Does each language have "lefty loosey righty tighty"? (lemmy.world)

The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.

So does each language have a fun mnemonic?

Your thumb is an arrow pointing at where you want the screw to go. After you curl your fingers, your fingers are arrows showing the direction to turn the screw

We were taught a similar trick in physics - point your right-hand thumb in the direction that current (or electrons, same same) is travelling and the curling of your fingers shows the direction of the resultant magnetic field that the current creates.

I teach physics. A prof of mine taught me the right hand rule applies to right handed bolts. No accident they are named that. I teach this to students now. Maybe 1 in 10 like it. The rest prefer their old rhyme. Oh well. Can't say I didn't try
