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 "Knead Some Dough?"

I grew up on mostly Wonder Bread despite our family having a large dry farm (dry farm being a farm that grows wheat and barley and safflower without irrigation- it relies solely upon mother nature to rain). I was never fond of it and looked forward to the times my mom would laboriously mill and grind the grain we brought back during harvest into flour and make home-made wheat bread. There was and still is nothing better than fresh whole wheat bread with a little butter and honey.

I think we did the Wonder Bread because my mom wasn't a fan of cooking and making bread is a time-consuming process.

I quit doing the white bread decades ago. There are so many kinds of healthy, no HFCS, etc whole grain breads out there that are delicious that I have no idea why any adult would choose the crappy Wonder Bread.

In response to "The Breakfast and the Breakfurious"

And for those who rather not read the Smithsonian article, the History Channel episode that covers Pop Tarts (if you have a cable TV account):

In response to "Meditation Clause"

Everytime a stranger asks me to close my eyes, I keep my eyes open to see what they are up to.
Meditation is not for me.

But I think most people would have 45 minutes every day if they took that time away from social media or TV watching.

In response to "Super Stew?"

But . . .

What's the difference between one being in the soup or in a stew? Is one thinner or thicker? How do writers use soup and stew?

In response to "Super Stew?"

"Served in a pot? Maybe in your country."

Honestly, in the US I'd think soup would be served in a pot due to the quantity that ends up being consumed.

In response to "Be Positive"

Asking doctors for advice has its own pitfalls. Because there is no money in recommending a sensible nutrition pattern, they will say things like: Look it up online.

In response to "Revisited: "Fail""

Shame on you for making fun of the Hoggs. Being a Virginian, Bob, you should know the reverence that the name Hog inspires recalling the glory days of the Washington Redskins (now the Commanders). The Hogs

In response to "Overdraft Dodgers"

I have four different accounts and each one has a purpose. Savings, personal debit card, auto draft debit card, and a b8lls account. The bills account is the only one that can overdraft as it's for manual big bills like rent, cell, electric, etc. Stuff that mist be paid. The rest are blocked from overdraft and the savings account has no debit card attached. My bank accounts have been hacked too many times so I keep it this way to protect myself. It is very rare I ever pay an overdraft. I have a money market account for money greater than $10K so it gains interest and isn't touched except emergencies. That is a secure account too.

In response to "It's a Crime"

Thailand versus Montana versus New York versus Costa Rica.

Theft? Not in Thailand! Not a huge concern in Missoula, perhaps in NYC, definitely an issue in Costa Rica.

Violence? Not a huge concern in Thailand. More so in MT, NY and CR (where it wasn't a concern years ago), definitely a problem in Saint Louis and the US in general. El Salvador is known for violence.

Death by vehicle. Not a huge concern in either NY or MT. A rising problem in Costa Rica. Thailand is one of the worst places in the world in this respect.

You may be shot and killed in parts of the US but you're more likely to be run-over in Thailand.

Fast Food

Wait... you can make meals?

PROMPT November 11th

What is your favorite meal to make when you are really hungry?

Delivery pizza.

No, I'm not joking.

For the last couple of years, I've been on a meal plan. During the first year, that plus exercise caused me to lose a lot of weight, which is a good thing. Then the pandemic came along, and I started drinking more and canceled my gym membership (yes, it's possible to do that), so the meal plan, at best, now helps me keep off what I've lost. It also has me eating smaller meals more often, which usually keeps me from getting too painfully hungry.

Also, I've been single for a while, so I don't cook much anymore, apart from a few things in the meal plan. It's not that I never learned how; I used to be a passable cook. it's just that I can't be arsed. You know me: maximum return for minimum effort. If it's just for me, I don't bother with anything fancy or complicated; I don't need to show off for myself.

Like anybody, though, I'm not perfect. In fact, I'm less perfect than most. So I don't always stick to the plan -- hence, the occasional pizza. I will say that's a lot more rare now than it was before I began to lose weight. It's almost as if there was a correlation there. I've also all but eliminated other kinds of fast food from my intake.

Things are starting to get colder now, though, and I might have to break down and cook a pot of my chili. But the chili wouldn't count for the prompt; it takes way too long to prepare and cook when I'm actually hungry.

When it comes to "making" food while starving to death, it needs to be something quick and easy, like a sandwich -- but I usually don't have sammich stuff lying around because it goes bad before I can eat it. What I should probably do is cook the chili and freeze serving sizes of it, so when the mood takes me I can just thaw some and plop it into a bowl. But it's not like me to plan ahead like that.

In case you're wondering (you're probably not, though), there's a pizza place near me that is not crappy chain pizza (e.g., Domino's or Papa John's) that usually delivers in 20-30 minutes, unless there's something like a sportsball game going on so that they're busy and there's traffic. So the time between "I'm really damn hungry" and "nom nom nom" is pretty short. The place has been in business as long as I've been in town; it was the first phone number in Charlottesville that I memorized, though these days it's easier to order online. As far as I can tell, their recipe hasn't changed in 40 years.

There's another restaurant near me that has better pizza, but sadly, they don't deliver. They do takeout, however. I haven't been there in a while. Of course, now that I've thought about them, I'm going to have to go. So thanks for ruining my diet.
