i can appreciate the practicality of some knots. my primary admiration goes toward the beauty of symmetry and simplicity, however.

Solving Wolfgang Haken's Gordian knot is trivial and left as an easy exercise to the reader.

what's the problem? if it's a knot just fucking untie it. give me a physical knot, tied from a straight rope, and i'll untie it. it's not fucking rocket science.

apparently its highly non-trivial.

also i guess people are lazy at tying a real not or they have tried and realized applying formal simplifications to a physical object is tedious.
