At my request, Akira Tonomura sent me a copy (shown below) of a calligraphic scroll displayed at the Hitachi Research Facility. It was mentioned in his essay about Professor Yang Chen-Ning, who had mentored him. I read it because I had been a colleague of Frank Yang's at Stony Brook, and had been a student of "TD" Lee's at Columbia when Lee and Yang won the Nobel Prize.
The proverb in the calligraphy could be considered the motif of my essay at http://uniso.karleklund.net/. That essay was inspired by Lee's and Yang's attitude toward statistical mechanics and mathematical physics, two of the subjects I heard "TD" lecture on in the late '50s.
