Quantum Mechanics, Potentiality, Ontology, Epistemology, & Probability
What is and what is known about what is are two concepts which are often entangled, especially in quantum mechanics (puns intentional). This is one of the subjects which I cover in my upcoming book, i... |

Impressions from the Loops '07
The Loops 2007 this year was held at the University in Morelia, Mexico, in a very nice building (see also Stefan's previous post). The auditorium had a stage with the speaker being in the spotlight, the seats were very comfortable to doze off, and the hallways ha... |

Showing that the Schrödinger equation implies the de Broglie relation when PE=0
1. Nov 1, 2012 #1
In the book physical chemistry (P. Atkins & Julio de Paula, 2009, 5 ED) the authors derive a justification of the Schrödinger equation.

The theoretical chemist is accustomed to judging the success of a theoretical prediction according to how well it agrees with an experimental measurement. Since the object of theory is the prediction of the results of experiment, that would appear to be an entire... |

Mathematical model
(Redirected from Mathematical modeling)
A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences (such as physics... |

Does Quantum Physics Make it Easier to Believe in God?
Quantum mechanics, however, throws a monkey wrench into this simple mechanical view of things. No less a figure than Eugene Wigner, a Nobel Prize winner in physics, claimed that materialism — at least with regard to... |
