Got to chatting with Shrew last night and she had had a long day and was in need of relaxation. So I asked how I could help and she said, “Words.” So I tossed some at her and we let the conversation wander off all over the place.
One of the words I yammered at her was heteroskedastic. I think you’ll agree that it might be one of the craziest words you’ve ever seen. I heard it from Rachael who got it from General Justice, who writes the hell out of some City of Heroes fanfic. (And I don’t say that just cos he took a character I abandoned and made her totally freaking awesome.) Anyway, heteroskedastic has thrown me for a loop. It notably has no dictionary.com definition. There’s an “investopedia” reference to “a measure in statistics that refers to the variance of the errors over the sample.” Okay! Wikipedia breaks it down into “differing variance” from the Greek hetero meaning “different” and skedastios meaning “dispersion.” Making it easier to understand is one of the examples:
Imagine you are watching a rocket take off nearby and measuring the distance it has traveled once each second. In the first couple of seconds your measurements may be accurate to the nearest centimeter, say. However, 5 minutes later as the rocket recedes into space, the accuracy of your measurements may only be good to 100 m, because of the increased distance, atmospheric distortion and a variety of other factors. The data you collect would exhibit heteroscedasticity.
And I don’t know about you, but I have come to two conclusions about this. First, “Heteroskedastic” would make a great name for a band. Second, we’re gonna need some Locrian.
And the others I’m saving for a later day, cos I noticed today I had a nice collection of words that start with H, so let’s keep on it.
I got haberdashery as the subject of some spam this week and it was one of those words I’ve heard and understand, but wanted to learn more about. Plus, it delights the mouth and tongue with speaking. A haberdasher is someone who sells clothes and notions for men. The word is very old and obscure, and is believed to originate with a word for cloth. It seems that there are a few genuine haberdashers left in Great Britain, but they sell what we’d think of as “notions” more than garments. Interesting.
And finally, heuristic. I’ve been going back and forth all week about whether or not this word is new, or I just never bothered with it before. Solid chance either way. Regardless, a heuristic is a test or experiment, frequently using trial and error methodology. It’s some psychology, philosophy, law jazz. And honestly, that’s where my interested ended.
It’s wide, not deep, around here.
