2001 Image of the active delta front before Hurricanes Katrina and Rita destroyed much of the delta in 2005. The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre (4,700 sq mi; 12,000 km 2) area of land that stretches from ...
Δ−. (ddd), which respectively carry an electric charge of +2 e, +1 e, 0 e, and −1 e . The Δ baryons have a mass of about 1 232 MeV/c2; their third component of isospin and they are required to have an intrinsic spin of 3 2 or higher (half-integer units). Ordinary nucleons (symbol N, meaning either a proton or neutron ), by contrast, have ...
Delta operates the world's largest fleets of the Airbus A220, Boeing 717, and Boeing 757, the largest passenger fleet of the Boeing 767, and the largest Airbus A330 fleet of any US airline. Delta has historically preferred purchasing or leasing used aircraft or using older-generation models to keep initial acquisition costs down.
Kronecker delta. In mathematics, the Kronecker delta (named after Leopold Kronecker) is a function of two variables, usually just non-negative integers. The function is 1 if the variables are equal, and 0 otherwise: or with use of Iverson brackets : For example, because , whereas because . The Kronecker delta appears naturally in many areas of ...

The Nile Delta ( Arabic: دلتا النيل, Delta an-Nīl or simply الدلتا, ad-Delta) is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. [1] It is one of the world's larger deltas—from Alexandria in the west to Port ...
The Delta rocket family was a versatile range of American rocket -powered expendable launch systems that provided space launch capability in the United States from 1960 to 2024. Japan also launched license-built derivatives ( N-I, N-II, and H-I) from 1975 to 1992. More than 300 Delta rockets were launched with a 95% success rate.
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 Delta Delta. Delta Delta Delta ( ΔΔΔ ), also known as Tri Delta, is a global [2] women's fraternity and Greek life organization founded on November 27, 1888 at Boston University by Sarah Ida Shaw, Eleanor Dorcas Pond, Isabel Morgan Breed, and Florence Isabelle Stewart. With over 200,000 living initiates at 141 chapters and over $450M ...
