Hawking predicted that black holes should radiate
thermal radiation, the temperature being a function solely of the
geometry near the horizon of the black hole. The same arguments show
that one would also expect thermal radiation from other horizons, like
the sonic horizon formed in a transsonic flow, or the horizon to fluid
surface gravity waves formed by a blocking flow.
This talk will discuss the phenomenon of black hole thermal
emission, problems with its derivation, the ubiquity of such thermal
emission by horizons, and the measurements made in the past year of the
thermal spectrum of such radiation from a horizon for surface water
waves in a flume. Mot(s) clés libre(s) : Black holes, Hawking, Gravity

Combining the principles of general relativity and
quantum theory still remains as elusive as ever. Recent work, that
concentrated on the points of conflict and contact between quantum
theory and general relativity, suggests a new perspective on gravity. It
appears that the field equations of gravity in a wide class of theories
 including, but not limited to, standard Einstein's theory  can be
given a purely thermodynamic interpretation. In this approach gravity
appears as an emergent phenomenon, like e.g., gas or fluid dynamics. I
will describe the necessary background, key results, and their
implications. Mot(s) clés libre(s) : Gravity, General Relativity, Quantum Theory
