Editorial

Beginning of September 2014, I attended the General Assembly of the
International Council for Science (ICSU) in Auckland, New Zealand. The
members of ICSU are national members and international scientific
unions. Together with Manuel de Leon, I represented IMU at this
General Assembly. Cheryl Praeger was also present, representing
Australia.
Elections of the coming Executive Board (EB) for the next three years
took place during the General Assembly. Three mathematicians were
elected on the Executive Board of ICSU: Daya Reddy (South Africa) is
the new President-elect (he will become President in 2017), John Ball
was renewed as regular member of the EB for the coming three years,
and Manuel de Leon was elected regular member of the EB: Manuel de
Leon just finished eight years on the Executive Committee of IMU,
during which he was the official representative of IMU at ICSU.
The International Council for Science is very little known among
mathematicians. To my opinion, ICSU deserves to be better known, and
this is why we will try to have a regular item on ICSU in each IMU
Newsletter. ICSU's mission is to strengthen international science for
the benefit of society. It promotes freedom and responsibility in the
conduct of science, and IMU often refers to ICSU's statements when
dealing with infringements to human or scientific rights. ICSU is also
very involved in science and policy to ensure that science is
integrated into international policy development. For that reason, the
General Assembly was preceded by a two-day "Science Advice to
Government Conference" (see http://www.globalscienceadvice.org/).
Also, ICSU has increased its involvement in supporting research on
understanding the planetary issues of climate change and
sustainability, adapting to them, and linking research on the matter
with policy. This has led to the creation of the 10 years initiative,
Future Earth, which is the flagship program of ICSU. The past
president, Yuan Tseh Lee, committed a lot of energy during his mandate
to do fund raising for supporting Future Earth. I discussed with Frans
Berkhout, the interim Director of Future Earth, and we are both
convinced that mathematical sciences have an important role to play in
Future Earth. The General Assembly is preceded by a one day meeting of
the scientific unions, which is an opportunity of meeting our sister
unions, learn about their activities and priorities, and start
networking for joint activities.
The General Assembly of ICSU contains some invited scientific
lectures. I was especially struck by the lecture of Nancy Bertler from
the Antarctic Research Centre of New Zealand. We regularly hear about
the sea rise during the 21st century. This rise has two origins: the
melting of glaciers and the thermic expansion of the oceans.
The melting of glaciers could produce an incredible amount of
additional water: if all Antarctica and Greenland's glaciers were to
melt, we could have a rise of the oceans of the order of 70 meters.
What saves us in the short term is that the glaciers cannot melt so
fast. But pay attention next time you hear the  forecasts of sea rise:
they never go past 2100! The lecture of Nancy Bertler dealt with a new
potential component of the climate change, namely the potential
"collapse" of Antarctica.
Because of the enormous weight of Antarctica's glaciers, most of the
floor of these glaciers is below sea level. Hence, there is a
potential of water penetrating under the glacier and causing the
breaking the big pieces that would end floating and hence, rise the
sea level. The recent studies conclude that such collapses could lead
to a sea rise of 4 to 8 meters before the end of the century, much
higher than the forecast of 0.5-1 meter rise in the last IPCC report.
All climate studies rely on mathematical modelling. We, as
mathematicians, develop tools to study models. But, what should be
included in the models? This is one of the big challenge of climate
science, which requires our collaboration with the other disciplines.

Call for nominations for the Program Committee of ICM 2018

The next ICM will take place in Rio de Janeiro in 2018.
The General Assembly of the IMU decided at its recent meeting in
Gyeongju, Korea, that "The IMU Adhering Organizations should be
invited to make suggestions for possible members of the Program
Committee.", see Resolution 7
at http://www.mathunion.org/fileadmin/IMU/Organization/GA/Resolutions/RESOL2014.pdf
The community is hereby invited to propose members for the PC for ICM
2018 and to forward them to IMU through an Adhering Organization.
Please note that members of recent Program Committees are not eligible
(a list of all former PCs can be found at
 http://www.mathunion..org/activities/icm/pc/).  Guidelines for the PC
are given
at http://www.mathunion.org/fileadmin/IMU/PC-OC-Guidelines.pdf.
A proposal should include a brief letter of recommendation as well as
a CV of the candidates [pdf-format only]. Candidates should not be
contacted prior to the nomination, as the composition of the PC
(except its chair) will only be made public at the ICM2018. The
deadline is March 1, 2015, and proposals should be sent by an Adhering
Organization to secretary(at)mathunion.org.

CEIC Notes and Comments: ArXiv millionth paper

A relatively quiet, but notable, milestone was celebrated this past
fall, as managers of arXiv.org at Cornell University counted the 1
millionth research article uploaded to the server. For mathematicians,
the arXiv preprint server is a vibrant resource, showing continued
growth in use by this discipline. Currently 28.8% of submitted papers
are in mathematics or mathematical physics, and 15.1% are in computer
science. More information on growth by topic at
 http://arxiv.org/help/stats/2014_by_area/index
Originally supported by Cornell University Library (CUL), arXiv has
moved to a collaboratively governed, community-supported resource.
Indeed, the growth of arXiv has led to new needs in underlying
 technology, as well as a plan for sustaining the service, which
requires permanent staff and a $1M budget.  In the new model,
effective January 2013, arXiv is supported by libraries and research
laboratories worldwide that represent arXiv's heaviest users, as well
as by CUL and by generous matching funds from the Simons Foundation.
See: http://arxiv.org/help/support
For a useful retrospective on these developments, a listing of the
Membership Advisory Board and Scientific Advisory Board of arXiv, as
well as a sketch of financials associated with the support structure,

International Year of Light and Light-based Technologies 2015

The United Nations have declared 2015, the International Year of Light
and light-based technologies (IYL2015):  www.light2015.org. The
Opening Ceremony took place at UNESCO on January 19-20 2015:
www.light2015.org/Home/Event-Programme/2015/Other/Opening-Ceremony.html.
The theme of light has many connections with mathematics and you could
consider using the opportunity of this international year to highlight
the contributions of mathematics in the study of light and its
applications. If you are inspired and decide to organize to organize
some event related to mathematics and light, then consider also
posting it on the IYL2015 website by clicking on "Submit an event" at
http://www.light2015.org/Home/Event-Programme.html.
Here are some relations between light and mathematics, from elementary
ones to be used in education to more advanced ones in research.
Fermat's principle states that the path of a ray of light between two
points is the path that can be traversed in the least time: this
principle unifies the laws of reflection and refraction. Mirrors
having the shape of conics and optical lens are sources of nice
mathematical problems. Optical fibers are now widely used in worldwide
communications. Interference between beams of light are at the origin
of iridescence. Mathematical modelling allows producing holograms with
laser beams. Laser filamentation, a nonlinear regime, has potential
applications in atmospheric remote sensing and lightning guiding. The
2014 Nobel Prizes in Physics and Chemistry were both related to light.
The Nobel Prize in Physics celebrated the invention of blue
light-emitting diodes, which has allowed bright and energy-saving
white light sources, thus contributing to energy saving. The
achievements of the winners of the Nobel Chemistry Prize allow to now
peer in the nanoworld.
