    Twenty years later, and still a fascinating topic!

    Under a variety of parameters (model states), geometries, initial conditions, and boundary conditions, I did a study on the stability of its equilibrium solutions (expressed in the unknowns $\rho, p, \mathbf{q}$). Even years after this initial research, three more papers appeared: one in 2008 (using Chebyshev Petrov-Galerkin with pseudo-arclength continuation to detect bifurcation points), one…

  • Computers to the rescue: unraveling the secrets of models

    The purpose of science is to explain what we observe around us, i.e., the universal system. [1] One fundamental toolkit for scientists are models. But what exactly is a model in science? I asked this question to Copilot, and I received the following answer: In science, a model is a simplified representation of a system…
