The article examines the accuracy of the gear trains of the Antikythera Mechanism, an ancient Greek device that was possibly used as an astronomical calculator. The author analyzes the placement of the mechanism's gear teeth. Mathematical models of gear train accuracy are provided, with the author noting the standard deviations in the trains. Because of the gear errors present in the Mechanism, the author concludes that it was probably used more for display or education purposes than for actual…

Calculating the torque on the shafts of the Antikythera Mechanism to determine the location of the driving gear
TLDR
This paper tries to compute the transmission of torque from any of the mechanism’s gears to the rest of the gear-trains, to determine the best possible location of a driving gear or crown as the case may be.

Our current knowledge of the Antikythera Mechanism
The Antikythera Mechanism is the oldest known mechanical calculator. It was constructed around the second century bce and lost in a shipwreck very close to the small Greek island of Antikythera. The

The Antikythera Mechanism and the Public Face of Greek Science
From the outset two questions have dominated the study of the Antikythera Mechanism: what did it do? and what was it for? The first question, essentially the problem of reconstructing the Mechanism

TLDR
Two arithmetical models are presented here that explain the complete eclipse prediction scheme and imply a surprisingly early epoch for the Antikythera Mechanism.
Using Computation to Decode the First Known Computer
TLDR
Researchers have used many different kinds of software to analyze the structure and astronomical functions of the Antikythera mechanism's surviving fragments, which has an extraordinarily sophisticated mechanical design.
The Antikythera mechanism and the mechanical universe
How did our view of the Universe develop? By the mid-eighteenth century, a world view had developed of a system constrained by physical laws. These laws, if not entirely understood, showed regularity

Calendars with Olympiad display and eclipse prediction on the Antikythera Mechanism
TLDR
Though no month names on the Metonic calendar were previously known, all 12 months are identified, which are unexpectedly of Corinthian origin, and the cycles of human institutions with the celestial cycles embedded in the Mechanism’s gearwork are linked.
