Introduction to John Hopcroft's Teaching Experience

John Hopcroft is a renowned figure in the field of computer science, known for his contributions to theoretical computer science and algorithms. Having taken two of his courses at Cornell University, I have had the privilege of experiencing his unique pedagogical approach and profound insights into the discipline.

Undergraduate Course: CS 481

CS 481 was a substantial undergraduate course that runs like clockwork, a testament to Hopcroft's automata theory. The book he co-authored on the subject is a standard reference in the field, and his lectures reflect his mastery of the material. The course was meticulously planned, and his in-depth explanations made complex concepts accessible and engaging.

Graduate Course: CS 683

Transitioning to the graduate level with CS 683, the experience was markedly different. This smaller, more specialized course allowed for greater flexibility and personalization. Hopcroft was highly responsive to feedback, continuously adapting the course to cater to the evolving interests and needs of his students. His dynamic lecturing style and openness to dialogue made for a truly enriching learning environment.

John Hopcroft's Continuing Influence

Today, as an experienced professional, it is heartening to see that Hopcroft continues to contribute to educational endeavors. His passion and dedication towards teaching have remained unwavering, regardless of the level of expertise of his students. If you are considering taking one of his courses, do not hesitate to do so. His teachings are invaluable and will undoubtedly enrich your understanding of computer science.

Reflections on Other Professors

Although I graduated from Cornell in 1996, I still had the opportunity to learn from another distinguished Turing Award recipient, Juris Hartmanis. His enthusiasm for teaching and his encouragement to solve problems by going for a walk are lasting impressions that have stayed with me. Hartmanis's advice to take a break and take a walk when stuck on a problem is a reminder that creativity and persistence are key to solving complex issues.

Conclusion

John Hopcroft's courses at Cornell University provide a unique blend of rigorous academic content and open pedagogical methods. His contributions to the field of computer science are immeasurable, and his teaching has left a lasting impact on many students. For those interested in gaining a deeper understanding of theoretical computer science, taking courses with Professor Hopcroft is an excellent choice.
