Given a sufficiently large earthquake, like the so-called Good Friday earthquake in Alaska in 1964, which had a magnitude of 8.6, the entire Earth actually vibrates. It is fairly intuitive that the ...

1.2 Mass of the Earth: Cavendish's Experiment to "Weigh the Earth" The next thing is to try to find out how much the Earth might weigh. This is much more difficult, and requires a very cunning ...

With this simple formula, Cavendish established the mass of the Earth using a very accurate balance beam by the following steps - ...

Because of this he knew about angles. At that time the concept of "angle" was still new and it was cast in terms of ratios in two different ways. Erastosthenes measured the sun angle on the longest ...

If the Earth were flat the "sun angle" would be the same everywhere. The sun is so far from the earth that the light "rays" from the sun are more or less parallel If the Earth is round then the "sun ...
