THE NEW WAY vs Old ways​
Some old is more interesting. Simple and work .
Like CNC vs manual equipment. Or fastest 8 spindle automatic screw machine upto 50 parts in minute


When look at like a new engine vs the Old engines the both do same job.
So say the internal combustion hit peck in WW2

What is your view point?

Someone will have made or demonstrate an astrolabe... (or whatever!). Next.
Or
The use of a plumb bob and square to make a level..
5000 years ago the use light - lines of sight - From stick to stick - to make straight lines (lines of sight) when they didn't understand light and eyes and thought the eyes projected beams to see. E.g. many temples and other monuments were accurately aligned to sun, stars, etc.
Fascinating!

Thank you

I have use theodolite on dry land. Looks interesting to look at the sextant and astrolabe.

But internet on some post will totally different and others look same.

I know the will say on a rolling ship the Sextant is within 20 seconds. I this would closer to minutes. Then Navy best with a few reading can get within 3 notes.

Just think of building engines back in 1800's and 1900's using a sliderule or paper and pencil.

FYI I like when handheld calculators camd out any remember that day ?

I was talking to my son , he some old ways is more than looking at a cellphone or computer screen for reading books.
