The tensor power trick
Quick description
If one wants to prove an inequality X \leq Y for some non-negative quantities X, Y, but can only see how to prove a quasi-inequality X \leq CY that loses a multiplicative constant C, then try to replace all objects involved in the problem... |

Judy Curry and "BackRadiation"
In the comment Febr 1 12:28 to the thread on Slaying the Sky Dragon on Judy Curry's blog, Judy asks me:
• Do you dispute that if you put an infrared radiometer on the surface of the earth and point it upwards, that it will measure an IR radiance or irradiance (d... |

While investigating the EPR Paradox, it seems like only two options are given, when there could be a third that is not mentioned - Heisenberg's Uncertainty Principle being given up.
The setup is this (in the wikipedia article): given two entangled particles, separated by a large distance, if ... |
1c46c983998c8105 | Does quantum theory have to be interpreted?
by aotell
Witnessing the ongoing discussion about how quantum theory should be interpreted, and the strong opinions and sometimes even dogmatic arguments, I decided to write a series of blog posts that will try to discuss the issue of interpretation as objectively as I poss... |

For a report I'm writing on Quantum Computing, I'm interested in understanding a little about this famous equation. I'm an undergraduate student of math, so I can bear some formalism in the explanation. However I'm not so stupid to think I can understand this landmark without some years of phy... |

Higgs Standard Model
The fundamental types of particles in the Universe, now complete.
5 sigma annoucement
So, the Higgs boson has been discovered! That’s good news. You may have also heard that the Higgs gives mass to everything in the Universe, and that it’s a field.
The odd thing is that all of these things... |

Is time simply the rate of change?
If this is the case and time was created during the big bang would it be the case that the closer you get to the start of the big bang the "slower" things change until you essentially approach a s... |

205d4df01391cb98 | Complex potential model for low-energy neutron scattering
Fiedeldey H. ; Frahn W.E. (1961)
The optical model for low-energy neutron scattering is treated explicitly by means of a new form of complex potential which permits an exact solution of the S-wave Schrödinger equation. This potential is everywhere continuousl... |

I am reading the wikipedia article on the Laplacian matrix:
I don't understand what is the particular use of it; having the diagonals as the degree and why the negative adjacency elements off the diagonal? What use would this have?
Then on reading about its norm, first of all what does a no... |

Quantum mechanics
Quantum mechanics is the study of mechanical systems whose dimensions are close to the atomic scale, such as molecules, atoms, electrons, protons and other subatomic particles. Quantum mechanics is a fundamental branch of physics with wide applications. Quantum theory generalizes cla... |
