As someone who spent a decade doing precision metrology with optical devices... there isn't a way to correctly measure that part with the precision they indicate in the measured values.
- kryptiskt 2y agoThe measurements were done on X-ray images, not optical.
- qtplatypus 2y agoIf I recall the precision is limited to by the wavelength of the light being used. If they are using X-Rays in the 0.01 nm to 10 nm range wouldn't that give them more precision then optical light in the 380 nm to 700 nm range?
- dsalfdslfdsa 2y agoIt's not that precise. As for the method: https://bhi.co.uk/wp-content/uploads/2020/12/BHI-Antikythera-Mechanism-Evidence-of-a-Lunar-Calendar.pdf https://bhi.co.uk/wp-content/uploads/2020/12/BHI-Antikythera...
- dekhn 2y agoIf you're in optical measurement and it should be around 200nm (rayleigh criterion, wavelength dependent), am I missing something? Obviously, that's just angular resolution, not measurement precision, so I'm guessing I'm missing some detail.
