The Universal Mind

Leonardo da Vinci was not merely a painter who dabbled in science — he was a systematic investigator who used art and science as twin tools for understanding the world. His notebooks contain over 7,000 pages of drawings, diagrams, and observations covering anatomy, engineering, optics, botany, and fluid dynamics.

Leonardo's anatomical drawings, based on more than thirty human dissections, were centuries ahead of published medical knowledge. He mapped the heart's valves and traced the flow of blood with a precision that the science of his day could not explain or confirm.
