Information and Networks

Verlinde has taken a step ahead in understanding the role of Information in Physics. Several years ago Barabasi found out that networks were simpler than people thought. I bought his little book, Linked. I think he is up to something.

I feel like Information is not just positions of points in "emerging" space, whatever that means, but also the connectivity of those points matter. Simply put, most systems are not ideal gases, they have particle-particle interactions, and therefore they make connected networks. In classical physics, euclidean distance is important, but in quantum physics we encounter non-locality.

I believe that Information in physics is more like real gases, than ideal gases. Maybe the holographic principle is more non-local than local, and to be fair, Verlinde does point out in his paper that we should be in the lookout for non-locality.
