Leonardo da Vinci’s experiments explored gravity as a form of acceleration
I may be missing something here, but there's a conceptual leap from "the acceleration produced by gravitational force" to "gravity as a form of acceleration".Da Vinci certainly appears to be exploring the former. The latter was Einstein's great insight. I don't see much in the article to persuade me that da Vinci was equating gravity and acceleration in the way Einstein did, and so the title seems a little too suggestive.
