Why is the meander ratio of a river $= \pi$? This may be interesting reading: en.wikipedia.org/wiki/Buffon's_needle |

Defining collision point in 3D Your problem does not have an unique solution with this information. Aiming at the path of object A, you can hit it anywhere on that path with the right velocity |

Is it possible that 5 planets can revolve around a single star in a single orbit? @dmckee Only he wants a central star :) |

Mechanics question I am a bit confused with the orientation of the ride. Do I understand correctly that the axis of the cylinder (and thus the rotation axis), is initially aligned with the direction of gravity? And then after some time, this axis is rotated over 90 degrees, to go from vertical to horizontal wrt ground level? |

Product of VEVs vs. VEV of product But if the field is constant, then, isn't this statement obvious? |

Physics behind the flow of gas coming out of a balloon This sounds plausible to me. I think your odd of calculating pb are small. As $p_b$ would be only dependent on the pressure difference, you might be able to perform some experiments on ground level, by varying $p_i$. |

How can I find the frequency? Did you calculate the spring constant? |

Explanation for the next steps of chaplygin dipole Indeed, for now it looks mostly like a math problem. I think the differential equation itself is solved 'easily'. |

Workdone in an equipotential surface is zero? Can you maybe add some interpunction, capitals etc? |

What's the motion of this yoyo under external force will be? It's not my question, but I think the question is a bit lame when only pulling horizontally. |

What's the motion of this yoyo under external force will be? How did you include the angle with which the string is pulled? Try with a real yoyo, you can upwind or unwind it, depending on the angle of the string with the horizontal. This is something that you should include in the derivation. |

Navier-Stokes system This is all explained in the Wikipedia article about the Navier-Stokes equations. Can you indicate what it is, that is not clear about this? |
