Holographic Principle

To them, I Said, the truth would be literally nothing but the shadows of the images - Plato, The Republic (Book VII)

All of the information contained in some region of space can be represented as a `Hologram' - a theory which `lives' on the boundary of that region. - G. 't Hooft

Quantum Information and Gravity

"It from bit" symbolizes the idea that Information sits at the core of physics, and every "it", whether a particle or field, derives its existence from observations. - John A. Wheeler

Wheeler's vision is coming to fruition, with the twist that classical bits have given way to the qubits of quantum information theory -"It from qubit", Simons collaboration

Strongly Correlated Systems and Black Holes

Regarding "shear viscosity/entropy" of the quark-gluon plasma: a friend of mine in nuclear physics joked…. The first useful paper to come out of string theory- Dam Thanh Son
