Hadouken!
Hadouken! are a British band and was formed in
London in 2006 by singer, writer and producer James Smith, alongside his girlfriend, synth player Alice Spooner, with guitarist Daniel "Pilau" Rice, bassist Christopher Purcell and drummer Nick Rice. The band name is taken from the name of the
special attack of the same name from the
Street Fighter video game series. It was in Leeds that Hadouken! began their own
record label, Surface Noise Records.
Hamiltonian mechanics
Hamiltonian mechanics is a
theory developed as a reformulation of
classical mechanics and predicts the same outcomes as non-Hamiltonian classical mechanics. It uses a different mathematical formalism, providing a more abstract understanding of the theory. Historically, it was an important reformulation of classical mechanics, which later contributed to the formulation of
statistical mechanics and
quantum mechanics.
Hydride
In chemistry, a
hydride is the
anion of
hydrogen, H
-, or, more commonly, it is a
compound in which one or more hydrogen centres have nucleophilic, reducing, or basic properties. In compounds that are regarded as hydrides, the hydrogen atom is bonded to a more
electropositive element or group. Compounds containing hydrogen bonded to metals or metalloid may also be referred to as hydrides, even though in this case the hydrogen atoms can have a
protic character. Almost all of the elements form
binary compounds with hydrogen, the exceptions being
He,
Ne,
Ar,
Kr,
Pm,
Os,
Ir,
Rn,
Fr, and
Ra.
Include directive
Many
programming languages and other computer files have a
directive, often called
include (as well as
copy and
import), that causes the contents of a second file to be inserted into the original file. These included files are called copybooks or header files. They are often used to define the physical layout of program data, pieces of procedural code and/or
forward declarations while promoting
encapsulation and the reuse of code.
