Evolution in the interpretation of the Dirac equation I meant "wave equation" to mean "not a field equation". I'll have a look at your references, thanks. |

Why don't spinning tops fall over? At some point you will have to do the math ... |

Material resistency to lasers beam So it's not the duty cycle but the peak power. Duty cycle is "time on" over "total time". |

Mathematica to help for an Hamiltonian problem Thanks, it is not exactly what I was looking for but it might do the trick. About the tags: these two can be made synonyms. |

How neutron stars burn ? Is it decay or fusion or something else? It doesn't burn. |

Why doesn't the bike fall if going with a high speed? @Adrian: you are saying "inertia" because... there is no force... In the case of the rope, the rope is providing a centripetal force. |

Why doesn't the bike fall if going with a high speed? just to be a bit provocative: You are standing upright on your bike, you violently lean on one side, just at the beginning what is the direction of the centrifugal force ? |

Why doesn't the bike fall if going with a high speed? Then you should thought of reading wikipedia in more details. And this: "you get centrifugal force (as oneat correctly pointed out)" is in no way true: imagine yourself in the inertial frame moving with the bike: no speed, so what ? @Davis answer is short but correct. |

Why doesn't the bike fall if going with a high speed? This is a very misleading answer: there is no "centrifugal force", just a centrifugal pseudo-force in a rotating frame. When you look at a bike you generally do not consider a rotating frame, and even if you do, how would you relate the rotational speed of the frame, leading to a centrifugal term to the speed of the bike ? |

Why do we automatically assume that the velocity vector $\vec{v}$ and location vector $\vec{r}$ are independent? And think about real cases as in the first part of my answer. You can then easily deduce if v is independent of x or not. |

Why do we automatically assume that the velocity vector $\vec{v}$ and location vector $\vec{r}$ are independent? Just forget about all these things about the link between v and x. I think there is a big confusion about all this in your question. Start from the basics and try to understand the second part of my answer. |

Simple three-body-problem? Solution to a three-body problem exist when the three bodies are aligned as in your example. |
