📚 Education is a progressive discovery of our own ignorance.
Hey friends & nerds! 👋
Welcome to the Sunday Science Newsletter – in this newsletter we explore & discuss strategies, systems & tools that help us become better, smarter and more effective scientists.

🧠 Learning governing physics from output only measurements
Extracting governing physics from data is a key challenge in many areas of science and technology. The existing techniques for equations discovery are dependent on both input and state measurements; however, in practice, we only have access to the output measurements only. We here propose a novel framework for learning governing physics of dynamical system from output only measurements; this essentially transfers the physics discovery problem from the deterministic to the stochastic domain.
The results obtained indicate the potential of the proposed approach in identifying governing physics from output only measurement.
💻 Engineering Tool of the Week – Semtex
Semtex is a 'classical' quadrilateral spectral element incompressible direct numerical simulation code that uses the standard nodal GLL basis functions to provide two-dimensional solutions and (optionally) Fourier expansions in a homogeneous direction to provide three-dimensional solutions. If your fluid mechanics problem is two-dimensional or has a natural periodic coordinate direction in 3D (a cylindrical coordinate system is perhaps the most obvious example), semtex could be a good choice.
📚 Book of the Week
Fluid Simulation for Computer Graphics
Animating fluids like water, smoke, and fire using physics-based simulation is increasingly important in visual effects, in particular in movies, like The Day After Tomorrow, and in computer games. This book provides a practical introduction to fluid simulation for graphics. The focus is on animating fully three-dimensional incompressible flow, from understanding the math and the algorithms to the actual implementation.
