A Revolution in Disguise: The European Citizens' Initiative
The European Citizens' Initiative is a feature of the Treaty of Lisbon that many people have as yet to discover. However, even though it has often been criticized as being a kind of bogus participation that is no more than a placebo, it may well change the European Union, for it contains the seeds of a European public sphere and European parties. In this respect the initiative has already been a success

Inflation from String/M-Theory Compactification?
We present some exact scalar potentials for the dimensionally reduced theory
and examine the possibility of obtaining accelerating 4d cosmology from
String/M-theory, more generally, hyperbolic and flux compactification. In the
hyperbolic case, even in the zero-flux limit, the scalar potential is positive
for the 4d effective theory as required to get an accelerating universe, and
thereby evading the ``no-go theorem'' given for static internal space. When we
turn on the gauge fields as source terms at the cosmological background with
potential V\propto exp(-2c\phi), we find eternally accelerating cosmologies
when the 4d space-time is flat and c\geq 1, or hyperbolic and 1<c<\sqrt{2}.Comment: 3 pp. espcrc2.sty. Minor typos corrected and Ref. added. To appear in

Brans-Dicke geometry
We reveal the non-metric geometry underlying omega-->0 Brans-Dicke theory by
unifying the metric and scalar field into a single geometric structure. Taking
this structure seriously as the geometry to which matter universally couples,
we show that the theory is fully consistent with solar system tests. This is in
striking constrast with the standard metric coupling, which grossly violates
post-Newtonian experimental constraints.Comment: 8 pages, v2 with additional comment and reference
