Time in Girard's Geometry of Interaction
@Trent, I think the style is intentional and goes back to Georg Kreisel and even Ludwig Wittgenstein. |

How short can we state the Axiom of Choice?
Quantifier complexity might be more relevant to your intended simplicity than total length. |

How do we recognize an integer inside the rationals?
@LSpice, I didn't mean just once but until they become integers. |

Busy Beaver modulo 2
It is similar here: the answer depends on the details of Turing machine model and typically computability theorists are interested in studying computability, they are not much interested in studying the details of particular Turing models and non-robust notions dependent on such details. |

Busy Beaver modulo 2
@Matt, let me give a better analogy to explain the difference between the question about computability of BB mod 2 and the question about computability of BB from linear algebra: "is $e_1$ one of the basis vectors of a given subspace $S$ of $\Re^n$ (without specifying any particular basis for $S$)?" does not make sense. On the other hand, the number of basis vectors of $S$ makes sense even if we don't specify a basis for $S$. We can of course make the first question sensible by fixing a basis but then the question is not about the subspace but the particular basis. |

Thanks @Andres, the preface and the first chapters of the book look promising. |
