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?

When you submitted the problem or some time thereafter, you also submitted (or will submit) your own solution. After that you can go to the link "Your Problems" and click on the "solution" link to your solution. At the bottom is a link to "Make the solution public". When you click on this link, the solution is made public, where visitors can click on "the solution".
Scholars can also see the solution queue, and after 2 or more days that the puzzle has been posted, the scholar can make the solution public. Obviously the solution must exist for this to happen, if the author has provided it.
