Recently I discovered an online article -- "Bob Grumman’s mathematical universe: somewhere, minutely, a widening" by mathematician-poet Sarah Glaz) at Synapse International, an international visual poetry gathering, co-edited by Philip Davenport and karl kempton) that celebrates the work of math visual-poet Bob Grumman (1941-2015).. When I visited the article by Glaz, I also found several other articles that celebrated Grumman -- found here at this link for Issue 7, January 2024.
Below I post two of Grumman's Mathemaku -- visual poems that involve mathematical symbols and the brevity of Haiku; one of them is found in the article by Glaz mentioned above and the second is found here (along with others) in an article by karl kempton.
