Lynn Gamwell’s Exploring the Invisible: Art, Science, and the Spiritual (Princeton University Press) is a revised and expanded second edition to the 2005 original, as well as a companion to Gamwell’s Mathematics + Art, a book I designed in 2016. I worked on the first edition of Exploring as assistant to designer Joel Avirom — who knew I’d have the opportunity to redesign it 15 years later! The book officially pubs in March but I got a peek at an advance copy courtesy of the author.
