Quote: "Several people here seem to be recruiting for the Flat Earth Society."
It can easily be shown that the earth is flat.
A circle consists of a series of points linked to each other, each point being infinitesimally small.
An infinitesimally small point can only be defined by the slope at that point(Differential Calculus)
Lim dy/dx
dx->0
Clearly the slope is a straight line in the xy plane
i.e. any point on a circle is essentially "flat"
Any point on any Line of latitude or longitude on the earths surface is flat. (The infinitesimally small tile you are standing or sitting on right now is flat, to cite a practical example)
Since a circle is essentially a straight line that has no end,
the circle is a straight line.
Therefore by definition, the earth which is an infinitely large set of straight lines of latitude and longitude is flat.
(In case you are wondering why I consider the set of lines of latitude and longitude to be infinitely large, it because any point on any line is infinitesimally small)
The earth just appears to be spherical when looked at by the naked eye.(Maybe because our eyeballs are spherical and they distort all images that fall on the retina)
If you look at the earth with a mathematical eye it is clearly flat.
First impressions, by the naked eye can be deceiving, as you must have noticed after one month with your new date. Don't trust your naked eyes. Mathemtical proofs are more accurate.
You can manipualte any mathematical fact to prove anything.
And History is testament to the fact that math arguments can extend to the end of time, and even beyond, to infinity.
MORAL OF THE STORY:
Whenever you read a mathematical statement, question everything, take nothing at face value, while trying to hang on to your sanity.
