Shen Kuo · Science
How a disgraced official, jotting whatever caught his eye, turned the humble Chinese notebook (<em>biji</em>) into an instrument of science - more than five hundred observations spanning astronomy, geology, printing, magnetism, mathematics, and medicine, held together by one restless, watching mind.

Explain why the form itself mattered.
Leads to Leonardo da Vinci.
