The Einstein field equations (EFE) may be written in the form: [5] [1] + = EFE on a wall in Leiden, Netherlands. where is the Einstein tensor, is the metric tensor, is the stress–energy tensor, is the cosmological constant and is the Einstein gravitational constant.
Anna Pauline "Pauli" Murray (November 20, 1910 – July 1, 1985) was an American civil rights activist, advocate, legal scholar and theorist, author and – later in life – an Episcopal priest.
The wing and rear horizontal control surfaces of the base F-16A were replaced with a cranked-arrow delta wing 115% larger than the original wing. [15] Extensive use of graphite-bismaleimide composites allowed the savings of 595 pounds (270 kg) of weight, [ 16 ] but the F-16XL-1 and XL-2 were 4,100 pounds (1,900 kg) and 5,600 pounds (2,500 kg ...

The Yukon–Kuskokwim Delta is a river delta located where the Yukon and Kuskokwim rivers empty into the Bering Sea on the west coast of the U.S. state of Alaska. At approximately 129,500 square kilometers (50,000 sq mi) in size, [ 1 ] it is one of the largest deltas in the world.
In mathematical analysis, the Dirac delta function (or δ distribution), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one.
Vashti was born on May 28, 1947, in Baltimore, Maryland. She is the daughter of Samuel Edward Smith and Ida Murphy Smith Peters. [6] She was named after her maternal grandmother, Vashti Turley Murphy, [7] who was one of 22 women who founded the Delta Sigma Theta sorority in 1913, while a student at Howard University.
Thus, with the sign convention for a heat transferred in a thermodynamic process (> for an absorption and < for a dissipation) we get: = | | + | | = = Since this equality holds over an entire Carnot cycle, it gave Clausius the hint that at each stage of the cycle the difference between a work and a net heat would be conserved, rather than a net ...
