When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

Relativistic mass and imaginary mass Why downvote? This is a perfectly valid question. |

Relativistic mass and imaginary mass Never mind. Trust me, there is no logical deduction in physics. Physics is mostly empirical, that is why we have to test everything experimentally. Take QM for example, it is based on equation which you cannot derive -- it is a clever guess. So why not postulate negative and imaginary mass and build some equipment that could detect it? |

Relativistic mass and imaginary mass OK, there is no evidence for the existence of black holes, yet we strongly believe in them. Instead of believing in them we should be skeptical? |

Relativistic mass and imaginary mass By the way, what is wrong with negative mass? To be honest, I have not seen any compelling arguments for excepting only positive mass. We know negative energies are possible, why not negative mass and imaginary mass? |

Relativistic mass and imaginary mass Suppose a particle starts traveling faster than light without getting to the speed of light first. Just because such beasts would cause strange things to happen does not mean it is impossible. |

Relativistic mass and imaginary mass If something has not been observed it does not mean it does not exist. Only a bad physicist can think this way! According to your argument, quantum mechanics is a complete nonsense and we should not believe in it because it makes your head hurt. Overall, a pointless answer. |

Two-dimensional flow @poorsod I don't seem to get anywhere. I think I am making a mistake somewhere. Could you post your partial derivation? |

Two-dimensional flow @poorsod Yes, I tried that, it did not seem to get me anywhere. |

Velocity of two-dimensional flow I guess you're right. |

Velocity of two-dimensional flow Yes, I used the incompressibility, but how do I know it is satisfied? It is not given. |
