How to make social cohesion work. Bertelsmann Stiftung Speech 2019
The megatrends of globalization and digitalization pose
challenges for social cohesion. Many people are concerned
about their economic future, and right-wing populists are
leveraging the internet to spread oversimplified messages
and fuel fears. Thought leaders from around the world
convened to discuss the future of social cohesion at the
Bertelsmann Stiftungâs international âTrying Timesâ
conference addressing the issue âRethinking Social
Cohesionâ that was held in Berlin from September 4â6,
2019. In his closing speech titled âHow to make social
cohesion work,â Canadian author and President Emeritus
of PEN International John Ralston Saul demonstrated
that empathy, respect for difference and the willingness to
accept the complexity of society rather than exclusion and
fear are the factors that pave the way toward a successful
future. The social cohesion of the future needs both
diversity and community. Read his speech in full here
Question Isotropy
The "cosmological principle" was set up early without realizing its
implications for the horizon problem, and almost entirely without support from
observational data. Consistent signals of anisotropy have been found in data on
electromagnetic propagation, polarizations of QSOs and temperature maps.
The axis of Virgo is found again and again in signals breaking isotropy, from
independent observables in independent energy regimes. There are no
satisfactory explanations of these effects in conventional astrophysics.
Axion-photon mixing and propagation in axion condensates are capable of
encompassing the data.Comment: Published in Axions 2010: AIP Conf.Proc.1274:72-77,2010, edited by

Exploring the Micro-Structure of the Proton: from Form Factors to DVCS
For a long time people made the mistake of thinking the proton was
understood. New experiments, ranging from form factors to deeply virtual
Compton scattering, promise a new era of highly informative studies. Among the
controversial topics of the future may be such basic features as the physical
size of the proton, the role of quark orbital angular momentum, and the
possibility of making "femto-photographic" images of hadronic micro-structure.Comment: 19 pages, 2 figures, presented by John Ralston at the Workshop on
"Testing QCD through Spin Observables in Nuclear Targets", University of
Virginia, Charlottesville, Virginia, April 18-2
