Is one way glass possible? Can we buy this anywhere? Or is the only way to build one ourselves? |

Is one way glass possible? Do they sell these things? Can we buy an optical isolator or do we have to build one ourself? |

Learning physics online? @mtrencseni, is it best (build on previous knowledge) to consume them in the order you listed? |

Learning physics online? @Matt, so let's just say someone has zero experience in physics, what path of learning may be the best way to cover all the cores? |

How does Bell's theorem rule out the possibility of local hidden variables? @JohnRennie, are you saying that Bell's theorem does not rule out the possibility of local hidden variables? |

Are a quantum mechanical system a chaotic (yet deterministic) system? @kleingordon, how does Bell's inequalities ruled out the possibility of local hidden variables? |

If the universe started again with exactly the same conditions… would it be the same? Please elaborate... |

Randomness, Chaos, Quantum mechanical probability functions Do you mind explaining why "quantum particles behave randomly on their own because that is just what they do"? Since we do not currently know everything about the physical world, Why couldn't it be such that quantum particles are totally deterministic provided if we have the 100% precise model of the world? |

If randomness doesn't exist, how come the universe isn't a perfect sphere with predictable distribution of matter? @David, Why do almost all serious scientists these days accept nondeterminism? Is there a simple explanation to this? |

Dumbed-down explanation how scientists know the number of atoms in the universe? I don't know whether the numbers are more likely for or more likely for not, hence the question in the very first place. I've edited the question to reflect this issue. |

Dumbed-down explanation how scientists know the number of atoms in the universe? And if there's logically less than 50% chance that these numbers are right, isn't it more reasonable to say "the number of atoms in the universe is unknown" than to say "the number of atoms in the universe is ~$10^{70}$"? |

Dumbed-down explanation how scientists know the number of atoms in the universe? But how is it possible that "each containing on average close to a trillion stars" could be verified reasonably enough, for us to say with enough certainty and conviction that there's over 50% chance that it is correct? For all we know, out of this 100 billion galaxy there could be a single galaxy that already has over $10^{23}$ stars... just curious. |

Is GPS time measuring the proper time on the mean sea level or the GPS station itself? Hmm then perhaps off topic, but are you aware why are there both GPS time and TAI time if they are in fact the same thing? |
