Gallery : The shape of Planet Earth
1. Introduction The shape of the Earth has intrigued scientists throughout history. The general acceptance of the fact that the Earth is round came about in the first century A.D., although Pythagoras had already postulated a spherical Earth 600 years earlier. The flat Earth concept resurfaced now and again in the Middle Ages, sometimes on religous grounds, but it is safe to say that mankind has known for 2000 years that we live on a sphere. We know also that it is not a perfect sphere: the diameter from pole to pole is shorter than the diameter at the equator. The theoretical shape of the Earth has been studied by mathematicians over the past 4 centuries (although the interest has waned the last 40 years or so). It was Isaac Newton who first claimed that the Earth is not spherical, but "oval". In what follows we will discuss the theoretical shapes the Earth could take at a higher angular momentum, through the milestone discoveries of Colin MacLaurin, Carl Jacobi, and Henri Poincaré. 2.

The Mysterious Moeraki Boulders
If you go down to Koekohe beach in New Zealand you can be sure of a big surprise. In front of you, scattered like enormous marbles from some long abandoned game between giants, are hundreds of giant spherical rocks. Or are they the egg shells of sea-born dragons? Some are isolated but may occur in clusters. Many of the Moeraki boulders give the impression of being completely spherical – and they almost are. They do, however, tend to form early on in the history of the deposited sediment – it is thought they occur before the rest hardens in to rock. What is significant about these concretions is their size. The material responsible for their concretion is a carbonate mineral called calcite. There are large cracks on the boulders and these are known as septaria. The Moeraki boulders date from the Paleocene epoch which translates as the early recent. As you can imagine, there are many Māori legends concerning these hollow boulders.
