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 a seasoned traveler, I have a duty to share some of the knowledge I've gleaned from hard experience. I mean, I could have learned from others' advice and mistakes, but who the hell reads other peoples' travel advice? So, today's tidbit: Never ask the hotel front desk for a dining recommendation. There are several good reasons for this, which in hindsight are obvious, but I had to learn the hard way. First, regional tastes vary widely. Be wary of weird dishes with unnatural ingredients, especially when traveling in the American Midwest. Also, even if the locals eat something approaching normal for you, the receptionist will inevitably be trying to help out their cousin's ex-spouse's kid from a previous marriage, who runs a nearby restaurant, and runs it badly. Every time I violate this rule, thinking, I don't know, maybe the previous dozen instances were anomalies, I regret it. One time, for instance, I got directed to the only Chinese restaurant in town, which had the distinction of being the absolute worst Chinese food I've ever eaten. Which is an accomplishment, I suppose. Another example, from central Missouri (pronounced "Misery"): "You're in luck! There's a truly excellent diner just a few doors down!" So I go to the diner, and it's clean enough, and the workers are really pleasant, but when I got my food it was half undercooked and half overcooked, and how does that even work? Or last night, when I got sent to a sports bar that wasn't supposed to close for another two hours, but they acted put out by taking my order and, as I was eating, destroyed my senses of smell and taste with industrial-strength cleaning fluid while doing their closing chores. Well, at least I knew they took cleaning seriously, which is more than I could say for some restaurants. So instead, just do what normal people do and consult Google. Sure, it can lead you astray, too, but it's more reliable than hotel desk clerks. Or, I suppose, you can just find a nearby chain restaurant, but then, what's the point of traveling? |
