Title: Some one pease explain this!
Post by: qwerty1234 on February 26, 2011, 05:09:44 AM
how do you explain how a jet can start at one point on the earth, and if it keeps fyling straight it will eventually go back to the same spot. Because if the earth was flat it would never return?

When has a jet ever started at one point on the earth, flown in a straight line and reached the same point from where it started?

I've never flown a jet, but I'm fairly certian that you have to turn on occasion when flying straight.

In 1986. Actually, they had to evade storms and such, so it wasn't technically a straight line...

I still see no straight lines ever used.

probably never. But you know what he means, and before you start going on about how RE's surface is curved, straight lines are great circles in spherical geometries

Aeroplanes are designed with one wing shorter than the other, causing them to turn slightly over long distances.

Not really.
Quote from: http://en.wikipedia.org/wiki/Great_circle
A great circle, also known as a Riemannian circle, of a sphere is the intersection of the sphere and a plane which passes through the center point of the sphere, as distinct from a small circle. Any diameter of any great circle coincides with a diameter of the sphere, and therefore all great circles have the same circumference as each other, and have the same center as the sphere. A great circle is the largest circle that can be drawn on any given sphere. Every circle in Euclidean space is a great circle of exactly one sphere.

 Do you work for Gruman or Boeing?

I would never work for the conspiracy!

Replying with a fallacy only tends to undermine your position

Ehh I think he's pretty much winging it, but either way it's over your head.

You do know that the great circle is the equivalent to a straight line on elliptical geometry, right? Nowhere in that post did you show otherwise? on the spherical 2-D plane, no other line is straighter. It is a geodesic. This is the third time this week someone has tried to tell me a very standard part of geometry is incorrect. http://en.wikipedia.org/wiki/Geodesic

Actually, I was just pointing out that a great circle is a certain type of circle on a sphere.  Not all circles on a sphere are great circles.

ok. and that's why I started off by saying great circles. I never said circles

Aeroplanes are designed with one wing shorter than the other, causing them to turn slightly over long distances.

To add to that, there is a small hamster running the wheel on the tip of the wing that's shorter, causing that side to be heavier. The hamster wheel also acts as a gyroscope for stabilization of the flight.

I don't see any need for a hamster wheel when simple weights would suffice.
