (or Bourgogne) has a connection with wine that's also universally-known and inescapable.

Oddly enough, despite it lending its name to a particular shade of red (as detailed in an entry I did a while back, "Burgundy"

), the majority of the wines here are white; mostly Chardonnay. It makes a much better wine here than in the US.

In that entry, from way back in February, I said, "Incidentally, these blog entries are inadvertently helping me plan a trip to France." Et voilà, here I am.

But back to Beaune, which isn't actually pronounced like bone: it's south of Dijon and the road takes you through a multitude of vineyards and wine-producing villages. There, while others in my tour group grabbed snacks and ran through some historic sites, I dined at a very French restaurant. Well, I say "very French," but they have an English-language menu, so they do cater to tourists.

We only had two hours in Beaune, and, ideally, I'd have liked to seen the old stuff as well as enjoyed the food, but I couldn't do both. Faced with a choice, it will always be, in order: beer, wine, distilled spirits, food, history. And this place, naturally, offered wine with the food, which included the famous dish bœuf bourguignon. That dish is, of course, another famous cultural export of Burgundy.

The truly amazing thing, though, is this: the meal started with an apéritif, then an entrée with a glass of white Burgundy (recall that in French, entrée is like appetizer), then the bœuf bourguignon with a glass of red Burgundy, and, finally, a cheese plate. I was shocked that it only cost about 80 euros.

So, yeah, I wish I'd seen more of old Beaune, but I have my priorities. I hope to make up for it today by seeing some historical crap here in Dijon. And maybe pick up some mustard.
