I solely used it in college, but heavily. I'm content with Python now. I never got into making my Mathematica notebooks super presentable, but I think Jupyter notebooks also fill that need really well now. Noteworthy projects: * Visualizing linkages in a car steering system, and then brute-force iterating on lengths of components to reduce bump-steer * Illustrating nuclear reactor core layouts (fuel rods, control rods) using "plotted" hexagons. I think I subsequently animated this to illustrate... something (Bummer I don't use my nuclear engineering learnings anymore). But in general, it was just a great tool at the time for engineering-oriented calculations and graphs. Matlab's syntax never appealed to me. Oh, and my absolute favorite thing was the interactive documentation that Mathematica had. Made trying new things super easy; search the docs, modify the snippet, and now you understand it!
