PhD physicist & Olympiad gold medalist offering physics and math tutoring for high school, Gymnasium and university level.

Ralph tutored me in physics, and I’d first like to start by saying that, thanks to him, I ended up getting a grade of 5.5! I had to repeat the first semester of medical school because of physics, and after working with Ralph, physics actually became one of my best subjects.

He explained the theory incredibly clearly and went through the exercises step by step. I could ask questions at any time, and I was also able to decide what pace we wanted to work at during our lessons.

The best thing about Ralph is that you can really tell how much he enjoys his work, especially physics. He is genuinely fascinated by the subject, and that enthusiasm was contagious. I actually looked forward to our lessons and to learning something new about physics. He showed me that physics is everywhere in the world around us!

I would highly recommend him to anyone looking for a great physics tutor.

Thank you so, so much!

Ralph and I lectured advanced quantum physics courses at ETH Zurich. Ralph is a natural teacher and mentor, and his knowledge of physics and maths is at the level of an ETH Professor. Ralph’s lectures were extremely clear and well-prepared. He took the time to explain complex concepts in accessible ways, and to answer students’ questions with empathy and patience, until he was sure he understood their problem and that they understood the answer. I can absolutely recommend him as a tutor!
