1) Feynman, when pledging his engineering fraternity, was quizzed: why does a mirror reverse you right to left but not top to bottom?
2) Why is East found to the left on star maps?
3) Since a screw goes into a nut by turning to the right, clockwise (CW, "righty-tighty") should not a nut go into a screw turned to the left, CCW?

Thanks for the help

“Saving a solution here will not post it to the site. 

It will be stored in the system, awaiting for an administrator's approval. 

Once approved, it will show up on the site linked to the problem.

nor do I know how to change the (No Solution Yet, 3 Comments)”  

Thanks
