From at least one, if not many more, perspective, I’m an old man, a somewhat established scholar. What could be more bizarre than wanting to quit everything else and spend six months learning all the math you wish you already knew? Apparently, I am not alone. Warren Henning, a software engineer, is doing much the same, and he explains his motives as follows in an essay on Medium:

To me, math is raw, untapped power. Statistics is helpful in computer programming, period. My dream is to learn the statistics, probability, and linear algebra needed to really understand machine learning and computer vision, which has had a major spurt of activity in the past 5–7 years. To realize this goal, I need a solid foundation so that I can truly understand what’s going on: why something works, when it won’t work, and what to do differently if it doesn’t.
