Covariant and contravariant indices are used in tensor calculus to represent different types of vector transformations under coordinate changes. Covariant indices transform with the basis vectors, while contravariant indices transform with the reciprocal basis, ensuring the tensor remains invariant under coordinate transformations.
Social pressure is the influence exerted by society or a social group on individuals to conform to expected norms, behaviors, or attitudes. It can lead to changes in beliefs and actions, often driven by the desire for acceptance, fear of rejection, or perceived authority.
Predominance refers to the state or condition of being greater in number, strength, influence, or importance compared to others.
