How did people refer to clockwise movement before the invention of the clock?
How did people refer to clockwise movement before the invention of the clock?
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?
You're viewing a single thread.
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.
It works, but it's ambiguous. You have to specify which part you're referring to if you want to be sure you're understood.
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.
You have to specify which part you’re referring to
What do you mean by that?
Turning right, looking at the top of the clock, is different from turning right while looking at the bottom of the clock. And so on.
You're not entirely wrong, but the convention is to refer to the top of the wheel. But you could be looking at the wheel from the other side, which would change its direction from your perspective.
That's true, but saying clockwise/anticlockwise also works with fixed perspective, unless the thing itself has a fixed orientation. but if that's the case, left/right works the same.
No, it's an extra level of confusion. Clockwise/counterclockwise only has one axis of confusion (looking from front or behind) with one option being the obvious default. Left/right have this axis AND the axis of top/bottom for confusion. It's literally one bit more ambiguous.
No matter which direction a ball rolls, part of it moves to the right, and part to the left (either top right and bottom left, or vice versa). If you don't specify which part of the ball you're looking at, it could be either top or bottom, so the statement is ambiguous.
but without this information, clockwise and anticlockwise also ambigous.
No, they are well-defined. There is no missing information in "clockwise". There is missing information in "right".
There is no "top clockwise" or "bottom clockwise".
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
Seit das Deutsche Reich besteht, wird die Schraube nach rechts gedreht!
Rotating right/left as measured from the top or the bottom changes the rotation.
