How can I vizualize and understand curved spaces in general relativity? By the way psychology research suggests that the humans' vision perception of the world (3 Dimensional vision) completely depends on external stimuli we were all exposed to during youth. So perhaps with appropriate training we humans just might be able to visualize 4D space! |

How much energy Maxwell's demon will earn? What do you mean by how much energy does the daemon gain? Do you mean the work that can be extracted? Any increase in internal energy? |

A thought experiment with Heisenberg's Uncertainty Principle It should be an inequality... Anyways it means a measure of the standard deviation of momentum. The other one is the standard deviation of position. In quantum mechanics the idea is that say the state of the system is $\psi$. We have a momentum operator $P$ such that if a particle 'has momentum' $p$ then the relation $P\psi = p\psi$ hols. The states for which this holds, as mentioned, are unphysical. The computer could give you many things, depending on what the Box detects, the implementation... But they are all unphysical. |

A thought experiment with Heisenberg's Uncertainty Principle Don't be too harsh on Ehryk... I think he just doesn't understand the matter which he's dabbling on too much so he posted an apparently contradictory answer. Come'on, it isn't THAT bad. Just explain the concepts to him! |

The meaning of imaginary time I sometimes think imaginary time should be space and complex time should mean a combination of space and time twisted together... Thanks to relativity. I speculate this since in the metrics of relativity, the signs of space and time components are opposite, so taking their square roots would... |

Is it possible that the Big Bang was caused by virtual particle creation? @fireeyedboy QFT describes the phase space, not spacetime. Thus, I do not think QFT can actually somehow 'create' spacetimes. |

Is it possible that the Big Bang was caused by virtual particle creation? @fireeyedboy If a theory describes something independent with spacetime, would you consider it unphysical? That's what I mean. |

Is it possible that the Big Bang was caused by virtual particle creation? @fireeyedboy Well, quantum states are in the Hilbert space, not spacetime. But to predict something not in spacetime, I would consider highly unphysical. |

To which extent is general relativity a gauge theory? @jdm A quick search on google reveals what you speak of as the spin connection. (puny)I can't relate it to this question(yet?) though. |

Help with Chaos theory! I need an investigation topic @Nemo I understnad. But if you do the EE that way I'm going to be even more uncertain of your grades. |
