  The unique and beautiful character of certain mathematical results and proofs
is often considered one of the most gratifying aspects of engaging with
mathematics. We study whether this perception of mathematical arguments having
an intrinsic 'character' is subjective or universal -- this was done by having
test subjects with varying degrees of mathematical experience match
mathematical arguments with paintings and music: 'does this proof feel more
like Bach or Schubert?' The results suggest that such a universal connection
indeed exists.
