Thank you very much for your work. Very nice explanation.

Very cool so if you take an orange and no matter how you slice through the orange , if the blade goes through the exact center of the orange . This is a great circle. Old dog learning even older tricks. 👍

It's flat.

[@duantorruellas716]

Sure every thing in nature is round , cells , Cherry's , oranges , planets , in space water is round . But some think the earth is the only thing flat in space like a Borg cube. Oh wait plant cells are square , maybe we live on a plant in space.

Navigation works precisely because we understand the Earth's shape, we know distances etc..
We make use of the knowledge of the correct figure of the Earth for the purposes of navigation. This is how our ancestors were able to travel to the other side of the world (and back to the original location) without the modern technology we have today. The American Practical Navigator, first published in 1802, was billed as the "epitome of navigation" by its original author, Nathaniel Bowditch. The text has evolved with the advances in navigation practices since that first issue and continues to serve as a valuable reference for marine navigation in the modern day.
The publication describes in detail the principles and factors of navigation, including piloting, electronic navigation, celestial navigation, mathematics, safety, oceanography and meterology. It also contains various tables used in typical navigational calculations and solutions, including the formulas used to derive the tabular data.
