Hero of Alexandria’s Automatic Theatre as a Mechanical Sequence Engine

תוכן האובייקטים עצמם כתוב באנגלית ועדיין לא תורגם.

תקופה ומקור

Alexandria, first century CE, in the conventional chronology of Hero’s work; surviving manuscripts are later copies

מה הוא נבנה לעשות

To produce a predetermined dramatic sequence - doors, figures, sound, flame, stage movement - from a single descending weight.

כיצד המנגנון פועל

The causal order of events is embodied in the routing and winding of cords and in the geometry of drums and axles. The architecture separates four functions: stored potential energy, a rate regulator, a physical program carrier, and effectors.

קלט

The displacement of a descending drive mass.

טרנספורמציה

A winding law on a drum, read by followers, pegs, valves and secondary cords; delays come from travel length, vessel filling, siphon thresholds and deliberately inserted slack.

פלט

An ordered vector of stage events, in a fixed sequence, at fixed intervals.

מה מבוסס בראיות

מבוסס: הממצא או התיעוד נושאים זאת במישרין.

מה הוא מדגים

That an order of events can be stored in a shape. Calling the cord routing a program is a defensible functional description and implies neither symbolic software nor arbitrary programmability.
