Why Won't a Tight Cable Ever Be Fully Straight? Doesn't this argument imply that no objects can be perfectly straight? |

Is the universe fundamentally deterministic? @Walkerneo: According to the Copenhagen interpretation of QM, it does mean the universe is non-deterministic. There are other interpretations of QM which allow for determinism though. Which is the correct interpretation (if any)? Currently, no one knows. |

Help me get out of a speeding ticket I remember reading about this. The professor wrote this paper to get out of an actual speeding ticket, and presented it in court. It worked; he avoided the ticket. Afterwards, he admitted there was an error with his reasoning, and asked if anyone could figure out what it was. [ Edit ]: Linky linky |

What are the differences between indistinguishable and identical? @josh and twistor: Probably a less ambiguous word for this than 'distinguishable' would be 'distinct'. |

Why do tuning forks have two prongs? FYI someone asked essentially the same question in response to this one, and got a very nice answer: physics.stackexchange.com/questions/51847 |

Why don't tuning forks have three prongs? This probably should have been the accepted answer to the other question as well - this clears up all the confusion for me. Thanks! |

Why do tuning forks have two prongs? "a fork with two prongs oscillates in such a way that the point of contact with your hand does not move much due to the oscillation of the fork" - Er, why? If we removed one of the prongs, would that still be true? What if we added a third prong? Do we have any equations to explain this? |

Why do tuning forks have two prongs? "after all, orchestras usually tune to instruments, not tuning forks." - They tune to instruments because some instruments (particularly, oboes) cannot be easily tuned, so everyone else has to tune with respect to them. It has nothing to do with whether or not tuning forks are good enough. |

Why is the sky not purple? So does this mean that if we were to analyze the spectrum of light from the sky, we'd actually see nearly the same amount of violet and blue; but for whatever reason our eyes don't detect it that way? Somehow that seems dubious to me. |

Does juggling balls reduce the total weight of the juggler and balls? Strange, I just read this in a book called something like "Fantastic Science Puzzles" (I don't have it on me), and was going to ask this very question tomorrow, as I am almost certain it is wrong. |

Is time continuous? -1, by this logic, the theory that matter or energy come in discrete packets is untestable as well |

Can a photon be emitted with a wavelength > 299,792,458 meters, and would this violate c? That's the number of meters light travels in one second. The length of "one second" was arbitrarily decided by humans, so passing that arbitrary boundary (causing the frequency to be <1Hz) shouldn't be anything special. |
