Does the slinky base stay perfectly level during the initial free fall @007: Thanks for the reference. Interesting to see some calculation, that I could not have done quickly myself. They are calculating an estimate for the characteristic time, not the forces involved. |

Does the slinky base stay perfectly level during the initial free fall No. The answer just states the obviously: 1. Center of mass is in free fall. 2. There is tension pulling up. I am asking if the balance is perfect. |

How wide does a wall of ice need to be to stay in place? ρhg ~ 1000kg/m^3 * 200m * 10m/s^2 = 2000000kg/m/s^2 = 2MPa. So I think that it is safe to assume, that all of the ice will be in phase I. -but what is the minimum width of a 200 m wall? |

Why are the inner products of the eigenfunctions of an operator with a discrete eigenvalue spectrum guaranteed to exist? I think that this question is (also) suitable for a math forum. -you might get better answers. |

Are there devices which convert thermal energy to electric energy? @Tarek: So you seek something that you already know doesn't exist!? |

Why isn't the symmetric twin paradox a paradox? Good explanation +1. But you do need general relativity, to explain what happens in the acceleration phase. That is also why you elegantly skip that part. General relativity is also needed to explain the non-symetry of the normal twin paradox(one stays in the same inertial frame, and the other goes trough an acceleration at one point). |

Pressure of sealed in liquid nitrogen 82 atm is not a very high lower limit.- but I will accept, that the answer is not simple. |

Reference for phase diagrams of elements @dmckee: See my comment to Alexander. I will accept your Wolfram link as answer to this question. - have posted a new one: physics.stackexchange.com/questions/29523/… |

Reference for phase diagrams of elements @Alexander: One thing that the phase diagram shows is that the ideal gas law can not be used to make the estimate. The answer is not 694 atm. physics.stackexchange.com/questions/29523/… |

Pressure of sealed in liquid nitrogen @Pygmalion: A very dangerous experiment, if you do not have a rough estimate :o) |
