In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles, and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution: it arises when a particle executes a rotating or twisting trajectory. The existence of spin angu

Orcinus translates to âof the kingdom of the dead,â and orca refers to a kind of whale. What we now know is that not all orcas prey on other cetaceans. Some populations specialize on fish, some on seals, some on sharks and rays, and some are generalists and eat many different things!
