I once read a book on infinity that was written by an American female maths writer. Her writing was very easy to read and she was a great explainer of concepts. A very distinct aspect of her books was that there were only a few words on each line to assist with reading quickly. (For these reasons, I think the author and her works would be of interest to folks reading this site. Once this question has been accurately answered, I encourage you to check out her books.)
Can anyone tell me her name?
