For example, in a 2013 article for NOVA Don Lincoln writes:
Everywhere in the universe there is a field called the electron field. A physical electron isn’t the field, but rather a localized vibration in the field. In fact, every electron in the universe is a similar localized vibration of that single field.
He doesn’t really talk about where he came up with the word “vibration,” but uses it as if it’s a normal term. Is this a pop-sci metaphor, or is this a real thing? What solid intro to QFT can I read for a reliable translation of the science to a college grad who took two semesters of physics (basic Newtonian physics, and electromagnetism) ages ago?
Will such an intro likely use the word “vibration” and explain why we use that instead of “particle,” or is “vibration” a terrible approximation for the real concept, and a reliable intro would never use that term?
