A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design.Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits.
A QAPF diagram is a doubled-triangle plot diagram used to classify intrusive igneous rocks based on their mineralogy. The acronym QAPF stands for " Quartz, Alkali feldspar, Plagioclase, Feldspathoid (Foid) ", which are the four mineral groups used for classification in a QAPF diagram. The percentages (ratios) of the Q, A, P and F groups are ...
Brain–body mass ratio, also known as the brain–body weight ratio, is the ratio of brain mass to body mass, which is hypothesized to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases. A more complex measurement, encephalization quotient, takes into account allometric effects of widely divergent ...
Following the Civil War, it was the last state to be restored to the Union, on July 15, 1870.

Gravity data suggests that Ceres has a mean dimensionless moment of inertia (I/MR 2) value of about 0.37 indicating some amount of internal differentiation [5] [23] (a spherical body with a uniform density throughout has a moment of inertia of 0.40 while a body whose mass is mostly concentrated near the center has a moment of inertia closer to ...
Most intersex people identify as either men or women, [ 12] although some identify as only non-binary, some identify as non-binary and genderfluid, such as Hida Viloria, while others identify as non-binary men or non-binary women. Non-binary people as a group vary in their gender expressions, and some may reject gender identity altogether. [ 13]
In power engineering, a single-line diagram ( SLD ), also sometimes called one-line diagram, is a simplest symbolic representation of an electric power system. [ 1][ 2] A single line in the diagram typically corresponds to more than one physical conductor: in a direct current system the line includes the supply and return paths, in a three ...
