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
Comment on How did people refer to clockwise movement before the invention of the clock?

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.

Rotating right/left as measured from the top or the bottom changes the rotation.

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.

What do you mean by that?

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.
