The Saga of the Sunstones
In the Dark Ages, the Vikings set out in their longships to slaughter, rape, pillage, and conduct sophisticated measurements in optical physics. That, at least, has been the version of horrible history presented recently by some experimental physicists, who have demo... |

I was wondering about the following:
If you have the time-dependent Schrödinger equation such that $$i \hbar \frac{\partial\psi(x,t)}{\partial t} = - \frac{\hbar^2}{2m} \frac{\partial^2\psi(x,t)}{\partial x^2} + V(x,t) \psi(x,t),$$
where the potential is also time dependent. What is the gene... |

Does the Hamiltonian always translate to the energy of a system? What about in QM? So by the Schrodinger equation, is it true then that $i\hbar{\partial\over\partial t}|\psi\rangle=H|\psi\rangle$ means that $i\hbar{\partial\over\partial t}$ is also an energy operator? How can we interpret this... |

Professional skills and experience are hard won from education, training and time in the industry. But it's amazing how many people get by despite a fundamental lack of knowledge.

cd3ae9e44f6083a1 | Is it possible to calculate the energy of electron in any orbital and atom in the Schrödinger wave model theory? If so, how? E.g. energy of the $3s^2$ electron of the $\ce{Na-}$ ion.
It is surely possible. Note though, that for many-electron systems orbital picture is an approximate description, but that is an approx... |

Tegmark on book tour
I criticized Max Tegmark's new book, and I attended his book tour lecture in Santa Cruz.
He mainly tried to impress the audience that the history of science had two big trends: finding the universe to be bigger than expected, and finding it to be more mathematical than... |

dcc468bc9263d756 | In our course on physical chemistry, which involves MOT, we have been taught that in the LCAO approach, the wave function for a molecule … say hydrogen ion ($\ce{H2+}$), can be approximated by a linear combination of two atomic orbitals.
From what I could gather from the very little I know about variational method is ... |
