No need for Euclidean geometry?
I once worked with an assistant on a software development project. Part of her responsibility was to write the routines to graphically depict the configuration of the thing we were modelling. Unfortunately, both her high school education (which, admittedly, was obtained in a third-world country) and post-secondary education precluded geometry, and she was hopelessly at sea with it. In the end, I wrote out the formulas for everything she needed to calculate, she programmed them without a glimmer of understanding, and we got through it. Just don't go telling me that Euclidean geometry "is only a 'basic' mathematical skill for a subset of STEM disciplines"; that's a crock.
