Robert A. Black, Mathematical Storyteller

For most of my childhood, I lived right next door to Park Tudor School in Indianapolis, a lush, sprawling campus that used to be the Eli Lilly family's apple orchard and country retreat. My parents both taught there. As far as I was concerned, that meant we owned the place. My friends and I made up a Frisbee golf course around the campus. We went sledding on the hills in winter. We launched model rockets off the athletic fields. It was our back yard and playground for years. One time, my brother and I were invited to join a game of Capture the Flag some friends were planning to play on the campus after dark. The thought that such a game might not be a good idea never occurred to us. It was our back yard and our playground. Why couldn't we do it? Well, the police officers who showed up after about half an hour didn't see it that way. And they weren't impressed when I tried to tell them my parents worked there, so everything was all right. Imagine that! Th...

You don't have to watch anime for long before you encounter stories about yokai (also known as ayakashi ), the various ghosts and otherworldly creatures said to inhabit the Japanese islands, just beyond the range of normal human sight. Some of my all-time favorites feature them, including the long-running GeGeGe no Kitaro , currently in its sixth incarnation. A common feature in these shows is that the main characters often get into trouble and have to turn to some elder-figure - a grandparent or grandparent stand-in, usually - who knows the old stories about the creatures who lived with humans during the old times, before science and technology came along and drove magic away. That trope isn't unique to Japan, of course. It's been a regular feature in European stories too, and I expect it's in stories from Africa and other parts of Asia as well. Here in America, though, we have a problem. Here in America, any magical creatures from the old times wouldn't...

African-American mathematician David Blackwell's first teaching job was at Southern University, in Louisiana. When he arrived there in 1942, it was his first time living in the Old South, and his first time experiencing the Old South's Jim Crow laws. The first time he got on a New Orleans streetcar, he was fascinated by the little signs that plugged into the top of the seats, reading "White" on one side and "Colored" on the other. The idea was that the signs could be moved back and forth, depending on how many white people there were who needed seats. If, like me, you've never seen one before, just watch the episode "Rosa" from this year's Doctor Who season. Blackwell had never seen one before, either, and it amused him. When he got off the streetcar, he took it with him. In the oral history interviews he did for the University of California, Blackwell said, "I, of course, accepted segregation but I didn't take it very ...
