Friday afternoon I had great trouble concentrating on updating the Diverted Attention fact sheet.
Today I had great trouble staying awake while updating the Fatigue fact sheet.

The Alcohol/drugs one didn't do a thing for me though...

Time for bed and hot water bottle.

Introducing workmates to the little comments that show with xkcd when you move the mouse over the cartoon.

And working out the reason that a bunch of numbers I had were different to the graph in the book I was examining because number of crashes (~10 000 fatal or injury crashes in NZ per year) does not equal number of driver involved in crashes (~14 000 drivers involved in said crashes in NZ per year). And these sorts of things do make a difference.

And making sense (after much patient explanation from a workmate) of the population weights we were using.

Not really much else though.

Weekend time now :)

So, 2 days at new work, with the main conclusion that I need to have nice early nights and get a bit more sleep...

I think work is going divide into 3 areas: lets call them crunch, 20 questions and hot air*. Currently reading up on what is available on the public bit of the web as my computer hasn't been signed up to certain critical bits of software. Most of the previous work has been on crunch and 20 questions, so most of the reading is focussed there, especially since the hot air people are still on holiday and it appears to be a recent initiative (2030??!?).

A few things to note based on what I have read**:

Being male does not increase your life expectancy. Don't know the general population proportions to be able to compare specifically, but there is significant over-representation there. Testosterone and phallic compensation objects really don't combine well.

Slow down and relax. The faster you go, the more likely the accident (or whatever) will kill you.

Don't overtake stupidly or wander into the wrong lane. Head on collisions (especially on open rural roads - see the above mentioned contributing factor) will kill you dead dead dead. Not so many injuries, just mainly dead.

Be careful around trucks. If you run into them at high speeds, they wont notice and you will be dead. The truck driver will be slightly shaken or maybe minorly injured and very upset, but you will be very much past that. Play nicely and remember they have far more mass.

About 20% of Edit: 26 crash deaths (of precisely what sample I can't exactly remember, but I know where to look it up)or more per year could be avoided or reduced to injuries by wearing a seatbelt. That is a lot of people who didn't need to die.

I shall stop being morbid and go to sleep now.

*The paperwork, meetings, and muttering at Microsoft products (bloody top posting) are par for the course and will be accepted as givens.

** Including some sweeping generalisations, but only plus or minus about 10 %.

I can feel my thoat getting a little bit more sore and the world is getting that slight unreal feeling I generally associate with a slight fever...
And I am deriving the final N abundance on the last star, which means I will be done soon. However I also need to enter stuff into a final table and tweak the final graphs* so they are using the final abundances, which will take longer than the 20 min til the lunch time bus leaves.

I could phone home and get Z to pick me up when I am done, but when I left he was ensconced in bed with a laptop, food, drink and painkillers in easy reach with a more advanced case of what I am probably coming down with.

We shall see what happens...

* by running the appropriate +/- abundance ranges, which takes time

I really hate this message:
CHECK THETA-PRL STRATIFICATION
Especially when it is completely unobvious as to why there are temperature pressure stratification issues.
Stupid stellar atmosphere models...

Arcadia (yay to Tom Stoppard plays) is currently showing at Theatre 3. Info at:

The first link says there are cheap matinee performances on two Sat afternoons, but neither of the other website list them. Should try and book for the 6th.
Wish I could see the "Hamlet" and "Rosencrantz and Guildenstern are Dead" performances in Chch... Sigh.

And it looks like dinner combined with Anthony and Cleopatra on Fri (tommorrow)...

Last thing I saw at the theatre was a Chch performance of Les Miserables and before that, Travisties at the Court Theatre (more than 5 years ago).

The heating/aircondition at work is wired such that you have about 15-20 rooms on the same system. This means that everyone on that system has to be set to cooling or everyone has to be set to heating* for the system to work. Do you think you can get 15-20 accademics to agree on whether their rooms should be heated or cooled? Yes to cold mornings, but as to the afternoon... forget it... There are occasional cat herding expeditions as one accademic wants to be warm and tries to find the culpret/convince the rest of his arguement. I haven't seen any fights yet. After Easter the real heating system (hot water pipes) will kick in, but until then...

*Or auto but it does the sulky beeeeeep meaning "I am not going to do that", when I try that.

And on a more positive yet distracted note, must try this, though I may have too long a hair...

And I shouldn't sit at my desk and work out how to sew up the skirt I am wearing, while I am wearing it...
Porrige and work time. Bloody extended atmospheres leading to possible CO emission AND absorption... It doesn't look like the model though...:(

That book meme:

1. Grab the nearest book.
2. Open it to page 161.
3. Find the fifth sentence.
4. Post the text of the sentence in your journal along with these instructions.
5. Don't search around and look for the coolest book you can find. Do what's actually next to you.

The spectrum is computed using eg. (7.16),
[eqn for flux as 2 pi times an integral between negative infinity and infinity of a function involving the source function, optical depth as a function of wavelength, opacity as a function of wavelength and other numbers - I could do it in Latex...]
with Snu(tau0)= Bnu[T(tau0)] in the LTE case, and where the optical depth scales are related by
dx=d taunu/kappanu rho = d tau0/kappa0 rho
or
[eqn I ain't even going to attempt to try...]

"The Observation and Analysis of Stellar Photospheres" by David F Gray. Yes, I am at work and oddly enough I am writing this while waiting for programs using these equations and others to generate a model spectrum.

And since they have finished running, I should get back to work. I wont waste time in trying to learn HTML markup for greek letters...

Nothing like calming down from wanting to strangle people by finishing the main seams on a leather satchel. Now all I need to do is decide how to attach the tablet woven handle and do so. Lots of people at the AAF craft night. Plenty done and lots of fabric sales - Z made the price of the 45m wool back and more people still want to buy some... and more than half left.

Not really looking forward to tommorrow though. Shock waves play merry hell with the boundary conditions when right in the innermost layers. Nothing like seeing the 20 year expert comment on never having seen THAT before...

Sleep first though.

Tent 2 is now started (read the roof pieces have been cut out and pinned together). Nothing like overcoming inertia... Sewing machinage will start this evening. Oh, the joys of thread tensioning.
Tent 1 still has to be finished. There are ongoing discussions/deliberations about waterproofing. And we need a large open _flat_ area of ground to set it up on for sorting out the door seams and closure placement.

Yay for being in a house with a large enough lounge area to measure out 7m long roof pieces. At least we are not having to work down the corridor, through the kitchen and into the dinning area.

I don't have any good starting model atmospheres. Sigh. The best prospect in terms of not given a starting error for wrong temperature - pressure scale turned out to try and produce a divergent set of solutions. Since this star does not have a split personality, this is unlikely to be physically realistic. Drawing board please... and additional points of view. Unfortunately can't pester one until he turns up in Aussie this weekend. Time to see if the other is in his office.
