    tl;dr: A ’Short Stories’ paper, 3 pages. Considers Littlewood polynomials (each coefficient is +1 or -1) of degree n, and the patterns that arise from plotting the set of all roots for a particular degree. Note: Figures are plots of the complex plane, with the intensity proportional to the number of roots at that point. The plots resemble a unit circle with fractal patterns on the circle’s boundary. Subject area is outside of my regular reading; I enjoyed the article.
