Dot product in coordinates Ah sorry, I skipped over the part "At first you can prove that dot product is linear..." and thought it just assumed it. |

Dot product in coordinates How does this show that $v \cdot w = |v| |w| \cos \theta$? |

Motivating Example for Algebraic Geometry/Scheme Theory Thanks for the links, Akhil and Kevin. They are very helpful. The fact that Spec is adjoint to the global sections functor seems like a really good reason for Spec over MSpec. @Akhil: I'm going to have to get further in my study of schemes before I attempt to digest your last paragraph. |

Why are Hopf algebras called quantum groups? @BBischof: thanks for the link. I'm really interested in this stuff and have seen Rosenberg's name pop-up quite a few times. |

What is the difference between matrix theory and linear algebra? This question received satisfying answers on mathoverflow and I see no reason for it to be here. |

Why are Hopf algebras called quantum groups? @BBischof I am also interested in this same issue and I do not know much more than what I said in my answer. When I said quantum space I really meant (rather circularly) a "space" whose algebra of functions is non-commutative. |

What's the difference between open and closed sets? I think this is too vague of a question and is not a very good seeded question. If the questioner knows what a topology is, then they would be able to make the question more precise. If they don't know what a topology is, then they shouldn't be asking this question. |

Why is the integral expression for the length of a curve more complicated than the expression for area or volume of a figure rotated? In all cases you're integrating a differential form. The cases are really not different since in each one you integrate the volume element over a manifold (a 1-manifold in the case of finding the length of the curve). The difference is that in finding the length of the curve, the volume element is induced by the metric. |
