Amer. Math. Soc.. The main purpose of this paper is to formalise the “supercriticality barrier” for the global regularity problem for the Navier-Stokes equation, which roughly speaking asserts that it is not possible to establish global regularity by any “abstract” approach which only uses upper bound function space estimates on the nonlinear part of the equation, combined with the energy identity. This is done by…

🚀 Read this must-read post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: TL;DR: Metaphors like "a sinking ship" are often used to describe codebases, but are misleading. A business will sink long before code quality reaches a hypothetical floor. Technical debt has no bankruptcy, no clean reset, so metaphors that imply an end provide a false sense of security. Software is in the domain of the abstract. It is not like a building, or a bridge, that is in the physical realm where you can see and feel the nature of the thing. If you continue to…
