Ultralimit

In mathematics, an ultralimit is a geometric construction that assigns to a sequence of metric spaces Xn a limiting metric space. The notion of an ultralimit captures the limiting behavior of finite configurations in the spaces Xn and uses an ultrafilter to avoid the process of repeatedly passing to subsequences to ensure convergence. An ultralimit is a generalization of the notion of Gromov–Hausdorff convergence of metric spaces. (Wikipedia).

A Canticle for Leibowitz - Dystopias and Apocalypses - Extra Sci Fi

A Canticle for Leibowitz is a book about cycles and violence--about the cost of progress. But it is also about the persistence of humanity's quest for knowledge and endless resilience. Unlike other post-apocalyptic fiction tropes, it is focused on the lives and goings of everyday people, r

AWESOME SUPERCONDUCTOR LEVITATION!!!

A quantum levitator it's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of fo
