Field notes
Navigation divides the material into five chapters, including a section on the Yonsei 101 analog computer and a 220-volt chronology labeled 1973–2005. The visible register lists milestones from Han’s 1943 graduation through his 2017 designation as an inaugural science-and-technology honoree.
