David Corfield highlights two articles by Samson Abramsky: one on Temperley-Lieb algebras and the other on concurrency.

The concurrency article, *What are the fundamental structures of concurrency? We still don’t know!*, discusses the profusion of formalisms for representing concurrency. Abramsky passes on the following anecdote:
