... they are still interesting for this reason. In particular, each eight-qubit circuit presented here is able to detect periods of two, four, eight, and sixteen, so there are failure modes where an incorrect period could be observed. But these genuine order-finding instances are nongeneric cases from t ...

... symmetric (independent of φ). For example, |Y10 |2 ∝ cos2 θ . So in this state, the particle is more likely to be found near the north pole (θ = 0) or south pole (θ = π), than along the equator θ = π/2. Polar plots of Plm (θ) are given in many text books. ...

Then for quite a while very few deaths will result, for it is unlikely that any one cell should receive ten quanta at the outset. What is happening in the initial period i ...

... Our understanding of matter today is much different than it was long ago. In 440 BC, Aristotle and Plato ( Figure 1.1) proposed that matter was continuous, infinite, present in every form, and always all around us. It was thought that matter could be divided and subdivided into smaller and smaller p ...

When quantum mechanics was being formulated, an ad hoc proposal was introduced to describe the action of a measurement apparatus 1 . This proposal, often called the "collapse postulate," states that a measur ...

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).
