Rebuilding the 2000-year-old Antikythera as a watch

NVP3D: The oldest known mechanism to use clockwork gears, called the
Antikythera after the place it was discovered, was found in an ancient
Greek shipwreck more than a hundred years ago. The device, of which only
82 badly corroded fragments remain, not only predicted solar eclipses
but also organized the calendar in the four-year cycles of the Olympiad,
forerunner of the modern Olympic Games. The watchmaker Hublot has now
miniaturized the Antikythera from the size of a shoebox to something
that you can wear on your wrist. This version also tells the time.

None of you accept the basis for predicting astronomical events within
the 4 year calendar system which formats the annual cycles as
continuous rotations of the Earth or as the creators of the
Antikythera mechanism would have understood it as a progression of
days.At least the current engineering guys are practical when it comes
to timekeeping,they don't have to consider the applications to
astronomy nor the principles derived from astronomy hence their
irritation with the 'leap second' indulgences which arose a few
decades ago by people who never understood what leap corrections
amounted to.

Anything based on a 4 year cycle is based on 4 orbital circuits of the
Earth around the Sun and the number of days/rotations that correspond
to these circuits.It is not your stubborn refusal to accept 1461
rotations in 1461 days but inability of people to feel shock at the
attempted imbalance of 1465 rotations in 1461 days that is truly
astonishing.The most visible sign of self-loathing is not attacks
against me as a substitute for ignoring the actual principles which
keep rotations in proportion to an orbital cycle but rather the sin of
silence,people do actually know what is correct and fail to act
whether you know it or not.
