Between 2013 and 2015, Gaurav Bhatnagar and I wrote five columns for the math education journal At Right Angles (Azim Premji University) on mathematics and visual wordplay — specifically ambigrams. Across the five articles we explored symmetry, self-similarity, fractals, and paradoxes. You can download the combined PDF, or read the articles individually below.
