Just discovered "Mathematics Made Difficult" (https://math.stackexchange.com/questions/1828660/what-are-the-prerequsites-for-this-book). It's a bit silly. But the potential!
"Simplicity is relative.To the great majority of mankind - mathematical ignoramuses - it is a simple fact, e.g., that 17x17=289, and a complicated one that in a principal ideal ring a finite subset of a set E suffices to generate the ideal generated by E. For the reader [...] the reverse is the case [...] Thus, the title of this book might equally well have been Mathematics Made Simple"
