    Are your math visualizations in color? Mine are all black-and-white, presumably in imitation of diagrams in textbooks. Just realized from this @St_Rev tweet that I may be missing an important tool. (Does synesthesia play a role here?)https://twitter.com/St_Rev/status/1189949262307766272?s=20 …

    b) Internal representations don't necessarily transfer. If I mostly do homological algebra with kinesthetic representations, and you think syntactically, I'm not sure what I can tell you. "uh so this is like a string of p-1 red beads and...wait the _string_ is red, and..."

        Mine are spatial but mostly not actually visual. So probably more kinesthetic than properly visual. (I have more thoughts about the original point but I haven't decided how to express them usefully yet.)

        Yes, this mathematical sense that is vague-ish shapes that aren't quite visual and aren't quite kinesthetic but sort of both is extremely interesting. @michael_nielsen has written some interesting things about it somewhere

        Slightly embarassed to say that the 'colors' in this case are actually 'alpha' and 'beta', although I did make them blue and red on talk slides. Could also call them 'textures', 'directions', 'musical notes' or 'scents'

        That does sound like synesthesia! @_awbery_ sees integers all in different colors and has sound synesthesia as well

        (1/2) mine are b/w, look like textbook diagrams. but also simple and fragmentary and concentrated in a small "virtual fovea" that "saccades" around (i think most/all of my mental imagery is that way). not sure what % of it actually adds value by using spatial cognition...

        (2/2) ...and when i'm trying to use it that i often find the lack of >3D frustrating and limiting. perhaps more often, my images are more like ideographs, a symbol system where something like https://en.wikipedia.org/wiki/Injective_function#/media/File:Surjection.svg … is the word for "surjection" etc

        Cool! Colors? Moving or static? Under your control or independent?

        I think I deal a lot with something like felt senses or emotional schema or something. A lot of reasoning comes from connections appearing there for me. I visualize, but that's not the main driver of insight I don't think.

        https://www.amazon.com/Emotions-Bodies-Vital-Abstract-Thought/dp/1138565849 … This book argues that math is driven by brain activity whose cognitive correlates are probably going to be pretty difficult to access phenomenologically
