In the Standard Model of particle physics, the Higgs mechanism is essential to explain the generation mechanism of the property "mass" for gauge bosons. Without the Higgs mechanism, all bosons (a type of fundamental particle) would be c... |

The Past and Imagined Future
We look up into the stars and darkness of the night sky and see only the past, which are the sounds and images of many possible futures. In fact, all of what we ever hear or see is a memory of our past and in the sky we see a sun as it was eight minutes ago, a "nea... |

The scale of atoms
Saw this on Phil Plait's Bad Astronomy blog and loved it. Phycisist Brian Cox on a BBC show called "A Night With the Stars" talking about why atoms are mostly empty space. Watch it!
As Plait says "Post script: can you imagine a show like this running on American TV? N... |

the computation is the message
A computational version of quantum mechanics in the spirit of the Hartree method is presented in which each electron in a multi-electron system updates its own state over time by solving its own Schrödinger equation in three-dimensional space expressing th... |

I have heard that one can recover classical mechanics from quantum mechanics in the limit the $\hbar$ goes to zero. How can this be done? (Ideally, I would love to see something like: as $\hbar$ goes to zero, the position wavefuncti... |

When solving Schrödinger's equation for a 3D quantum well with infinite barriers, my reference states that: $$\psi(x,y,z) = \psi(x)\psi(y)\psi(z) \quad\text{when}\quad V(x,y,z) = V(x) + V(y) + V(z) = V(z).$$ However, I cannot find any rationale for this statement. It may be obvious, but I would appreciate an... |
