A teacher of his once said, "The pupil is also extraordinary, self-confident and always wants to excel." Werner Heisenberg excelled in math, physics, and religion in which he consistently received 1's (the equivalent of A's). The subjects that he did not fair as well in were German and Athletics which he usually received 2's (or B's). At the age of thirteen one of his teachers noted that his interests were moving to more "physical-technical things". This change in interests moved Heisenberg along the path from the geometry of objects into the realm of theoretical physics, especially the mathematical analysis of physical objects and data. As a pupil at the Gymnasium, he was intrigued by Einstein's theory of relativity and it's explanation. He later recalled that mastering the mathematics in Einstein's book gave him no difficulty. At the age of sixteen he tutored a 24 year old university calculus student to pass her final examination. Having no previous knowledge in calculus, he set out to teach himself so in turn he could teach the woman(by 1903 women were accepted to study at the University of Munich with the equal opportunities of men). During the three month time period he was able to teach the woman enough to pass her examination. Heisenberg said, "And in that time I didn't know whether she had learned it, but I certainly had." .
In the Summer of 1920 Werner Heisenberg graduated Munich's Maximiliams-Gymnasium and entered the University of Munich the following Fall. Not yet knowing which field of study he wished to commit to, his father arranged an appointment for Werner with Ferdinand von Lindemann, the professor of mathematics at the University of Munich. When he arrived for the appointment he saw the older professor sitting in his dimly lit office with his poodle hiding under his desk. When Heisenberg began to speak, the dog started to bark. For the duration of the entire conversation, the dog kept yapping.
