Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.
- The red ring is "behind" the yellow.
- The yellow ring is "behind" the blue.
- The blue ring is "behind" the red.
Still, while none is intertwined with another, it is impossible to pull them apart.
Is this a paradox?
Can this really be built?
(In reply to re(2): String theory
There's a trick to submitting problems with pictures in them. And that is:
You just submit the problem, without the picture, then you email Levik (there are various places you can find his email address... I'll leave that to you), tell him what problem it goes with, then he'll take care of the rest. I look forward to seeing your problem with pictures!
