Notes from a book

I am reading Undiluted Hocus Pocus: An Autobiography of Martin Gardner, after learning a little about Gardner's fascinating variety of work and interest. He is most well known for his column called Mathematical Games, published in Scientific American for 25 years. There were a lot of mathematical theories and vocab that I had to look up, so I took notes while I read.

And now I am wondering about an English paper pieced quilt based on Penrose tiles (I am not the first)
