    Here’s an old video Not Knot (in 2 parts), including some early computer graphics and sci-fi sound effects:

    I was just thinking about know mathmatics yesterday, while trying to un-knot some Christmas tree lights. Apparently anything but a pefectly strait line is on its way to becoming a knot. Our super strings must have formed the knot from hell.
    And yet, folding (which is what protiens do) is a lot more complex than a knot. Nature is crazy for details.

    Is it wrong that the first thing that came to mind when I saw this post was Clive Barker’s short story, “The Inhuman Condition”? Beware what comes of untangling knots….

    “Strictly speaking, then, the string in Raymer and Smith’s box was never knotted.”

    I can think of no clearer statement that mathematicians do not bother themselves with reality.

    If Loop Quantum Gravitation is correct, everything is made of knots.

    Isn’t loop Q-G just Knotted Super Strings? Is there a way to test Q-G theory…yet?

    Not exactly, Registrado. LQG says that spin networks have equivalence classes under diffeomorphisms on a 3-manifold that are isomorphic to knots, but all that means is that fermions aren’t allowed to occupy the same place and state, per the usual Pauli exclusion principle, and when you view interactions from a different frame of reference, it has the same connectivity.

    I loved knot theory as an undergrad, but I’m glad I didn’t go into it, like, it would be less valuable than a history degree.
