Delta-v (more known as " change in velocity "), symbolized as and pronounced deltah-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver. It is a scalar that has the units of ...

Delta method. In statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian .
The Dassault Mirage 2000 is among the most successful delta-winged fighter jets, being used by many countries to this day. A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ). Although long studied, it did not find significant applications until the Jet Age ...
Single delta potential. The time-independent Schrödinger equation for the wave function ψ(x) of a particle in one dimension in a potential V(x) is. where ħ is the reduced Planck constant, and E is the energy of the particle. The delta potential is the potential. where δ(x) is the Dirac delta function. It is called a delta potential well if ...
The Mississippi Delta, also known as the Yazoo–Mississippi Delta, or simply the Delta, is the distinctive northwest section of the U.S. state of Mississippi (and portions of Arkansas and Louisiana) that lies between the Mississippi and Yazoo rivers. The region has been called "The Most Southern Place on Earth" [1] ("Southern" in the sense of ...
