 >From Newtonian to ultra-relativistic gravitational scattering at 3rd post
 -Minkowskian order</a>\nby Gabriele Veneziano (CERN\, Collège de France) 
 as part of Quantum Gravity and All of That\n\n\nAbstract\nUsing the eikona
 l approximation for quantum scattering I will argue that the non-relativis
 tic (Newtonian) and ultra-relativistic (massless) limits of classical grav
 itational scattering are smoothly connected at 3rd post-Minkowskian (3PM) 
 order provided radiation reaction effects are properly taken into account.
  This is how a two-year-old puzzle raised by the first 3PM result by Bern 
 et al. was solved about a year ago. Extending the connection to the next P
 M order looks both important and non-trivial.\n
