Concerted voices
      on STRINGS
Quantum mechanics describes the world of the infinitely small, explaining the very special interactions at
particle level. Einstein’s theory of general relativity applies to the infinitely big, combining space and time
within a single entity (space-time) whose deformation explains the universal gravitational attraction between
the large galactic and stellar objects in the universe. The major challenge for contemporary physics is to make
the link between these two approaches and formulate a new unified theory – to which scientists have already
given the name ‘quantum gravity’. Initiated in the 1970s, the
development of the ‘strings’ mathematical approach is raising huge
hopes of achieving this. Explanations from Robbert Dijkgraaf, Professor
at Amsterdam University (NL), and from Brian Greene, Professor at
Columbia University (US), two of the guests at the Solvay Council who
spoke at the public conference that closed this scientific meeting.

Recognised as one of Europe’s leading
pioneers in the nanosciences and their
applications, Wolfgang Heckl has been
committed to the cause of sharing
knowledge and making it accessible to
all since a very young age. A long-
standing firm favourite with the
German media, today he is also known
outside national borders with a
reputation that, in 2004, brought him
the Descartes Prize for science

profile of a very warm and friendly
biophysicist who is Professor of
experimental physics at the Ludwig-
Maximilians University as well as Director
of Munich’s famous Deutsche Museum.

The added value
of mobility
Through its Marie Curie Actions, the EU makes a significant
contribution to the mobility of young people who are attracted to
research and want to make it their career. The annual Excellence
Awards – or ‘EXA’ for short – are part of this approach and are
awarded to researchers who seized the opportunity to work
beyond their national borders and made their mark at the highest
level of research in their field. At a ceremony in Dublin, in
December 2005, a scientific jury chaired by Jocelyn Bell Burnell –
the British astrophysicist who was involved in the discovery of
pulsars – named the five winners of the 2005 awards. Below are
brief profiles of these notable representatives of the up and
coming generation of European excellence.

Analysis of a stalled constitution
Like the Tower of Babel, it was at the
closing stages when the vast political
enterprise that was supposed to culminate
in a constitution for the European Union
ultimately failed, felled by a double French
and Dutch ‘no’ in their referendums. The
tortuous path that led to the text being
drawn up by the ‘Giscard’ Convention,
adopted at intergovernmental level after
a laborious process of introducing
amendments, and then launched perilously
for ratification in the Member States is an
experience that was studied ‘live’ and in depth by political science researchers with the DOSEI project.(1) They highlight
the conflicting and paralysing national preferences against which Europe has been struggling for more than a decade
in seeking desperately to define its goals and reform its functioning.
