What are the most fundamental particles of the Universe How do they interact with one another These questions will be addressed in this colloquium. In particular, the proton is a fundamental constituent of the atomic nucleus, one of the Universe’s most common particles and the fuel of stellar furnaces. However, many features of the proton, even its fundamental entities such as its mass, charge radius and spin are still not well understood. I will talk about why it is puzzling and how one may try to provide more in-depth picture on the internal structure of the proton and other fundamental matters in the Universe.
