I love the colour green. I remember loving reading about and looking at photos of arrays of different types of green vegetables in encyclopaedias (yes, plural) when I was a kid.

#Ulam is visual culmination of my interest. Even growing up in a small town, ulam never seemed to pique my curiosity. Until I moved to #Perlis and there's a ton of restaurants here with an incredibly huge selection of ulam with vegetables I've never seen before.

I'm in ulam heaven. #Malaysia

Survey of Precursors Of Category Theory
• https://inquiryintoinquiry.com/2023/04/03/survey-of-precursors-of-category-theory-3/

A few years ago I began a sketch on the “Precursors of Category Theory”, tracing the continuities of the category concept from Aristotle, to Kant and Peirce, through Hilbert and Ackermann, to contemporary mathematical practice. A Survey of resources on the topic is given below, still very rough and incomplete, but perhaps a few will find it of use.
