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.

As my Grandmother used to say, "Everything changes except that which stays the same." I never did understand why she said it, but it sounds good.

OK. What have you done with the real Robert Waltz?

Also, for the scientist engineer in me, have you actually tried to make entry 3001 and been rejected. Until there's proof, it's not real.

Thank you for your indulgence and sharing of wisdom.

It's been an enlightening run. We wish you well in your next adventure.

It will be interesting to see if after the next entry that WDC actually does stop you from adding another.

We're all waiting on pens and pencils for the unveiling of the new blog and to discover what it will be called.

I'm reminded of this scene from The Princess Bride.

(Vizzini has just cut the rope The Dread Pirate Roberts is climbing up)
Vizzini: HE DIDN'T FALL? INCONCEIVABLE.
Inigo Montoya: You keep using that word. I do not think it means what you think it means.

In response to "Revisited: "In Spite Of""

Tangentially related to 6. Adidas and Puma: During my first tour in Germany, I was assigned to the Army agency that formerly occupied Herzo Base, an airfield probably located within medium mortar range from the sport shoe factories.

As far as German revenge is concerned, I would venture a guess that it's planned down to the smallest detail and executed with appropriate gusto.

In response to "Automatic for the People"

Earlier today I did a bit of shopping. I found a couple of items I had not planned on purchasing on sale so I grabbed them. As the cashier rang them up, I noticed they did not register the sale price, the regular price, but an even higher price. I questioned it and was told this, "The sale ended yesterday, but we didn't get the sign changed. Today the price increased because our cost has now increased." Yes, how did you guess, one of the items was eggs, now over a dollar each!

Another Day

You're not going to believe this -- I can barely believe it myself -- but I think I finally had Enough Beer. At least for now.

This is of course after visiting six more breweries yesterday, and there are dozens left unexplored around here.

After all, I need to save some room for more beer on the rest of my journey, which, again, won't happen until Monday because I don't want to be traveling on the Fourth of July.

Unfortunately, there's not much else to relate about yesterday; there were a couple of Uber rides and a good bit of walking. Interesting place, Minneapolis. I wouldn't want to be here during the winter, though.
