Eratosthenes and Us, It Just Keeps Going and Going and Going...
Abstract
We decided to duplicate Eratosthenes' measurement of the size of the Earth. Here we relate our experience the second time we did the project in 1998. This year was unique in that we were funded by a NASA IDEAS (Initiative to Develop Education through Astronomy and Space Science) grant to support curriculum development and a teachers' workshop.
