Small Business owners are largely forgotten. Thats why I only focus on them. I have experience several members of my family file bankruptcy due to small business failures. I also I suffered through 2 destroyed businesses due to failure however, in my failings I have learned some of the secrets to success. (Who can say they know it all?)www.onlineuniversalwork.com

In São Tomé and Príncipe, the equator crosses the small Rolas Islet (Ilhéu das Rolas). There is also an equator monument to honor the portuguese geodesist and cartographer Gago Coutinho who demonstrated the equator’s passage in the islet. Check http://upload.wikimedia.org/wikipedia/commons/8/82/Equator_Sao_Tome.jpg to see the monument.

Man! I always believed the water draining thing. Especially after seeing it at that Inti Nan thing.

They also do another thing: at the equator, you're supposed to be able to balance a raw egg on a nail. If you manage to do it there you get this certificate. I was way to hung-over to manage. Fortunately I now know it was probably a fake as well!

That I couldn’t say! This page seems to list the offsets from WGS84 of loads of different datums (data?)

SAD69 is the South American Datum of 1969.

They won’t appear on Google Maps – I added them to the thumbnail simply to show where they are. See also this site: http://www.therealequator.com/intinan_museum.html

Where are the two points where WGS84 crosses SAD69?

Neat. I wasn’t aware that the different spheroid reference data do indeed have different equators.

When thinking about it, it seems unreasonable to expect them to have the same though

Very nice geonerd post, I had never heard of SAD69 before.

Haha Especially funny as the coriolis force is 0 at the equator anyway. So even if it were true, it wouldn’t work at the equator
