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

The Killer Whale or ORCA as they are commonly called, inhabits all of the Worldâs oceans, preferring the coastal waters near shore in the cooler regions of the planet. Male Killer Whales are larger then the female of the species and can be distinguished easily by the shape of the whales dorsal fin. The dorsal fin of the male Killer Whale is significantly larger and is shaped more triangular then the femaleâs.
