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." |
