New finding from Antikythera MechanismBased onstatistical analysis of micro CT imaging of the more than 2,000-year-old Antikythera Mechanism, we show unexpected evidence establishing a lunar calendar with Egyptian civil-calendar month-names circa 100 B.C. This finding displaces a century-long presumption of a 365-day solar calendar on the Antikythera Mechanism with a 354-day lunar calendar and may inform a fundamental question of the number and type of calendars used in Ancient Egypt.

Well, yeah, obviously. ;^)
But does it tell TIME??........................
Oh well then, this is clearly within the capabilities of the Greeks of that day.
I had deep reservations about a calendar based on the Sun because that would be a ridiculous claim. :-)
His video updates stopped about a year ago, until this week when he posted another video announcing this paper, that he co-authored.
Kinda neat binge watching if you're so inclined.

The two key finds:
+ A pin and slot mechanism accounting for the moon’s elliptical orbit.
+ 26.5 x 2 = 53
A number of cultures used lunar calendars. Semitic ones come to mind.
Looks like one of those things on the door of a submarine that the sailors spin to bolt the door.
I think the technical term is Submarine Spinning Thing.
Ah! That explains it.
Any tool that gives you a better sense of when to duck can command any price!
The lunar cycle is closer to 29.53 days. A lot of moon phase clocks have gears with 59 teeth (as did the Antikythera mechanism) that closely approximate two lunations. The Gregorian calendar has a sidekick lunar calendar good to about one day in 8,000 years on average, which is even better than the Gregorian calendar’s approximation of the solar year (365 + 1/4 -1/100 + 1/400 = 365.2425), which is only good to about one day in 3000 years. The lunar calendar is used with the Gregorian Calendar to calculate the date of Easter.
It does, but it’s so heavy the wristband keeps breaking.
It’s actually the first artificial heart... a little clunky but it was a start.
That’s where I ran into it, couldn’t stand the video, and looked for the original research.
There’s a bunch of vids pirated from documentaries about the replication efforts by watchmaker and such, going back at least twelve years.
What powered the thing? A wind-up coil spring was about 1500 years in the future................
The synodic month (which is the familiar one) is 29.53, the sidereal month is 27.something. :^)
