A friend sent me this graphic and I thought it was pretty funny, mainly because it's so true! Ironically, I never learned how to use Excel in school, or didn't even how to write a simple code. Excel is a great and powerful tool. I think you could group PowerPoint into that category too. Learn more about Matlab, CATIA, AutoCAD, Pro-E, and more over at my CAD Systems Help blog. I also find this engineering flow chart to be hilarious.
