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

According to National Geographic, orcas are considered the largest species of the dolphin family. They weigh up to 6 tons (5,443 kilograms) and grow to 23 to 32 feet (7 to 9.7 meters).
