The Antikythera Mechanism as a Temporal Astronomical State Engine

תוכן האובייקטים עצמם כתוב באנגלית ועדיין לא תורגם.

תקופה ומקור
Hellenistic Greece, second to first century BCE; recovered from the Antikythera wreck
מה הוא נבנה לעשות
To turn a manually supplied amount of elapsed time into the coordinated astronomical and calendrical state that time implies - lunar phase and age, the Metonic and Callippic calendars, the Saros and Exeligmos eclipse cycles, the games cycle, and, on the lost front, the Sun, Moon and five known planets.
כיצד המנגנון פועל
Rational approximations to astronomical period relations are realised as gear ratios. Compound trains, a pin-and-slot pair producing lunar anomaly, differential kinematics and spiral indexing carry one input shaft into many simultaneous outputs, each advancing at its own rate from a shared drive.
קלט
One manually turned shaft carrying elapsed time.
טרנספורמציה
Period relations approximated as tooth-count ratios, composed through compound gear trains; a pin-and-slot pair introduces the lunar anomaly, and spiral dials index cycles longer than one revolution.
פלט
Several astronomical and calendrical phases displayed at once, each on its own dial and each with its own period and epoch.
מה מבוסס בראיות
מבוסס: הממצא או התיעוד נושאים זאת במישרין.
מה הוא מדגים
That a fixed physical arrangement can hold many periodic relations at once and evaluate all of them from a single input - and that the surviving rear mechanisms are established while the planetary front remains reconstruction, which is a distinction the object itself forces a reader to keep.
