grads

Grads is a term with multiple meanings, depending on context. In mathematics and related fields, it refers to the gradient operator. In education and everyday use, it often means graduates—people who have completed a degree or are associated with graduate-level studies.

In mathematics, grad, short for gradient, denotes a vector-valued operator that applies to a scalar field. For a differentiable function f: R^n → R, the gradient is written as grad f or ∇f and equals the vector of its partial derivatives: (∂f/∂x1, ..., ∂f/∂xn). The gradient points in the direction of the steepest ascent of f, and its magnitude gives the rate of that fastest increase. It is perpendicular to the level sets h = f(x) = c. The gradient interacts with other concepts such as directional derivatives and optimization, where gradient descent uses the negative gradient to minimize a function. In physics and geometry, gradients are used to describe fields that derive from a potential, with ∇f representing the local rate of change of the potential.

As a social and educational term, grads commonly means graduates. A graduate is someone who has completed a degree or program, such as a bachelor’s, master’s, or doctoral degree. The phrase “grad school” refers to graduate education beyond the bachelor’s level. Colloquially, “grads” can describe alumni or recent graduates, and is often used in announcements, class notes, or campus communications. The term is especially prevalent in North American English.
