43. Asimov SCI-DOKU

This week’s Scientific American SCI-DOKU puzzle involves Isaac Asimov, whom I happened to meet years ago at a Mohonk Mountain House mystery weekend. He was very funny and personable with no lack of self-confidence, as his business card title below proves (personal info altered).

The photo is one I captured of him and his wife, Janet, while strolling through NY’s Central Park several years later. His response, after I sent him a print, was: “We’ve never seen ourselves from behind in this manner — and in such an affectionate pose, too. It seems to me that we should be an inspiration to sexagenarian lovers everywhere.”
