Hello:
In geometry this came up a few times today with that equator problem. I figured that I would help with some more information for your reading pleasure…
1.) To Wikipedia
2.) Equatorial Bulge Physics Article
3.) Strange but True Scientific American Article
What are your thoughts? Do your own research. Did people (who traveled) actually believe at any point that the world was flat??? When was it proven?
Who cares about the “bulge” at the equator? What does that mean for us on earth, if anything?
Happy Tuesday,
Mrs. Corricelli
