Leonardo da Vinci: Study with desire!

Study without desire spoils the memory, and it retains nothing that it takes in.

Leonardo da Vinci

Leonardo di ser Piero da Vinci (Vinci, Italy, April 15, 1452 - Amboise, France, May 2, 1519, Old Style) was an Italian Renaissance polymath: painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer. His genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination".
