"Hi, I am Ken. I have a Ph.D. degree in physics from Brown University. I also have a BSc. in physics (with a minor in mathematics). I have accumulated about 10 years of experience in teaching different college physics courses (from Newtonian mechanics to quantum mechanics) and training high school students for the Physics Olympiad competition. During my postgraduate studies, I received various excellent TA awards. My background makes me very confident in teaching all levels of physics courses, calculus, differential equations, and other mathematical topics.

I always think that all students can do well in learning physics. Meanwhile, I find that many students are struggling in college physics courses. This is not your fault! What you need is a good teacher, who can explain the principles to you step by step and show you suitable examples that demonstrate how those principles work. If you want to enjoy your journey in learning physics, try to work and learn with me!" less...
