In honor of Nathaniel Friedman, who passed away from COVID-19 on May 2, 2020, I have carved a wooden version of one of his beautiful stone sculptures. Nat was a pioneer in the mathematical art movement, a leader in organizing math art conferences, and an inspiration to many people. He created the journal, Hyperseeing, and founded the International Society of the Arts, Mathematics and Architecture (ISAMA). This sculpture is a genus 2 surface with a raised edge forming a figure 8 knot which goes around the two holes, but not through them. The line on the surface which forms the knot divides the surface into two disjoint regions, and the surface is orientable. The original block of cherry wood was 2"x6"x6" in size. I have two other blocks of wood which I plan to also carve into this ``Friedman Figure 8 Knot" design, one is Maple Ambrosia, and the other is Purpleheart.
