Laughlin published a book entitled ''
A Different Universe: Reinventing Physics from the Bottom Down'' in 2005. The book argues for
emergence
In philosophy, systems theory, science, and art, emergence occurs when an entity is observed to have properties its parts do not have on their own, properties or behaviors that emerge only when the parts interact in a wider whole.
Emergenc ...
