The author was instilled with a passion for mathematics and physics by his father, who taught those subjects in a small Algerian town. Another indelible influence came during a high school mathematics class when his teacher gave the class a problem to solve. Little did the students know that it was Fermat’s Last Theorem, which stumped them, and before that, every mathematician since 1630. This experience taught the author that failing to get the final answer was part of learning. He became enchanted with imaging techniques and after earning his medical degree in Algeria, came to study at Johns Hopkins. There he received the training he desired in diagnostic radiology.
