Just received my copies of Exploring the Invisible, a much-expanded and updated second edition. More than fifteen years ago I worked on the first edition (left) as assistant to my mentor, Joel Avirom, and so I was very happy when Princeton University Press approved my “homage” version of the cover (right). The image of a petri dish (Objectivity [tentative]: Sound to Shape by Nurit Bar Shai) seems eerily prescient, though obviously Covid-19 was not on my mind nor author Lynn Gamwell’s when she suggested it!
