Are Great Circle Tracks Curved ? - PeterB - 04-22-2022

Check out the attached illustration and decide for yourself.

Actually all tracks on the surface of a sphere must be curved in some sense or they would not stay in contact with the surface at all, but a great circle is about as straight a track as you can get while staying on the sphere.  It is all a matter of changing  your perspective.

Once again I don't see great circles taught this way elsewhere.  No wonder people find them confusing.

Simple stuff, I know. The applied math guys are probably rolling thier eyes, but this helped me "get it."
