Title : “Quasiparticles and Quasi-worlds”
We can use theoretical ideas and techniques that were originally developed to describe the world by building up from elementary particles to describe different forms of matter “from the inside”, as quasi-worlds built up from quasi-particles. We can also use them creatively, to imagine new possibilities. This line of thought has a glorious past, a thriving present and a brilliant future.
