This includes navigational systems, which means having an intricate understanding of how and why longitude and latitude can only be derived for spherical objects.

All those longitude and latitude readings, can ONLY be assigned correctly on something

spherical

of a

precise, and unvarying circumference.

I got my science from four years in 5 math systems.

The first math system is all Base 10 mathematics through calculus 3.

The rest of that four years were spent learning every single characteristic of

electromagnetic forces and gravitational forces, why they exist, how they are calculated then verified with which instruments,

and then several years working in the radar, microwave, and radio business.
