Diurnal?

awnlee jawking ๐Ÿšซ

In a story I'm working on at the moment, the protagonist asks his AI whether the spaceship he's just captured is operating a diurnal cycle.

What I meant was that there's a regular day-night-day-night progression, but I'm not convinced I've used the correct word. Even if I have, is it likely to be understood by most readers?

Thanks for your help,

@awnlee jawking

is it likely to be understood by most readers?

I saw the subject. I clicked on it to open a new page to open in my browser - but decided the word was so obscure I would go to my dictionary to look up its meaning while waiting.

The word does mean what you think it means, but I suspect very few readers will know it.

I suggest any of the following:
the standard cycle
a twenty-four hour cycle
on Earth time

Ross at Play ๐Ÿšซ

For others who have no idea what it means, according to OED:
1. (animals) active during the day (i.e. the opposite of nocturnal)
2. (astronomy) taking one day (e.g. the diurnal rotation of the earth)

Ross at Play ๐Ÿšซ

It's a damn hard word to parse correctly.
The first mistake I made when I saw it was to assume di- was a prefix meaning two, instead of day.
The second mistake was to mis-see the rest of the word as 'urinal'.
My first guess was something with two penises.

It looks like you are using the correct term, but I had to look it up. Why not just have him ask if there is a regular day-night cycle?

Diurnal cycle - Wikipedia
https://en.wikipedia.org/wiki/Diurnal_cycle
A diurnal cycle is any pattern that recurs every 24 hours as a result of one full rotation of the Earth with respect to the Sun.

I agree with the comments about "diurnal" being a word most people don't understand.

As for the AI involvement, OK, an AI SHOULD understand it but the speaker is going to continue to use similarly "unusual" words to the AI for the rest of the story which will destroy the pace. OTOH an AI should have been programmed to use the simplest language available and relevant so it should not use "diurnal" because some/many/most users wouldn't understand.

If it is the AI asking, the most likely response will be 'Huh? What does that mean?' at which point the AI would have to explain that it means a day/night cycle.

A sufficiently advanced AI should be able to gauge the lingual capabilities of the person it is speaking to and tailor its speech accordingly. So it'll use "5 dollar words" for one person, and simpler phrasing for another depending on a number of factors(potentially including expressed preferences. IE if we used StarGate SG1 as an example, Colonel O'neill would likely get the lay-person version, while Major Carter would be getting techno-babble).

Sometimes the "5 dollar word" is the best option, particularly if you know the person being spoken to can understand it. (Obviously, this is a problem in fiction when it is the READER you're concerned about being able to comprehend what is being said)

The rationale is simple: The 5 dollar word conveys a load of information in a handful of words rather than dedicating a a paragraph or more to talking your way around just using the word. Not quite as pronounced in the case of using "diurnal cycle" instead of "day/night cycle" or alternative phrasing, although "diurnal cycle" still remains the most efficient option, even if it isn't the most effective(as many readers may have never encountered it before).

I was aware of the term previously, but I was expecting Urinal jokes in this thread all the same, not disappointed.

That is too confusing although I got the meaning. Why not just have the protagonist (main character I presume) ask what cycle the AI is operating the ship under instead. From the statement it was a question for the AI to answer.

Vincent Berg ๐Ÿšซ

You could use "circadian cycle", but not only might readers not understand it, I doubt an alien AI would either.

I'd go with:

"Does the ship operate on a Circadian Cycle?"
"A what?" the ship asked, in an odd accent he'd never heard before.
"An Earth based cycle of mixed day and night lighting. If not, my body will encounter problems since our sleep cycles are governed by it."

awnlee jawking ๐Ÿšซ

@Vincent Berg

Thanks for the suggestion.

The protagonist is human. He owns the AI and installs it on the ship over the top of the AI already there in order to make the ship follow his instructions. They are speaking in 'Standard Galactic' (although I might change that) so the story is a translation of Standard Galactic back to English.

FWIW, I polled the writers' group I belong to. More of them had a problem with 'AI' than 'diurnal'.

Crumbly Writer: You could use "circadian cycle", but not only might readers not understand it, I doubt an alien AI would either.

I don't think so. Firstly a circadian cycle is roughly 24 hours whilst such a ship would run on perfect timing. Secondly it seems to exist based on the average 12 hours of daylight and 12 hours of darkness (and we feel differently with15 hours of sunlight). Another planet / universe or whathaveyou may have say a 72 hour rotation and therefore its inhabitants and other life forms would be based on such periodicity. Therefore the use of the word circadian is likely to be misleading to the aliens

Except, there's nothing saying that aliens can't adjust their day/night cycle to cater to whomever their passengers are (think of it like air conditioning in most cars, it's a major selling point for little cost in terms of the price of a space ship). The key would be whether the human would know enough about their own circadian rhythm to describe it to anyone else.

Still, I'd guess the aliens would have mastered the mathematics needed to calculate relative day night cycles for circling planets in a stable system.

Which isn't getting into the weirdness that is circadian rhythms in the first place. IIRC, it's highly variable from person to person should you ever get them in an environment where they can figure that out. (Such as a space ship) But it has been a long time since I looked into any of the associated research.

As memory serves many of the people who have been party to such research usually settled into a "day" that was longer than 24 hours, with 30+ hour "days" not being unusual for participants. So for a space faring society where a substantial portion of the population lives/works in artificial environments, things can get interesting. The people in space may shift to a different time keeping methodology entirely, among other things.

Although even that may not be standardized. Agricultural oriented efforts would likely be more focused on tricking their crops into maximum production, rather than the humans.

A mining colony may tie the length of its day to some blend of "optimum production" from the worker, leisure, and actual rest periods. With leisure being minimized obviously. ;)

While a more generic spaceport with a more manufacturing/commercial/administrative purpose may go for a 30+ hour day just because they can.

Ironically, that may be a beneficial thing for say, a SpacePort in Earth orbit if it is not servicing a specific nation/continent/time zone as that means their "day" would span the workday on much of Earth as well, and ensures they're not particularly bound to any one time zone.

I was aware that it varies (I thought it was more like 22 or 23 hours but so what). What concerns me more is the idea of officially having longer days - 30 or 36 earth hours for example. The average human cannot even concentrate for 60 minutes in a row and is likely to get exhausted after about 8 hours even with a 60 minute meal break. They would need the current 16 hours to recover for the next day's labours.
I used to do very detailed work for a 14 hour day, four/five days a week, 9 hours on alternate Saturdays and 9 hours a day three Sundays out of four. However, alternate Fridays I had to work 33 hours straight through to Saturday evenings. Every day there was two hours travel to add. I survived but we had a high mental collapse rate - that is what work in the City of London can be like.

30 hour days are just not "on" for earth humans.

Probably more on the order of working "4 tens"(already becoming fairly common with some employers) where you go with a 30-hour day so three 10 hour shifts would cover the full day/night cycle. Then after 4 "days" they've hit their 40 hours and get a day off(not two or three as happens currently, as one of those "days" was lost to the longer days to begin with), before going back again.

Obviously, jobs where human psychology works against such a long shift would call for alternative arrangements to be made. Depending on a few factors(proximity to work place) that may translate into going to work twice in a day instead of once. Maybe it's 5 on 5 off 5 on 15 off for example? 5on-10off would also work well on a 30 hour cycle if we're talking a spaceship or spaceport where the worker is literally 5 minutes or less away from their workplace.

I was in the Navy, spent 4 years at sea, I've seen all kinds of shift/duty rotations get put into play. By my own division, and by others on board as well. (That and the non-smokers in particular for some specialties were able to sometimes go days/weeks and occasionally months without seeing daylight...)

6on-6off seemed to be positively brutal, it didn't matter if you spent your time freezing in CIC or in the depths of "the pit" where it could be 110 degrees at the Air Conditioner vent...

Thankfully my division/workcenter never tried that.

Don't forget, when the ships are back in their home ports, the sailors get MONTHS to recover, even though still technically on duty. That helps make up for the high-stress 'maximum productivity' schedules.

In the case of space flight, where everyone on board would have to continue for the next 10 to 40 years, you couldn't get away with such an aggressive schedule, otherwise beings would die!

Ah, but do they fully recover. A friend from Bodo (north of the Arctic Circle) in Norway tells me that they have a worse suicide problem than in the south due to the regular annual periods of darkness. I have heard that Finland has the same.
I wonder if the lack of Vitamin D and its source, sunlight makes the situation worse.
It would thus seem unwise to have long periods of wakefulness away from sunlight or its equivalent. As to the question of adaptation, yes, humans could adapt over generations but I wonder if an earthborn person could fully adapt to a say 24+24 hour "day"

If the day/night cycle for the new world is known, couldn't the AI slowly adjust the on-board cycle during the journey to match that of the destination? That would help the passengers bodies adjust to the new cycle. Of course, that is a moot point if the passengers are in stasis or some form of extended hibernation.

Actually, given the likely duration of each, I'd expect they'd start with one and slowly adjust to the other to prepare the travelers for their final destination (if they knew it beforehand).

Also, while the 'main decks' would probably be lit all day/night, I'd expect the 'residence decks' would be segregated by species, who'd all enjoy similar circadian rhythms (day/night cycles).

With enough experience, frequent usage and a bit of automation, I can't imagine it would be overly difficult to plot the relative cycle for any number of points on the fly, after all, it's all solar system geometry. While it's complex for us, it would be fairly standard for anyone zipping in and out of different planetary systems.

If WE produced a 'ship of the future', that's how WE'd design it, but I'm not sure an advanced civilization would naturally follow that path. Since most animals have varying cycles, they wouldn't function terribly well if served with cookie-cutter cycles, and the crew's productivity with drop precipitously after only a few months in space (forget the 20 or 30 years it would actually take to travel between points in the cosmos).

If I have managed to understand the terminology, strictly speaking that may not be correct. I found this reference via wikipedia (spit!):

https://pubs.niaaa.nih.gov/publications/arh25-2/85-93.htm

"Strictly speaking, a diurnal rhythm should not be called circadian until it has been shown to persist under constant environmental conditions and thereby can be distinguished from those rhythms that are simply a response to 24-hour environmental changes."

Circadian would appear to mean something operating on a 24 hour cycle whatever the conditions, whereas diurnal is for 24 hour cycles corresponding to environmental changes.

As clear as mud, but since the story is referring to a day/night environmental cycle, diurnal seems more appropriate.

Which isn't getting into the "daylight" lights and other such artificial lighting options. In that respect just run "Daylight" lighting in designated work spaces, and use more "spectrum efficient"(lower power use) lighting in the rest of the ship or station. Then you suddenly have people's internal clock naturally trying to "sync" to their workspaces.

The only challenge there is the "customer service" jobs that may be dealing primarily with off-duty personnel. But hey, we have automation options for many of those. The only real challenge would be medical services, and even then....

SAD (Seasonal Affective Disorder) is thought to be part chemical based, but they also suspect some of it is neurological in nature, ie something to do with the brain and the human eye and its response to what it identifies as "sunlight."

http://www.mayoclinic.org/diseases-conditions/seasonal-affective-disorder/basics/causes/con-20021047

Mayo Clinic doesn't mention Vitamin D at all on their list of potential causes. But on that topic, it should be noted that is possible for people to overdose on Vitamin D supplements without much trouble. While going for the "natural method" (sun bathing) will result in your body naturally dropping off Vitamin D production once the "proper levels" are reached. Which isn't to mention a whole slew of other chemicals the body produces in response to sunlight that they're only recently starting to learn about.

Some of which they suspect to have cancer fighting/preventing properties, ironically enough.

Other fun things are conditions like psoriasis where the medical profession can get to be rather schizophrenic about what their patients are supposed to do. As they've found that UV light exposure (to the impacted areas) can help treat many/most patients. But because of various factors, many doctors like to push for them to get their UV exposure "in a clinically controlled environment" rather than just go outside and sunbathe periodically for gradually increasing periods of time. They can't bill you for that. ;)

That's cause both cities are: on nearly the same latitude, near the coast, subject to coastal moisture and cold fronts. Since the Pacific Stream brings cold water south, it generally mixes with the warm air and produces excess moisture (a form of wide-scale fog). Here on the East Coast, our temperatures are anywhere from 5 to 10 degrees warmer than neighboring communities and thus we get substantially less snow, ice and sleet.

There is a vast difference in weather between London and Seattle - primarily due to the ocean currents that affect them.

Despite being at a significantly higher latitude, average temperatures are about 6 degrees higher in London than Seattle during the mid-winter months, and about the same during mid-summer months.

Seattle is affected by a current that has come a long way across the Pacific at the same (high) latitude. That current splits when it hits North America, with almost half going back via the Alaskan coast, and just over half taking cold water down to California.

London is affected by the same current that warms Florida. It travels a shorter distance before reaching Europe, and is heading North as it crosses the Atlantic.

That current is still warm when it reaches Europe!

If not for that warm current, most of Europe would be a similar sort of "frozen wasteland" as across much of Russia and Canada, and the Northern Mediterranean would have similar weather the the Great Lakes.

BTW, London's reputation for fogs is no longer valid. They have virtually because of laws controlling industrial pollution.

Industrial smog gets blown across the Channel and settles in the Thames Valley. Then the EU fines the UK for its pollution levels and greedy councils penalise motorists.

London is affected by the same current that warms Florida. It travels a shorter distance before reaching Europe, and is heading North as it crosses the Atlantic.

That current is still warm when it reaches Europe!

If not for that warm current, most of Europe would be a similar sort of "frozen wasteland" as across much of Russia and Canada, and the Northern Mediterranean would have similar weather the the Great Lakes.

That simplifies it. The Gulf Stream hits Ireland and Cornwall and turns north; the southern French coast is little affected. In summer the sea in Devon ( SW England) seems warmer for swimming than Les Landes (SW France) and Gibraltar west side was about the same as Devon.

Also, because of the melting of the Greenland icecap the Gulf Stream is weakening and will eventually disappear which will make the UK cooler under present conditions (global warming could counteract that cooling)
The Gulf Stream is not the only factor - the 1600s were a time of change from fairs on the iced over Thames to great heat. The 1910 to 1940s were a cold period (I remember 1948/9 winter too well!) and we are now coming through a warm spell - all due to periodic hot and cold.

I was going for the simplified version, noting the Gulf Stream has a significant impact on temperatures across the whole of Europe. ;)

the 1600s were a time of change from fairs on the iced over Thames to great heat.

Are you sure that wasn't the 1700s?

There have been extended periods of extreme global-wide cold, roughly corresponding to minimums in sunspot activity.

Sunspot activity virtually disappeared during the Maunder Minimum, which lasted right through the second half of the 1600s. The Dalton Minimum lasted for about the first third of the 1800s, but sunspot activity was merely very much lower then.

To my knowledge, those periods corresponded to things like "The Year with No Summer" - when the Rhine River was iced over the entire year. There's evidence to support the hypothesis that similar minimums caused famines which resulted in the demise of the Inca and Khmer civilisations, and were the economic trigger for the Napoleonic Wars.

I recall looking closely as historical data for sunspots about seven years ago. The end of cycle #24 seemed so familiar to the one ending about the year 1800, I was sure the coming cycle would be very low. I hoped it would be almost non-existent, but it has been merely very much reduced. There is still a chance the following ones could get further down.

I had hoped another sunspot "Minimum" would bring on another lengthy period of extreme (comparative) cold. I had hoped an extreme minimum would at least mitigate the effects of man-made global warning over the next 50+ years. It currently appears more likely this minimum will not be extreme enough for that.

BUT, at best it would only have reduced the damage caused, AND if the politicians would still have to get their act together soon enough to avoid wholesale disasters. That is not happening, so our descendants will surely fry from the double-whammy of increasing temperatures from man-made causes, plus a return to more normal temperatures when sunspot activity returns to its more typical levels.

The good news for most contributors to this forum is we'll all be dead before that happens. ;)

They did somewhat more than that.

Six main interceptor sewers, totaling almost 160 km (100 miles) in length, were constructed, some incorporating stretches of London's "lost" rivers.

The intercepting sewers, constructed between 1859 and 1865, were fed by 450 miles (720 km) of main sewers that, in turn, conveyed the contents of some 13,000 miles (21,000 km) of smaller local sewers. Construction of the interceptor system required 318 million bricks, 2.7 million cubic metres of excavated earth and 670,000 cubic metres of concrete.
All the open sewers were enclosed & the outflow was diverted from the Thames proper to the Thames Estuary, well away from the main centre of population.

Probably had a lot to do with steam powered everything resulting in a high ambient humidity in significant portions of the city. Electrification probably played a significant role in the reduction in both fog and smog alike as it moved those sources further away from London.

Had something not exactly like that happen in my hometown, where we had very frequent occurrences of winter fog, as well as smog problems when we had not one, but two large phosphate plants running outside of town(and they both pumped out a lot of steam). Most of the fog problem existed within a couple miles of those two plants. They did eventually clean up the smog problem for the most part by the late 1990's, but the fog was another matter.

But by 2000 the company operating one of the two plants decided to shut down operations, pack up the entire plant, and ship it overseas. Fog problem has been nearly non-existent since.

Which isn't to mention a whole slew of other chemicals the body produces in response to sunlight that they're only recently starting to learn about.

Some of which they suspect to have cancer fighting/preventing properties, ironically enough.

Almost exactly what I was going to write.

However, looking at a later posting I read the suggestion that in the lower 48 USA States you could get enough natural exposure (there is an argument about Washington state/Seattle) but surely in the mid west you have winters so severe that body exposure would be suicide and in the summer body exposure would result in a dehydrated crisp
Here in the UK facial exposure year round is possible but in France for example I had winter daytime temperatures of minus 17ยฐC and summer at over 50ยฐC - both unsuitable for skin exposure and made work difficult.

I should add that I was one of a multitude to get skin cancer (mine was mild and easily treated but most were not - two friends must avoid sunlight for the rest of their lives!)

People can, and do, get sun burns while skiing. As to winter sunlight exposure in general, I wasn't really commenting on it one way or another, although "Sun rooms" are a thing as well. They're basically "glassed in" rooms not much unlike a greenhouse, where thanks to being enclosed, the temperature can be controlled. From there an occupant can sun bathe, or not, at their leisure.

My main focus was on the more temperate months and summer, where it then just becomes a matter of limiting your exposure and being properly prepared. Typically speaking, in the summer months in particular, 15 minutes outside sun bathing per day is likely to be more than enough. And a lot cheaper than visiting the doctor multiple times a week for "clinical services."

That and 50ยฐC(122 degrees for us Yanks) isn't that difficult to survive, particularly if you're next to naked and keep yourself well hydrated(sunscreened up if not deeply tanned already, etc). Now if you're dressed like it's 12.7ยฐC(55) and it's that hot outside, yeah, you're going to suffer. Of course you could go the Arab route and put on a couple layers of light, flowing clothes that do little to restrict air flow, but a lot to screen sunlight...

I should add that I was one of a multitude to get skin cancer (mine was mild and easily treated but most were not - two friends must avoid sunlight for the rest of their lives!)

From what I'm hearing, the universal correlation for skin cancer seems to be Sun Burns, not so much sun tans. Particularly when you look to the two major types of skin cancer. Which is where they're starting to correlate information in some other ways.

The most easily treated form of skin cancer typically happens on parts of the body that have seen a lot of sun exposure(which I imagine was the case for you).

While the more difficult to treat cases tend to happen in places that can get burned during sun bathing for example, but doesn't generally see much sunlight otherwise due to shirts/pants/etc.

Also keep in mind that with skin cancer and Sun Burns: up until the 19th Century(and the 20th in many places) the most extreme case most people would encounter is maybe 1 sun burn per year. Because after that, they developed a tan which protected them from thereon which they maintained for the rest of the season because they mostly worked outdoors.

Now move to the present day, where some people can experience(/self-inflict) a sun burn multiple times in a month, because of all the time they spend indoors. And now wonder at the rates of skin cancer being witnessed.

Your second quoted paragraph is right; basal cell carcinoma on the forehead. I was spending a lot of time either building / roofing or on a tractor in sunlight

The other type I referred to is Melanoma - one friend had six places where they had operated. None of them (with one exception)was that active and one was around only for short periods on holiday.

The last one (who also worked outdoors) also contracted some blood disorder which sounds like a form of leukemia - my European Portuguese** wasn't good enough for medical detail. He also will never work outdoors again

(**European and Brazilian Portuguese are very different - I imagine like European French and Canadian French)

That and 50ยฐC(122 degrees for us Yanks) isn't that difficult to survive, particularly if you're next to naked and keep yourself well hydrated(sunscreened up if not deeply tanned already, etc).

Whilst I would normally agree but it wasn't a question of survival but doing a job. Being near naked is not quite safe when handling heavy machinery or sometimes a chainsaw etc in uncleared undergrowth where there are snakes. You need heavy gloves, heavy boots and strong clothing covering all skin.

I am also all too well aware that you can get a serious tan at down to minus 25ยฐC when you are out all day, every day for three months - in those days SPF hadn't been invented.

Now move to the present day, where some people can experience(/self-inflict) a sun burn multiple times in a month, because of all the time they spend indoors. And now wonder at the rates of skin cancer being witnessed

Won't dispute that. UV light causes sun tans, and sun burns, and as I said there is a strong link to sun burns, it would follow that increased exposure to UV light(due to less ozone) would mean more sun burns, meaning more risk of skin cancer.

You're also correct in regards to "more time to sunbathe" (and [almost] burn) in the quest for "the perfect golden tan" which should also result in more risk for skin cancer, particularly if exposed to increased amounts of UV light.

However, that doesn't mean that going out to sun bathe for 15 minutes at a time, every other day on average is going to significantly increase your odds of skin cancer(in most parts of the world, during most parts of the day; I imagine that there are some places that could almost bake you in that time frame after repeated exposure). For many people, that probably would be barely enough to maintain a slight tan, particularly the further north(or south in relation to the equator) you go.

It's working out where those magic lines are, and sometimes a question of being able to do the (medical) testing to find out. Such as the blood testing to determine when you hit your "optimum level of Vitamin D in your blood stream, after which more sunlight exposure is largely superfluous and not needed/warranted/advised.

Yes; those magic lines are the problem and one which is constantly changing.

I haven't bothered about sun tanning since the early sixties when the only thing we could get was a mix of olive oil and vinegar!!!!!!!

Brought up by the seaside and in boats since I was ten I have got semi- immune to tanning. Working on the farm (and it took us three weeks to re-roof it in the hottest summer on recent record) I hardly got any tan - but just a slight touch of skin complaint.

As for sunlight and the body, including but not limited to vitamin D, I have no idea how much and with what frequency exposure is required. Can a summer's daily exposure cover a body for an 7 month winter lack? I simply don't know. As for artificial means I simply hope it is not like the specialist red/blue lights I use for my plants.

The current evidence is that it's your exposure to suntans/sunburns when you were a child that affect your risk of skin cancer as an adult, rather than merely the job one has. It's felt the early sun exposure triggers significant modifications to certain genes linked to specific cancers.

Once you contract melanoma (and have it cut off) the skin (removed) loses it's resistance to sun, so all the surgical scar tissue is ripe for repeat melanomas.

Also, the original inhabitants of Europe were the Neanderthals, who had more protection from the sun. We've eventually lost most of those genes. Part of that was skin color, but that was (supposedly) only a small part of it.

Its why a writer has to decide on the time adjustments and be consistent through out a story. Ship times and planet/system times can be widely different causing local adjustments to have to be made as well.

Making a guess but the Navy probably does that for ships and different ports which would be in different time zones. The ship would have to operate on a regular schedule of crew shifts(term is probably wrong). So ship clocks could be widely different from local clocks.

Navy typically uses whatever time zone they happen to be in for the most part. With a little bit of give or take in the event that they're just cruising through a given time zone, in which case they may delay or accelerate a time shift so it happens overnight rather than when they actually enter it.

There aren't many ocean going ships that could routinely cross more than one time zone in a day unless they're cruising through an area where local government have moved the time zone boundaries around.

That's typically where some other kind of "constant variable" typically gets thrown in, even in the professional stuff. Going back to the Naval Example, ships may run on local time, but the deck log records will reference "Zulu Time"(GMT) all the same.

So if it's hit that point where timing is that critical, then inserting a "twinned" time reference isn't unusual. One reference to the "standard" being applied, and another reference to the "local time" in either order, just so long as it's standardized across the work.
