In his book "Einstein's mistakes" H. C. Ohanian, the author, holds that Einstein delivered 7 proofs for $E=mc^2$ in his life that all were in some way incorrect. This despite the fact that correct proves had been published and mistakes in his proofs were sometimes pointed out to him.

In physics, a wave packet is an envelope or packet containing an arbitrary number of wave forms. In quantum mechanics the wave packet is ascribed a special significance: it is interpreted to be a "proba... |
3808d65b508942ed | La face quantique de la gravité
La physique théorique est à la croisée des chemins, et nul ne sait pour l’instant ce qui se trouve au-delà de la relativité générale ou du Modèle standard. Il est admis que nous ne pourrons progresser qu’avec une théorie plus complète de la gravité quantique, qui unifierait peut-être la... |

Last updated
Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays . The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances.

What is an oscillator?
A classical oscillator is an object of mass mm attached to a spring of force constant kk. The spring exerts a restoring force F=kxF=-kx on the object, where xx is the displacement from the equilibrium position.

The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic potential (V, A), despite being confined to a region in which both the magnetic fie... |
d0b02cf6519a36d8 | As a boy, I was a rock hound, and I learned how to identify minerals with the Mohs hardness test, named after the mineralogist who invented it. You take a known specimen, like quartz, and scratch an unknown specimen with it. If the quartz scratches the mystery specimen, you know it’s softer than quartz. It could be cal... |

Questions related to the quantum aspects of twistorialization
The progress in the understanding of the classical aspects of twistor lift of TGD makes possible to consider in detail the quantum aspects of twistorialization of TGD and for the first time an explicit proposal for the part of ... |

In classical mechanics you construct an action (involving a Lagrangian in arbitrary generalized coordinates, a Hamiltonian in canonical coordinates [to make your EOM more "convenient & symmetric"]), then extremizing it gives the equations of motion. Alternatively one can find a first order PDE for the action... |

Quantum mechanics is generally regarded as the physical theory that is our best candidate for a fundamental and universal description of the physical world. The conceptual framework employed by this theory differs drastica... |

Supppose we are given a quantum state that isn't pure state, such that it is a linear combination of the eigenstates of a Hermitian operator $\hat O$. $$|\psi\rangle=N\sum \alpha_i |i\rangle$$ where $N$ is just a normalization constant. I just want to make something clear about measuring. If w... |
