| Thus, what looks to us like a sphere of scientific knowledge | more accurately should be represented as the inside of a highly | irregular and spiky object, like a pincushion or porcupine, with | very sharp extensions in certain directions, and virtually no | knowledge in immediately adjacent areas. If our intellectual | gaze could shift slightly, it would alter each quill's direction, | and suddenly our entire reality would change. | | Herbert J.

Lipton • The Art Of Math https://rjlipton.wordpress.com/2020/11/12/the-art-of-math/ Dear Lyle, Thanks for the link to the Wikipedia article on Cactus Graphs ( https://en.wikipedia.org/wiki/Cactus_graph ), which I found surprisingly good for that venue. I was pleased to see it mentioned the role my own first teacher in graph theory, Frank Harary ( https://en.wikipedia.org/wiki/Frank_Harary ), played in the history of cactus graphs. Frank co-authored Graphical Enumeration and many papers with Ed Palmer, my second teacher in graph theory and later my advisor in grad school. Synchronicity being what it is, one the jobs I worked on between my undergrad decade and my first crack at grad school was scanning and measuring particle interactions on bubble-chamber filmstrips in a high-energy physics lab, so I got a gadshillion gammas burned in my brain from that time.
