His teaching uses a holistic approach that goes beyond just solving problems; he always emphasizes the importance of understanding the basic concepts and explains the connection between them. With his deep knowledge in Physics, Dr. Liu just knows how to get to a student's problems and fix them! Dr. Liu is not just sharp with the subject matter, he is also very patient and nice!
