I find it interesting that in Swedish the opposite of sunwise is "motsols", i.e. counter sunwise or literally "against the sun". Sunwise is called "medsols", lit. "with the sun".
Yep - in the northern hemisphere a sundial shadow will move from west to east in a clockwise fashion; in the southern hemisphere it still goes west to east but does so moving anticlockwise.
I somehow read this comment in the voice of the cleric performing the "mawwiage" ceremony in Princess Bride.
Cleric: "Sunwise...." long, uncomfortable pause. "And for the exact same weason." Pause. "Clocks go clockwise because their pwedecessors did... and what were their pwedecessors?"
Humperdink: "Look, can we hurry this up?"
Cleric: "Sundials."
Humperdink: "Just skip to the end!"
Cleric: "Countewclockwise... as said in another comment... would be... widdershins."
Sundials are also responsible for why we say "o'clock". It's a differentiatior. Because the speed of a sundial would vary based on the time of year while a clock was constant, you had to clarify what kind of time you were talking about. Did you mean 10 of the clock or 10 of the sun? (Basically no one said o'sun, if you didn't specify, it was assumed you meant by the sun.) Somehow, that stuck around long after sundials fell out of common use.
You just made my brain click. I've always wondered why clockwise rotation around a vertical axis was commonly agreed. I have never seen a mechanical- or electrical clock installed flat on the ground. So why would we assume that the clock isn't in the ceiling facing down, which would reverse the direction?
But now that you mention it in the context of a sundial, it seems so obvious that the clock is just an extension of that, making the sun and clock a common reference.
But that bids the question if they have another term for it in the southern hemisphere.
It's been very difficult to find an answer for this, and I suspect it's because most of the southern hemisphere is water, and most of the rest of it was colonised by people from the northern hemisphere. As of right now, I couldnt say if there simply weren't words for that kind of rotational motion or if my google-fu simply isn't strong enough.
The best answer I've been able to find is from Indonesia, which is equatorial. The word "sunwise" translates into a phrase "from left to right" via Google Translate, but that may just be an artifact of machine translation.
I've just find (in wiktionary) the word "moonwise", meaning antisunwise/counterclockwise. But the moon moves the same way as the sun does. So is there some deeper meaning based off of some long-term patterns in lunar movement, or is it just simple antagonism sun×moon?
That's what it appears to be. This is supported somewhat by the term "moonwise" not having a lot of historical usage, leading me to believe that it came along much later by someone who wanted a related antonym.
The only bit about the moon that seems to travel right to left are it's phase changes, and even that is because we're outside the rotation and watching along it's horizontal plane. You'll see the same thing with anything spinning clockwise in front of you: the closer edge goes right to left, the farther edge goes left to right.
Well, clocks are just mechanical sundials. Before clockwise, there was sunwise (or deosil), and clocks' movements are based off of the movement of a shadow across a sundial.
Yes, when you are in the northern hemisphere, a sundial shadow falls to the north of the gnomon (the thing that makes a shadow). This makes the shadow move from the northwest to north to northeast over a day, which is clockwise. In the southern hemisphere, the shadow from the gnomon falls to the south, so it starts in the southwest and moves to the south and then southeast, which is anticlockwise.
The most obvious way to see this is the photo of the sundial in Perth, where the hours run anticlockwise.
It wouldn't be that hard. Once you get a clock like this with the reverse movement, you can just open the face glass, remove the hands, and print a new graphic for the background.
I have one of these, it was a gag gift from a friend. I've had it up so long now though I have to double check which clock in looking at before I tell the time because I've got so used to it
Also why the seemingly arbitrary graduations, 24 hours, 60 minutes, 60 seconds. If it was say 10 hours in a day, 100 minutes in an hour, 100 seconds in a minute, seconds would be close to the same amount of time. Same with latitude and longitude, why 360 degrees in a circle with 60 minutes in a degree and 60 seconds in a minute.
These numbers aren’t arbitrary, they are from different base numbering systems.
60 can easily divide by 2, 3, 4, 5, 6, and 10.
12 can easily divide by 2, 3, 4, and 6 (notice how much overlap there is).
10 only divides easily by 2 and 5. Common fractions like 1/4 or 1/3 now require decimals.
Basically, base 12 and base 60 make it significantly easier to think and work in common fractions.
It is also historically significant, as base 12 used to be more common than modern base 10. Our timekeeping system dates back to the ancient Babylonians, who worked in base 12. This influence is still felt in other places, such as the fact that eleven and twelve have unique names in many languages rather than following the same pattern as everything that comes after them.
The short explanation is that those numbers are more easily divided by a larger set of denominators. 24 is divisible by 2, 3, 4, 6, 8, and 12. 100 is divisble by 2, 5, 10, 25, and 50. 60 is divisible by 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, and 30.
Metric is great for scaling up and down ad infinitum, but it sucks for fractions. Fractions are easier for daily use without precision measuring equipment.
The units of time we use come from a bronze age civilisation that used base twelve instead of base ten. They'd count on their hands using the finger joints of one for single digits, and then the joints of the other for multiples.
Sunwise, as it was based on the movement of the sun during day (in the Northern hemisphere). As watch faces were modelled after sundials, sunwise and clockwise describe the same direction.
Turnwise is a word invented by Pratchett for a book, but it's clearly based on sunwise. He also used widdershins in his book, which is indeed the unmodified antonym to sunwise.
Not just any book. The discworld series. It's the direction the disc rotates! He has so many easy to miss spots of genius. Amongst many easy to see spots of genius
Was it Name of the Wind or Wise Man's Fear? I just read both of those and I remember looking up one of the words and going down a Wikipedia rabbit hole.
Imagine you're in the Northern Hemisphere and you face east toward the rising sun. Over the course of the day, the sun will seem to move to the south, and then set in the west. This forms a "sunwise" turn, which is what we now call "clockwise" because we made clocks in imitation of sundials.
Cardinal directions as references instead of left/right are often a better option when describing locations, more people should use them. It's not like it's hard to get an idea of where north is - even if you're a bit challenged on the spatial awareness front basically everyone these days has a phone that will easily tell you this.
To your second question, the direction of clockwise is mostly influenced by sundials. In the northern hemisphere the shadows move in a clockwise direction, and so the early clocks made in the northern hemisphere mimicked that. In the southern hemisphere it's naturally reversed, but because so much of that hemisphere is either empty ocean or colonized lands, the clocks move in the same direction. Bolivia had a sort of flash in the pan moment in the news about a decade back for reversing their clock direction on a big central clock (think like big ben) as a way of staking their independence from a colonial past.
On the first question, I have no idea. But in Sweden they use terms that translates to "with the sun" and "against the sun" but I don't remember what they are without googling it.
In czech, we have a phrase "jak sa kráje chleba" (same way as a bread is sliced). Problem is, that (at least in my social group) nobody knows, wether it means clockwise or anticlockwise, as everybody slices the bread differently.
I don't have an answer for the original question, but what about just saying rotate right/left?
I mean, if I imagine a circle rolling on a flat surface, rotating right means the rotation that rolls the circle right (so clockwise rotation), and rotating left would be the opposite; where the circle rolls left.
Honestly the hardest concept for me to grasp in organic chemistry was left vs right chirality. I could understand why they were different, but fuck me if i could ever consistently identify them.
What if the wheel is fixed to a frame and it moves a sheet above it like a conveyor system? Is the frame of reference the direction the sheet moves or is it how the wheel moves against the sheet? What if the sheet is below it like a pasta machine or sheet metal former? That being said, "right tightly, lefty loosey" has certainly prevailed
