hello I wonder whether this puzzle is possible to solve.

if possible, what kind of thing should I learn to solve this?

the problem is make left one to right one without cut the rope only stretch and bending are allowed I found out this puzzle here->(www.ocf.berkeley.edu/~wwu/riddles/hard.shtml/)

from here to here

I wish this problem lead me to learn math intuitively.

    This puzzle can be found [here](http://www.ocf.berkeley.edu/~wwu/riddles/hard.shtml). It's labeled "topological rings".2012-11-15

    The puzzle description: "Imagine the object above in the figure to the left made from perfectly elastic material. Can you transform it so as to unlink the two rings as in the figure on the right? One possible way is to cut one ring, move the other ring through the gap, and rejoin the the first ring exactly as it was. That would be a legitimate topological transformation. However, it is also possible to transform the first shape into the second without any cutting, simply by manipulating the objects in the appropriate manner (stretching, bending, but not breaking). Can you see how to do it?"2012-11-15

    There's a nice diagram showing how this is done in Keith Devlin's *Mathematics: A New Golden Age*.2012-11-15
