Main Question or Discussion Point
My teacher told me that elementary particles don't have position. Well, I don't understand this; it's like an oxymoron to me. Anyone with a easy-to-understand explanation?
Your teacher told you that the particles in QM (every particle, not only elementary) are fields and therefore in general have infinitely many positions. As interested_learner and ZapperZ explain to you, in the specific physical situation it may be just a single point in space(position). Today experimenters may show to you the detailed picture of the single electron/photon with any precision you will require.My teacher told me that elementary particles don't have position.
