Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

In a controversial experiment, physicists investigated whether we could harness the Earth's rotational energy to generate electricity.

Earth's spin is constant, but the speed depends on ... If we move halfway up the globe to 45 degrees in latitude (either north or south), you calculate the speed by using the cosine (a ...

Why does the Earth spin? Sara H., age 5, New Paltz, New York A globe was the first thing I ever bought with my own money. I was maybe 5 years old, and I was really excited to take it home.

While Agnew's study suggests we have more time before facing this worrying unknown, it's worth noting that Earth's spin is very difficult to predict, and the new study is not necessarily a ...
