General relativity has just celebrated its centenary and the early detection of gravitational waves by LIGO and Virgo has confirmed Einstein's prediction that accelerated masses can produce an oscillation of space-time spreading at the speed of light.
Written for all the curious minds, this book covers  all the ways to deal with  gravity : philosophical, historical and scientific , from quantum cosmology to dark matter and black holes.

A lecture will be given on this book by the authors in the Saclay Science Library on October 1, 2019 between 12:00 p.m. and 2 p.m

In this review Marc Barthelemy describes how statistical physics helps understand some of the key aspects of cities. Modelling the structure and evolution of cities became critical because policy makers need robust theories and new paradigms for mitigating problems arising with their growth. Fortunately, the increased data available about urban systems opens the possibility of constructing a quantitative ‘science of cities’ with the aim of identifying and modelling essential phenomena. Statistical physics plays a major role in this effort by bringing tools and concepts able to bridge theory and empirical results. This article illustrates this point by focusing on fundamental objects in cities: the distribution of urban population, segregation phenomena and spin like models, the polycentric transition of the activity organization, energy considerations about mobility and models inspired by gravity and radiation concepts, CO2 emitted by transport, and finally scaling that describes how various socio-economical and infrastructures evolve when cities grow. ...

Effective field theory is one of the deepest and most useful guiding principles in physics. Its tools and methods allow one to study the universal aspects of entire classes of unknown microscopic models, with their main features being captured by symmetries and few relevant parameters of the effective degrees of freedom. Because of its universality, it finds  applications across all scale in physics: from super-Hubble scales all the way to the Planck length. It is successfully applied to cosmology to describe the early cosmic inflation, the current cosmic acceleration, the dynamics of the large scale structure and the dark matter. Its methods have found recent applications in the theory of gravitational wave emission by binary inspirals, and in the new multimessanger astrophysics: new and conceptually compelling ways to perform calculations and predictions are being developed by making contact with the methods of scattering amplitudes of particle physicists. ...
