Until recently, when Tweetdeck's search facility decided that underscores are really spaces in disguise, so the above search gets a hit any time somebody talks about a toasted cheese sandwich. Which, oddly enough, is kind of a lot. Certainly lots more than business to do with the Journal.
I'm pretty sure I had another one... But now, here I am in the (html-metaphorical) kitchen and I can't remember why I came in here. Don't you hate it when that happens?
There's an off-by-one "feature" built into spectroscopic nomenclature. I guess, like a lot of these things, it kinda made sense to somebody in 1930, but we never throw anything out, so there you go.
A few colleagues and I were talking recently about measuring x-ray lines that come from the recombination of 8-times-ionized neon ions, naturally enough denoted Ne8+, or by old fashioned folks like me, Ne+8. Same diff.
Back in the '30s, or even before, somebody decided that the First Spectrum of Neon should be that of the neutral atom, the 2nd for Ne+, and so forth. One writes these things with Roman numerals. So we're talking about a reaction like this:
For those who are paying attention, we're interested in the radiative decay of the neon ion on the right side, the 7+ one, which emits x-rays in the spectrum denoted Ne VIII.
I think at least five times in the last couple weeks, each and every one of us has slipped up and gotten confused due to the opaque nomenclature.
MLP time: mountain gorillas come touristing to the camp of some people who are there hoping to see mountain gorillas: Clickety.
Actually, I recommend following thekidshouldseethis.com on rss or whatever; they have videos that are sorta science related several times a week, and often they're very cool things.
Oh well. If it comes to me, I'll have grist for another diary.
