Jay Owens argues that dust is a lot more interesting than we think, and we ought to pay more attention to it.

Jay has spent years researching dust, and produces a popular newsletter on the subject. In this fascinating Four Thought, recorded at the Design Museum in London, she shares some stories from the field of dust research that up until now have only been known to other 'dust people', as she calls her fellow dust researchers.
