Listas de Leonardo da Vinci

Leonardo adorava fazer listas de coisas que tinha para fazer, assim como de coisas que desejava aprender. Nestas podemos encontrar de tudo, demonstrando a sua mais importante competência: uma infinita curiosidade.

. "Get the master of arithmetic to show you how to square a triangle…"
. "Ask Benedetto Protinari by what means they walk on ice in Flanders…"
. "Get a master of hydraulics to tell you how to repair a lock, canal and mill in the Lombard manner…"
. "Describe the tongue of the woodpecker” [1]
. "Get the measurement of the sun promised me by Maestro Giovanni Francese, the Frenchman."
Sobre a língua do pica-pau, deixo a imagem do Earth Touch e o texto de Isaacson, escrito como Coda do livro "Leonardo da Vinci" (2017), sobre o qual ainda aqui farei uma resenha alongada

[1] Describe the tongue of the woodpecker
"The tongue of a woodpecker can extend more than three times the length of its bill. When not in use, it retracts into the skull and its cartilage-like structure continues past the jaw to wrap around the bird’s head and then curve down to its nostril. In addition to digging out grubs from a tree, the long tongue protects the woodpecker’s brain. When the bird smashes its beak repeatedly into tree bark, the force exerted on its head is ten times what would kill a human. But its bizarre tongue and supporting structure act as a cushion, shielding the brain from shock.
There is no reason you actually need to know any of this. It is information that has no real utility for your life, just as it had none for Leonardo. But I thought maybe, after reading this book, that you, like Leonardo, who one day put “Describe the tongue of the woodpecker” on one of his eclectic and oddly inspiring to-do lists, would want to know. Just out of curiosity. Pure curiosity.”
