This prediction seems intuitively strange: In the classical world, it is different. For example, the information contained in a book depends on its volume — not merely on the area of the book’s cover. In the quantum world, however, information is often closely linked to surface area. […]

Today, physicists expect quantum electrodynamics (as the quantum field theory of electromagnetism is called) to start diverging somewhere around the 137th term. That is, perhaps, a138x138 may be larger than a137x137, and including it in the sum will make the prediction less — rather than more — […]
