Just barely finished the first of (hopefully) 12 Jupyter Notebooks for self-study and experimentation in next semesters "Mathematics 3" Course. Although this will only be a single-shot lecture, I am having way to much fun building this (and, yes, nothing teaches better than teaching yourself). Well, I should be doing other stuff, but a day full of oral exams earned me this evening. This notebook, and probably most of those to come, is based on "Probability" by Jim Pitman. If you have a masto-link of him, please reply with it. I am simply to tired now. (Also, I have to hit my Norsk-lecture to not miss my streak before midnight.)
