Re: Technology related anachronisms on TV and in films etc.
My theory about why right hand threads are most common is this.
The first threads would have been cut freehand on a lathe. For a right handed person it's normal to have the lathe head stock on the left. Cuts are made towards the headstock and that produces a right hand thread.
If you watch the TV series "Wish Me Luck" there's a scene where a radio operator is asked to repair a set. She picks up a screwdriver and pretends to undo some screws. but she rotates the screwdriver clockwise.
