The trace embedding lemma

You probably think you have seen an introductory talk on knot concordance before. But perhaps you have not seen an entire talk on the very first paragraph of the very first paper on knot concordance. The paragraph in question contains an observation now called the trace embedding lemma. In this talk, I will observe that the trace embedding lemma is great, especially for doing things that are not knot concordance.
