Zvezdalina Stankova who comments on miss Cairo is on her own super out of the ordinary. https://math.berkeley.edu/~stankova/ https://math.berkeley.edu/~stankova/ Not only she did grow in Bulgaria during the most turbolent times of regime change from communism to democracy, but later graduates with a PHD from Harvard, and later becomes Director and Founder of the Berkeley Math Circle, and is also organizer of math competitions in Bay Area, and publisher of what seems to be a complete set of Math Books, carefully crafted with her peers from BG and presented here https://archi-math.com/ https://archi-math.com/ Curious whether miss Cairo was a student of hers or is to be.
