Geodesy is a field of study that deals with the measurement and representation of the Earth, and it all started when a clever human named Eratosthenes discovered that you could measure the circumference of the Earth by looking down a well. Over time, the field of geodesy has expanded and evolved dramatically, and NASA uses technology like radio telescopes, ground surveys, and satellites to contribute!

FreeRice is a non-profit website run by the United Nations World Food Programme.
- Provide education to everyone for free.
- Help end world hunger by providing rice to hungry people for free.
This is made possible by the generosity of the sponsors who advertise on this site.
Whether you are CEO of a large corporation or a street child in a poor country, improving your education can improve your life. It is a great investment in yourself.
Perhaps even greater is the investment your donated rice makes in hungry human beings, enabling them to function and be productive. Somewhere in the world, a person is eating rice that you helped provide.
