💻 The Finite Element Method (FEM) – A Beginner's Guide
In this blog, I am going to introduce the Finite Element Method without any heavy mathematical explanations and it is by no means a course on FEM - this is reserved for future posts.
🧠 Powerful ‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Astrophysicists modeled the solar system’s behavior in two ways. First, they used decades of NASA data to train a neural network. They then used a symbolic regression algorithm to further distill that model into an equation. In these videos — which show true positions as solid objects, and model predictions as wire mesh outlines — the neural network (left) does far worse than the symbolic regression algorithm (right).
💦 Can Quantum Fluids Explain Turbulence in Classical Fluids?
It is clear that Quantum fluid creates turbulence because of quantized vortices due to mutual friction by excitation. This leads to an effective kinematic viscosity that has the same units and scale as that of viscosity in classical fluids. But this is purely a numerical coincidence! Nonetheless, an important area to investigate.
💻 Engineering Tool of the Week – Lethe
Lethe (pronounced /ˈliːθiː/) is open-source computational fluid dynamics (CFD) software which uses high-order continuous Galerkin formulations to solve the incompressible Navier–Stokes equations (among others). Lethe contains a family of solvers that are based on deal.II, a finite element library. Through deal.II, Lethe uses Trilinos for its sparse linear algebra routines and p4est for its distributed adaptative quadtrees and octrees.
📚 Book of the Week
A Voyage Through Turbulence
Turbulence is widely recognized as one of the outstanding problems of the physical sciences, but it still remains only partially understood despite having attracted the sustained efforts of many leading scientists for well over a century. In A Voyage Through Turbulence we are transported through a crucial period of the history of the subject via biographies of twelve of its great personalities, starting with Osborne Reynolds and his pioneering work of the 1880s. This book will provide absorbing reading for every scientist, mathematician and engineer interested in the history and culture of turbulence, as background to the intense challenges that this universal phenomenon still presents.
