'Twas the night before Christmas 1802, and Thomas Young was conducting his now famous double-slit experiment. It was the first demonstration of the wave behaviour of visible light. Moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
All in all, the double-slit experiment has become a classic for its clarity in expressing the central puzzles of quantum mechanics.
Fast forward 220 years later, we still love puzzles!
The outcome of this double-slitherlink experiment may or may not be predictable. What we do know for sure is:
- Similar to the double-slit experiment, we start with a double path (one path in each slitherlink)
- If all is well, we end up seeing the light
- Basic slitherlink rules apply
If you feel like these slitherlinks are underconstrained, or just can't see what to do next: further instructions are hidden inside the grids.
In the puzzle text, feel and can't see are hints towards finding the hidden instructions in the grids.
