phonon

Both materials have phonons that work in different directions.

Other kids had comic books and you had the world of vibrating phonons.

I didn’t even know what vibrations were, except in a very common sensical way, and I certainly didn’t know what phonons were.

It began with the concept that particles, phonons, were a description or consequence of things that you wouldn’t think of as particles but as vibrations.

In Fundamentals, you write about how, when you took a trip to Bell Labs in high school, you heard a scientist say that “phonons are the quanta of vibration,” and that that phrase just kind of reverberated for you.
