Well, I have two STEM degrees: Chemical Engineering and Biological Sciences.
I am refreshing my mathematics. I tutored math, biology, physics, and chemistry when earning my chemical engineering degree, and I hope to find some problems here that I can assist with.
Also, while refreshing, I am sure I will be asking for help too. My goal is to become proficient with OpenFOAM and Computational Fluid Dynamics (CFD). I will take much math on that route. I will likely use C++ and Python too.
