I have no synesthesia of any kind. I do have the ability to see some things "in my mind's eye", so I am not completely aphantastic, but with nowhere near the detail and vividness that my brother describes. I tend to rely on my auditory memory more than my visual memory, so my working memory is worse in noisy environments. On Sat, Sep 14, 2019 at 8:22 AM Henry Baker <hbaker1@pipeline.com> wrote:
Is it just me, or do others on this list experience numbers, formulae, etc., with more senses than just eyesight?
For example, I find formulae that have polarity -- e.g., determinants -- to feel "sharp" and/or have a sharp taste, whereas formulae that are non-negative to have a rounded shape and/or have a smooth taste. Thus, a squared determinant loses its sharpness.
By analogy, quadratic residues feel "smoother" than do non-residues.
Perhaps these feelings come from formulae such as:
abs(x)^2 = x^2
(abs(x) has a *sharp* edge at x=0, whereas abs(x)^2=x^2 does not.)
Perhaps numbers & formulae could also come with *sound effects* ?
