Does the observer or the camera collapse the wave function in the double slit experiment? I think your question is what isdefinition of measurement in quantum mechanics or equivalently when does a "wavefunction" collapse happen? For this you can read this article en.wikipedia.org/wiki/Measurement_in_quantum_mechanics Though I don't think there is any universally accepted definition of measurment in QM.See my edited amswer. |

How deep can my knowledge of particle physics go without the maths? To understand paricle physics, you need knowledge of group representation theory and Lie groups. |

How electrons act under rotating magnetic field? The behaviour of an electron is determined by the laws of quantum mechanics not classical mechanics. An electron may not have definite position or momenum. Also. eletrons don't rotate around the nucleus in classical orbits. |

What does the Copenhagen interpretation say about the position of a particle before measurement? A number of physicists have criticized the Afshar's interpretation of his results. They don't believe his experiments voilate the complementarity principle.I guess there is a lot of confusion regarding this. |

What does the Copenhagen interpretation say about the position of a particle before measurement? @annav This is from Quantum Mechanics and Path integrals by Feynman "We shall state the uncertainity principle as follows:Any determination of the alternative taken by a process capable of following more than one alternative destroys the interference between the alternatives". So, if we can determine through which slit electron passed and still retain the interference, we are violating the hiesenberg uncertainity principle according to Feynman. So the hiesenberg uncertainity principle has been experimentally violated? Am I missing something here? |

Are there theories that explain wave-particle duality? @Outlier There is no answer to your question. Your question is like asking why does gravitation varies inversely to the square of the distance. This is fundamental law of nature just like the wave-particle duality. We don't know why nature works the way it is. |
