Na n/a
I’m supposed to be doing an essay on the D-lines in sodium (hence the post title…as the non-scientists amongst you may or may not know, Na is the chemical symbol for sodium). The acrid yellow glow of street lighting can, on the most fundamental level, be attributed to atomic transitions in sodium. I’m not sure if acrid is an adjective appropriate to the sense of sight, but I can’t help but feel that the searing unpleasantness of their utterly lurid shade deserves this…actually, maybe lurid was the word I was looking for.
Anyway, street lamps are yellow, and I’ve got to write an essay about why.
However, as you can probably tell from reading this and extrapolating that at some point, therefore, I must’ve written it, I’m not doing too well.
My cacti have not been watered for about two months; some of them are starting to shrivel and turn yellow, and one has actually gone brown and crispy in places: I managed to get ’round to watering my cacti three times today.
I also watched a bit of BBC News 24, during which it was revealed that the July 7th bombers did a reccy! Assistant Commissioner Peter Clarke, a wonderfully disparaging man, described this as typical of terrorist methods…to check timings, to check security, to check all those things which they would feel in their own mind they need to get right.
First he patronises the public, revealing the shocking fact that it is typical of terrorist methods
to give intended targets a once-over, then he accuses the terrorists, like naughty schoolboys, of check[ing] all those things which they would feel in their own mind they need to get right.
Aww. The ickle terrorists with their teeny-tiny minds.
I’m not sure what else I’ve been up to, but it must be a fair bit since all I’ve managed is two easy questions and a diagram of a hydrogenic energy levels.
Anyway, probably bed time. ‘Night.
