Love makes the world go around. Not really, it's much more complicated than that.

Equal Temperaments. Doesn't that sound nice, compatible, and easy on the nerves? It sounds somewhat like evil temperaments.

Equal temperaments is a musical term used to describe a system of tuning and a frequency ratio. It is comparable to a mirror site, although, as in the case of reflections, the mirror image is not identical to the image that we call real, but grading on the curve, it's close enough. It depends, of course, from which side of the looking glass you are viewing the situation.

Are clones identical? Most probably not. They are genetically identical, which is not the same as identical in appearance. Multiple clones would probably look like very closely related family members.

That brings to mind doppelgangers and evil twins.

A doppelganger or double-goer looks exactly like the real person and is thought to be very evil, a portent of death and danger, and usually haunts the real person. Theoretically, if you see your doppelganger, it means you will die soon. At least that is what the doppelganger seems to want you to think. Since the doppelganger is rottenly evil, he loves scaring you and smells your fear, as it were or maybe really so. This gives him or her a psychological advantage, just as if you were competing for a job with someone who was seven feet tall, since height is considered a psychological advantage. Occasionally, a doppelganger thinks he looks like you, while you think the resemblance is not even close. That is when the death portent comes into extreme conflict.

An evil twin is the bad guy, while you are the good guy. It's a black hat versus white hat issue in cowboy terms or an antagonist versus a protagonist issue in literary terms.

That brings up a good premise for a discussion panel, talk show interviews, podcasts and whatnot. It would make for a lively discussion, with both twins competing for the title of Good Twin. People often think of themselves as the good guy, but what is your evil twin thinking?

An evil twin can be quite frightening in the case of spoofing sites and wireless networks.

In cases of twins in utero, one twin often dies before or shortly after birth. I'm sure the living twin would often characterize himself, if given a choice, as The Good Twin,
although not always if you think Goth, vampires, the undead, etc.

The old expression is that opposites attract. This is true. It is also true that similarities attract.

In the study of biology, there are some nice illustrations suggesting receptor sites. In a way, they are like mirror sites, attracted to each other because they are exact opposites. They fit together something like Legos or a jigsaw puzzle. A chemical or molecule must supply the correct fit to attain binding status, otherwise it looks like a Lego construction by a two-year-old. The site must receive compliments in just the right places. Some synaptic receptor sites are ion channels, such as acetylcholine.

Attraction doesn't always mean romance. It is possible to attract flies and mosquitoes, invariably considered pests. The attraction concerns certain chemicals contained in rotten flesh and sugar, or for mosquitoes, blood. Fruit flies are attracted to rotten fruit. Houseflies are attracted to anything that's rotten. You may have heard the expression There are no flies on him. Again, in a way, rotten fruit is like a receptor site. The flies fit right into the purpose of disposing of the fruit. I say this only to illustrate that life and romance often seem contradictory to what you might consider the best probable outcome.
