No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Was there an alternative adjective to "clockwise" other than "the rotation you take around left hand"?

Also, how did all watch companies around the world agree on what the direction of "clockwise" is?

"Sunwise", and for the exact same reason.

Clocks go clockwise because their predecessors did. What were their predecessors?

Sundials.

How does the shadow go around a sundial? Well, sunwise, of course.

Counterclockwise, as said in another comment, was "widdershins", from a Middle Low German phrase meaning "against the way".

I am trying to picture it, but I think the sunwise convention only works in the Northern hemisphere.

[–] Auk@kbin.social 0 points 1 year ago (1 children)

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.

And if I'm thinking about this correctly, people between ~20N and ~20S latitudes will have it reverse throughout the year and and sometimes be a straight line.

Wait, it's all anglo-centric?

A guy I know owns this clock, which basically proves that everything in life is pointless and arbitrary:

[–] rm_dash_r_star@lemm.ee 0 points 1 year ago (1 children)

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.

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.

[–] Thann@lemmy.ml 0 points 1 year ago (1 children)

does that mean that "clockwise" in the southern hemisphere is backwards?

[–] aesopjah@lemm.ee -1 points 1 year ago (1 children)

No, because the earth is still rotating the same direction in the southern hemisphere

I read this article and I'm more confused now lol
https://en.wikipedia.org/wiki/Sundial#In_the_Southern_Hemisphere

EDIT: The last sentience sums it up well tho:

On horizontal northern-hemisphere sundials, and on vertical southern-hemisphere ones, the hour marks run clockwise.

[–] aesopjah@lemm.ee -1 points 1 year ago

Well well, learn something new everyday.

Pretty weird to think about. And about them having to either face their relevant poles or the equator for them to work equivalently
