A Krasnikov tube is a speculative mechanism for space travel involving the warping of spacetime into permanent superluminal tunnels. The resulting structure is analogous to a wormhole or an immobile Alcubierre drive (and like them requires exotic matter with negative energy density) with the endpoints displaced in time as well as space. The idea was proposed by Sergey Krasnikov in 1995. (Wikipedia).

Russian KL-1 Circular "Slide Rule" (1/2 -- basics)
The Russian KL-1 Circular "Slide Rule" is not really a slide rule at all! In this video I explain the difference but also, how to use it. I assume some familiarity with slide rules, so if you're lost, watch the first video from my playlist below. This is the first video of two on the KL-1.

Abstract: T-structures on derived categories of coherent sheaves are an important tool to encode both representation-theoretic and geometric information. Unfortunately there are only a limited amount of tools available for the constructions of such t-structures. We show how certain geometr
