d3159337ceb80df5 | Why does plutonium have more oxidation states than samarium?
Electron configuration of Pu: $\ce{[Rn] 5f^6 7s^2}$
Electron configuration of Sm: $\ce{[Xe] 4f^6 6s^2}$
I thought that only the valence electrons affected the oxidation states, so why does plutonium have more oxidation states (6,5,4,3) than samarium (2,3) ... |

Non-Relativistic QCD
This is another installment in our series about fermions on the lattice. In the previous posts in this series we had looked at various lattice discretisations of the continuum Dirac action, and how they dealt with the problem of doublers posed by the Nielsen-Ninomiya theorem.... |

Network Theory (Part 15)
John Baez
Today I'll show you how a molecule can carry out a random walk on this graph. Then I'll get to work showing how any graph gives:
The trick is to use an operator called the 'graph Laplacian', a discretized version of the Laplacian which happens to be both infinite... |

The Physics of Evolution
From the viewpoint of a physicist, evolution can be seen as a search for stability. Consider a system of atoms in the framework of non-relativistic quantum mechanics and statistics. Its configuration is a set of values of all generalized coordinates of the system, e.... |

1. The exciton is defined as a bound state of an electron and an electron hole. From what I've read, this state is described by Coulomb's law. Coulomb's law describes the interaction between two charged particles. So my question is: because an electron hole is ... |

One of the fundamental aspects of physics is the study of light and how that interacts with matter. I have been putting off this post – mainly because I am not a quantum mechanic (I am a classical mechanic). There are lots of things that could be done in this post, but I am going to try and keep it limited... |
