The periodic table of the chemical elements is found decorating the walls of ... He described main shells and subshells with quantum numbers related to an electron’s energy and angular momentum.

Without spin, the entire periodic table of elements would come crashing down, and all of chemistry would go with it. In fact, there wouldn't be any molecules at all.

In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The ...

If the spinning were to stop, the angular momentum of every object on Earth would rip the surface apart, resulting in a really, really bad day. "This is just a thought experiment," said James ...
