I'm a graphics programmer, an amateur physicist, and a sci-fi nerd. I teach computers how to make pretty pictures. I'm excited by beautiful, immersive, story-driven games and interactive fiction. I enjoy messing around with esoteric ideas. I like explaining things.

Least square solution based on the pseudoinverse solved efficiently with singular value decomposition You can start by reading the Wikipedia article on SVD. Calculating the Moore-Penrose pseudoinverse is the first thing listed in the applications section. |

$E=A\cup B$ measurable $\Rightarrow$ $A,\ B$ are measurable. What's the actual question? |

Reflection around a plane, parallel to a line That sounds like it would work to me. |

What's the difference between hyperreal and surreal numbers? Interesting. Could you elaborate on the embedding? I'm just trying to get some intuition for this, not formal details. Are there "typical" or "natural" embeddings, and given such an embedding, where would the extra surreals be? For instance, is it somewhat analogous to how the rationals are embedded in the reals, where the rationals are dense but there are extra real numbers "between" the rationals? |

Can this function be rewritten to improve numerical stability? Very interesting! That is some deep magic right there. |
