We interrupt your annually-scheduled trip blogging to say that "Remembering Light" has gone live at Beneath Ceaseless Skies. Fans of Driftwood, enjoy!

(The rest of you are also encouraged to enjoy, of course. But there are certain people who have been pestering me for more Driftwood stories, so I wanted to address them in particular.)

I dawdle a little this morning because I have to wait for the Bank of England to open at 9:30, so I can go exchange some old pound notes I brought with me. On the way back from that, I detour on impulse to the Guildhall library, where I waste half an hour waiting for a book that turns out to have gone missing. But the visit itself is not a waste, as the helpful librarian (I've yet to meet a non-helpful librarian at the Guildhall, or indeed at most libraries) tells me the king of thing I'm looking for -- a survey map of London's Victorian sewers -- has been moved to the London Metropolitan Archives. Particularly alert readers will recognize that name from my Ashes-trip adventures in secretary hand. The archives, of course, are in Clerkenwell, and it turns out that on Thursdays they're open until 7:30. I may also be able to get the info I want at Abbey Mills, but it's worth trying this first, because it's closer, and I have a catalogue reference that looks promising. So much for the quiet evening I had planned, eh?

Actually, my whole plan for today is a bit borked. Which turns out to be a bit of a theme. )

My feet are feeling rather abused -- though not in any surgery-related fashion -- so I don't know if I will commit the stupidity I'm thinking of for tomorrow. We'll see in the morning, I guess.

By the way, stay tuned for a second non-trip post in a little bit. My hostel has vastly improved its pricing for wireless, so I'm much more able to handle side tasks this year; this is very fortunate, given the things I keep having to take care of. Anyway, I have a question I need answered semi-urgently, but I'll put it in a separate post.

If you're a math-and-science type person, please read this and give me your thoughts.

Tonight I thought up a question that really shouldn't wait until after my trip is done, because depending on the answer, I may end up working it into the revision I'm trying to do while I'm here.

Before the question, though, the background: Charles Babbage designed two devices, the Difference Engine and the Analytical Engine. The former is essentially a calculator, doing polynomial functions; the latter (had it been built) would have been an early computer, capable of being programmed to do several different mathematical jobs.

So imagine you're reading a book set in 1884, and it tells you that faeries got hold of those ideas and built them, But Better -- for values of "better" that involve extrapolating this design in a magical direction. My question to you all is twofold. First, what extrapolations would you consider reasonable, given the parameters? Second, what extrapolations would make you say "Oh please" and put the book down? Example: "It would be cool if it could do calculations using imaginary numbers, but dumb if it could run World of Warcraft." Or whatever. In essence, I want this to be interesting, but I don't want it to be interesting in a way that's totally divorced from the original purpose of the design.

I'm soliticing feedback because this is, among other things, a matter of the boundary between "suspension of disbelief" and "excruciating torture of disbelief." Which varies from person to person, though math-and-science type people are likely to have a much firmer boundary than those who don't know Babbage from Byron. Also, thanks in part to a declining series of math teachers in my education, I no longer have much love for the subject; ergo, if I ask my brain to think about "math magic," it pulls up images of workbooks designed to make third-graders believe math is fun. So I am ill-suited to judging what I can get away with designing. Would it bother you if the faeries' Analytical Engine performed non-numerical calculations of some kind? What if its function was predictive, analyzing a situation to make semi-divinatory, pseudo-statistical descriptions of the future? Would something like that bother you? What wouldn't bother you, that also isn't so mundane that it wouldn't add much to the story? (The other ideas I've come up with so far all fall into that latter camp.)

Feel free to respond however you like -- brainstorm, talk amongst yourselves, go off onto wild digressions about nineteenth-century math. I know some of you have thought about math + magic, so I'd love to hear what you have to say.
