Isaacson distills Leonardo's approach to studying any phenomenon into a repeatable loop: repeat the observation many times, vary the conditions, draw what you see, ask 'why' not just 'what,' and connect the pattern to another domain. This is not a hobbyist's curiosity — it is a research protocol disguised as wonder, and it is why a painter's notebooks outpaced physicians' anatomies and engineers' flight studies.
