While teaching a math class, Nisse Greenberg is troubled by his student's name, and his own.

Nisse Greenberg is an educator and storyteller who eats mostly vegetarian. Sometimes he eats wings because wings are really good. When he applied for a visa to go to India he tried to type "atheist" into the proposed slot for religion, but he accidentally typed "matheist." He found it more appropriate anyway. He teaches high-school math to high-schoolers and math philosophy to adults. He creates art with spreadsheets and quantitative analysis. He also curates storytelling for The Tank, and hosts the shows Bad Feelings, VHS Presents, and Drawn Out Storytelling. Here is his playground: nissegreenberg.com
