Quantum Information and Quantum Computation
... Over the last half century, the components of computers have gotten smaller by a factor of two every year and a half, the phenomenon known as Moore's law. In current computers, the smallest wires and transistors are coming close to a size of one hundred nanometers across, a thousand times the diamet ...

... no importance to us until we come to stars. They merely add to the mass of the nucleus, for they are electrically neutral. For each given z several possible neutron numbers actually occur in nature; these different nuclei with a common z are called isotopes of each other. For example, when z = 1 we ...

... The arrow marks the smallest action for a closed orbit for this system, Ŝ56.89. The inset shows the region R<0.2 and Ŝ<4 by expanding both the x and y axes by a factor of 2.5. In both Figs. 2 and 3 there are peaks at actions much shorter than is possible in closed-orbit theory. In particular, the ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
