Thanks for Connor Nieman's letter headlined "Finding resources." I assume his parents have already discovered Leonardo da Vinci? And do they know about Utah’s own Leonardo Museum in Salt Lake City? By the way, the 500th anniversary of da Vinci’s death is May 2, 2019.
Many have speculated on Leonardo’s mental wiring — and where he might be on various neuro-mental spectrums. A full discussion is in "Leonardo’s Brain" by physician Leonard Shlain. A great new biography is "Leonardo da Vinci" by Walter Isaacson.
There’s an enormous amount to learn and like about Leonardo da Vinci.
