These are E-Z (Posted on 2018-06-25)

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?
