oblateness

Because the rotation of the Earth forces mass near the equator against gravity, the Earth is a shape known as an oblate spheroid, a shape mathematically equivalent to taking a sphere and scaling it down on one axis. Many things in science and engineering have to take into account the true...

Hi. I'm an engineer and try to educate Flat Earthers, sometimes with a little success :) According to geodetic measurments the shape of the earth is not exactly a sphere, but slightly bulged at the equator - oblate spheroid. Flat Earthers claim that this oblateness can not be seen on satellite...
