6266 | We need the correspondence theory of truth to understand language and science [Putnam] |

6264 | In Tarski's definition, you understand 'true' if you accept the notions of the object language [Putnam] |

6269 | Only Tarski has found a way to define 'true' [Putnam] |
6280 | Realism is a theory, which explains the convergence of science and the success of language [Putnam] |
6284 | If a tautology is immune from revision, why would that make it true? [Putnam] |
6273 | Knowledge depends on believing others, which must be innate, as inferences are not strong enough [Putnam] |

6283 | Language maps the world in many ways (because it maps onto other languages in many ways) [Putnam] |

21167 | Gravity is unusual, in that it always attracts and never repels [New Sci.] |

21143 | Quarks in threes can build hadrons with spin ½ or with spin 3/2 [New Sci.] |
21150 | Three different colours of quark (as in the proton) can cancel out to give no colour [New Sci.] |
21145 | The four fundamental forces (gravity, electromagnetism, weak and strong) are the effects of particles [New Sci.] |
21153 | The weak force explains beta decay, and the change of type by quarks and leptons [New Sci.] |
21154 | Three particles enable the weak force: W+ and W- are charged, and Z° is not [New Sci.] |
21156 | The weak force particles are heavy, so the force has a short range [New Sci.] |
21164 | Why do the charges of the very different proton and electron perfectly match up? [New Sci.] |

21165 | Spin is akin to rotation, and is easily measured in a magnetic field [New Sci.] |

21168 | Gravitional mass turns out to be the same as inertial mass [New Sci.] |
