... my attention was in the “Mathematical Recreations” column, which, at that time, was written by the mathematician Ian Stewart. The article dealt with Fermat’s last theorem. Even if I did not understand a single line on Diophantine equations and I was mostly interested in the intriguing illustration c ...

... cannot be created by these operations. As it turns out, the standard definition of multipartite nonlocality, adopted by the community so far, is inconsistent with our operational characterisation. Therefore, we introduce a new class of models that overcome these inconsistencies. By using a special cl ...

Also note that the probability for a given outcome depends only on the (cosine of the) angle between the two detectors and ...

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).
