I’d be interested in hearing what the HN community thinks.
3blue1brown helped teach the "Computational Thinking" class at MIT using it: https://computationalthinking.mit.edu/Fall20/lecture2/
What I’m looking for when I talk about tools for thinking are the same type of sketching out a problem I do on paper. My first-year physics professor said (many years ago) that the way to start solving a problem is to make a well-labeled figure. I’m looking for something like MathCAD where you can label a figure with equations, or in COMSOL where you can start with a parametric description of a problem.
