I Owe Black Canada
Coming to understand the real but not real border
"In a move that many told me was a major professional mistake, I dropped out of one of the best astronomy PhD programs in the United States to pursue research at the relatively new Perimeter Institute for Theoretical Physics, switching to the PhD program at University of Waterloo in Ontario, Canada. I had never heard of Waterloo, although I’ve come to understand that in math and engineering circles, it’s kind of a BFD, with the largest mathematics faculty in North America (multiple math departments!), and the most extensive engineering co-op program in North America."
