These are E-Z (Posted on 2018-06-25) Difficulty: 1 of 5
Three problems with one theme:

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?

Looking over the allowable abilities of the various levels of membership, I see you need to be at least an Apprentice to be able to post your own solution as the official solution. After you have three puzzles published on the site, the next day the system should make you an Apprentice and you will see a solution-publishing button on the page that allows you to edit the solution. We see that you do indeed have puzzles in the queue that, when published, will make you an Apprentice.
