   Format: MarkdownI see that [[Ben Webster]] was so kind to start [[knot invariant]]. That nicely supplies linkes for Bruce's recent [[Chern-Simons theory]]

   Format: MarkdownItexThat was a long while ago. I have reordered the list of invariants. The simpler ones are at the top with deeper ones further down. (I had not read the blog entries by Ben. I wonder what he thinks now? I agree with Andrew, the Lab is en excellent way of not loosing the bits of paper!)
