The purpose of a physicist is to organize human experience which is composed of description into a logically coherent picture.

Why is it that the atom is considered invariant? What we measure is experimental quantities, and we observe that our instruments have not recorded a change in the properties of the atom therefore we consider the atom to have invariant properties. You can ask. Do the properties of the atom remain same as the universe evolves? and that is a completely meaningful question to ask and some people study such theories, and even attempt to observe change in properties by looking at light from really ancient sources. |

Are the Maxwell equations a correct description of the wave character of photons? @BenCrowell I have 2 Questions, First how is the probability defined , if you use maxwells equation as wave equation for a photon(My guess is it will be E^2+B^2). Second what does fermionic nature have to being unable to use classical apparatus to detect the field like nature of the Electron. |

Is there any relation between weak and strong fields, similar to electric and magnetic fields? I dont understand your question, Perhaps you are referring to the standard model. |

“S-duality” between confinement and the Higgs mechanism? It will be nice if he does, Perhaps I should work towards the paper posted in the comments instead. |

Why do whips hurt so much? @tony I dont quite understand the intention behind comment 2, perhaps you should clarify. Momentum conservation is the reason. one end of the whip is held constant, and the other is set in motion. so end result is the static end gets larger and larger while the moving end gets smaller and smaller. |

Why do whips hurt so much? @tony there will be effects due to fluid mechanics which will be hard to analyze, and but effects like air drag, viscosity will be important. then there will be effects due to tension and so on, which will cause the tip to slow down and not allow it to reach infinity. In the extreme and unlikely cases the whip could snap into 2.(which can happen with noodles for instance, its only a matter of scales) |

Why do we feel the passing of time? Clocks measure proper time along the motion of the observer. and you compare clocks of moving and stationary observers and observer dilation. |

Energy time complementarity from unitary evolution I think there is a well defined meaning for energy atleast at large times. When the atom and the photon are sufficiently far apart we can say that interaction between the atom and photon is zero, the total energy of the atom +photon is a well defined quantity. However as you said we will observe distributions. The final energy is a well defined measurable object, however the initial energy(of state in an atomic superposition) is not, however if we look at how the state was prepared then i think it is meaningful to study energy conservation. |
