3b3db00d205fac9d | "Does the moon exist when no one is looking at it?"
—Albert Einstein, asked of Niels Bohr
Suppose you were just starting to work out a theory of quantum mechanics.
You begin to encounter experiments that deliver different results depending on how closely you observe them. You dig underneath the reality you know, and ... |

FOR THE FUTURE OF LENR by Abd ul-Rahman Lomax
Peter has asked me to write a “guest editorial in which you tell what YOU suggest as he best ideas and most recommended modes of thinking- for the future you wish to LENR.”
I'm tempted to dismantle this, so I'll get that out of the way first:

0a704a5bddee1e8f | Imagine that we find very special 3D cameras on sale. We get a few hundred of them and give them to several groups of students for a weekend project. Each student gets a camera and just one hydrogen atom in a special box. Their task is to take as many photographs of their hydrogen atom as possible. Well, you know that ... |

For something I'm writing -- I'm interested in examples of bad arguments which involve the application of mathematical theorems in non-mathematical contexts. E.G. folks who make theological arguments based on (what they take to be) Godel's theorem, or Bayesian arguments for creationism. (If necessary I'm wil... |

Nonlinear subelliptic Schrodinger equations with external magnetic field
Kyril Tintarev
To account for an external magnetic field in a Hamiltonian of a quantum system on a manifold (modelled here by a subelliptic Dirichlet form), one replaces the the momen... |

Why is the wave function complex? I've collected some layman explanations but they are incomplete and unsatisfactory. However in the book by Merzbacher in the initial few pages he provides an explanation that I need some help with: that the de Broglie wavelength and the wavelength of an elastic wave do not ... |

9d3a7f1d43c0469c | Contrary to Popular Belief, Einstein Was Not Mistaken About Quantum Mechanics
Misconceptions and assumptions concerning quantum mechanics
I get somewhat frustrated every time I read another blog post, book review, or journal article that claims Einstein was wrong about quantum mechanics (QM). It must make for good h... |

ef8cf2c3af23d4c5 | Matrix mechanics
Matrix mechanics is a formulation of quantum mechanics created by Werner Heisenberg, Max Born, and Pascual Jordan in 1925.
Matrix mechanics was the first complete and correct definition of quantum mechanics. It extended the Bohr Model by describing how the quantum jumps occur. It did so by interpreti... |

In particle physics, the Higgs mechanism is essential to explain the generation mechanism of the property "mass". This is a most-important property of almost all elementary particles.[1]
According to this theory, particles gain mass by interacting with the so-called Higgs field that permeates a... |
