Spin (physics) discrete angular momenta despite having no orbital angular momentum. In some ways, spin is like a vector quantity; it has a definite magnitude, and it has a "direction" (but quantization makes this "direction" different from the direction of an ordinary vector). All elementary particles of a given kind have the same magnitude of spin angular momentum, which is indicated by assigning the particle a spin quantum number. The SI unit of spin is the (N·m·s) or (kg·m·s), just as with classical angular momentum. In practice, spin is given as a dimensionless spin quantum number by dividing the spin angular momentum
Madja-as most illustrious nobility in the whole island." Miguel de Loarca, who was among the first Spanish settlers in the Island, also made one of the earliest account about Panay and its people according to a Westerner's point of view. In June 1582, while he was in Arevalo (Iloilo), he wrote in his "Relacion de las Yslas Filipinas" the following observations: The island is the most fertile and well-provisioned of all the islands discovered, except the island of Luzon: for it is exceedingly fertile, and abounds in rice, swine, fowls, wax, and honey; it produces also a great quantity of cotton
