always the same: there's all this math and I can understand that, but after many years of trying I have not found out what a "particle" supposedly is or that it exists.
particle is a unit excitation of its field or perhaps just a field of hat type, ok. unintuitive use of the word "particle" but we go with it.
then suddenly a particle is said to be somewhere and be travelling to somewhere. how is that possible?

I think there are two parallel cultures going on in high energy physics, and no one explains the connection
