1. EDITORIAL
Mikhail Leonidovich Gromov received the 2009 Abel Prize from His Majesty
King Harald at an award ceremony in Oslo on 19 May. Her Majesty Queen
Sonja also attended the award ceremony. The Abel Prize that carries a
cash award of NOK 6,000,000 (close to EUR 700,000, or USD 950,000), is
awarded by the Norwegian Academy of Science and Letters.
The Abel Prize is an international prize for outstanding scientific work
in the field of mathematics, including mathematical aspects of computer
science, mathematical physics, probability, numerical analysis and
scientific computing, statistics, and also applications of mathematics
in the sciences. The prize is meant to recognise contributions of
extraordinary depth and influence to the mathematical sciences. Such
work may have resolved fundamental problems, created powerful new
techniques, introduced unifying principles or opened up major new fields
of research. The intent is to award prizes over the course of time in a
broad range of fields within the mathematical sciences.
The right to nominate candidates is open to anyone. The Abel Laureate is
selected on the basis of the recommendation from the Abel Committee,
which is appointed by the Norwegian Academy of Science and Letters. The
Abel Committee is chaired by a Norwegian mathematician; the other four
members are selected based on nominations from the IMU (three seats) and
the European Mathematical Society (EMS) (one seat). Each member serves
on the committee for two years, except the chair who serves for four
years. By making nominations for the Abel Committee, the IMU and the EMS
play a key role in sustaining eminent standards for the Abel Prize. The
2009 Abel Committee consisted of Sir John Kingman, Sergey Novikov, Neil
Trudinger and Efim Zelmanov, together with the Norwegian chair Kristian
Seip.
This summer Springer will publish the book "The Abel Prize 2003-2007.
The First 5 Years" which will contain presentations of the first five
years of Abel Laureates. The book is edited by Helge Holden and Ragni
Piene.

2. NEWS FROM IMU
FINANCIAL SUPPORT FOR PARTICIPATION IN ICM2010
The International Mathematical Union (IMU) and the ICM2010 Local
Organizing Committee are currently making efforts to obtain financial
support to enable as many mathematicians as possible from developing
and economically disadvantaged countries to participate in ICM2010.
Applicants need not necessarily be from IMU member countries.
The IMU and the Local Organizing Committee have established three
different support categories (travel, registration, living support can
be applied for):
1) Young mathematicians from developing and economically disadvantaged
countries
2) Senior mathematicians from developing and economically
disadvantaged countries
3) Mathematicians from developing countries in Asia with emphasis on
countries neighboring India
All applicants must preregister (starting 15 May, 2009) at the
Congress website (www.icm2010.org.in) as the preregistration access key
will be required as the first step in the process of applying for
support. In all
cases, the permanent institution of the applicant must be located in a
country which is eligible for the corresponding category.
Mathematicians from countries which are eligible under category 1 or
category 2 (a list will be posted at the ICM2010 website) may apply
under category 1 or 2 but not both. Mathematicians from Asian
countries that are eligible under category 3 (a list will be posted at
the ICM2010 website) may apply under that category whether or not they
have applied under categories 1 or 2. However, the same type of
support (e.g. living) will not be granted to the same individual under
two different categories.
Mathematicians who do not fall within the three groups listed above
are asked to refrain from applying for this support.
All mathematicians who wish to apply for support are kindly asked to
complete the corresponding Application Form at the ICM2010 website
(the same form is used for all three categories). Applications may be
submitted from 1 JULY 2009 through 1 JANUARY 2010. The decision of the
Selection Committee will be communicated as soon as possible, after 1
May 2010. Queries may be sent to the organization of the ICM2010 at
the address

3. NEWS FROM THE DEVELOPING COUNTRIES STRATEGY GROUP (DCSG)
1) Mathematics in Africa: Challenges and Opportunities
A survey for the John Templeton Foundation
In the fall of 2007, the John Templeton Foundation requested the
Developing Countries Strategy Group of the International Mathematical
Union to prepare a brief report on the current state of mathematics in
Africa and opportunities for new initiatives to support mathematical
development.
65 institutions/individuals in Africa with broad experience in the
domain were invited to contribute to the survey. Conclusions drawn from
the study centered around four ideas, which may be useful for
institutions, governments, and other organizations desiring to help
strengthen mathematics in Africa:
(1) Enhancing mathematics and its contributions to development requires
simultaneous attention at all levels.
(2) One effective way to enhance mathematics development is through
research and education networks.
(3) Mathematically stronger countries in Africa, and governments and
organizations outside Africa desiring to contribute to continental
development, should support, rather than manage, the activities of
participating centers in Africa.
(4) The support of mathematical development should take account of
broader national and regional realities.
The full report is available on the IMU website at:
http://www.mathunion.org/fileadmin/IMU/Report/Mathematics_in_Africa_Challenges___Opportunities.pdf
2) Volunteer Lecturer Program
In the Editorial of IMU-Net 31 of September 2008, DCSG Chair Herb
Clemens described the CIMPA-IMU/DCSG-USNCM Volunteer Lecturer
Program. Upon reading this, Professor S.S. Okoya, Head of the Department
of Mathematics of Obafemi Awolowo University in Ile-Ife, Nigeria,
requested two Volunteer Lecturers to deliver courses on Real Analysis and
Algebra. In March of this year he hosted his first Volunteer Lecturer,
Dr. Michael Nakamaye, from the University of New Mexico, USA, whom he
would like to thank "for the enormous amount of energy and effort that
he contributed to the life of the students as well as members of the
Department and Faculty at large." The second volunteer will be Professor
Vladimir Vershinin (Universit?Montpellier II, France/Sobolev Institute
of Mathematics, Russia).

4. MATHEMATICS AND ASTRONOMY: A JOINT LONG JOURNEY
An initiative from IMU, IAU and CSIC.
Mathematics and Astronomy walked together for thousands of years.
Ptolemy, Copernicus, Galileo, Kepler, Newton are good examples of this
fruitful interaction between both disciplines. In medieval educational
theory, the "quadrivium" consisted of arithmetic, geometry, music, and
astronomy. More recently, the extraordinary works by Einstein with the
General Theory of Relativity give new insights to our vision of the
universe, in a wonderful cooperation of geometry and physics.
Topics like galactic and stellar dynamics, planetary atmospheres,
radioactive transfer, hydrodynamic and hydromagnetic problems,
statistical astronomy, celestial mechanics, cosmology, use
sophisticated mathematics. Modeling such huge and complex systems, as
galaxies or clusters of galaxies requires new computational techniques
provided by mathematics.
The symposium wants to show and stress these links with the occasion of
the celebration of the International Year of Astronomy IYA2009. It is
organized by the Consejo Superior de Investigaciones Cient韋icas (CSIC)
and the Universidad Nacional de Educaci髇 a Distancia (UNED) under the
auspices of the International Mathematical Union (IMU) and
the International Astronomy Union (IAU).
The symposium will have a special session in order to discuss the approach
of the astronomy to the mathematical education. Female researchers, young
students, and astronomers and mathematicians from developing countries
will be specifically encouraged to attend.

5. 7th PACOM
The 7th Pan-African Congress of Mathematicians will be held from Monday
3rd to Saturday 8th of August 2009 in Yamoussoukro, C魌e d'Ivoire under
the theme
"New trends in the Development and the applications of Mathematical
Sciences."
PACOM, which is a major scientific event for mathematicians in the
African continent and beyond, is organised every 4 years under the
auspices of African Mathematical Union in order to depict the state of
the art of mathematical sciences and to address issues of interest to
Africa, bringing together mathematicians from different countries,
specialities, backgrounds and ages.
This year's edition will be locally organised by the Soci閠?
Math閙atique de C魌e d'Ivoire (SMCI), with the active participation of
various Ivorian Universities.

1. EDITORIAL
Next week I will attend a workshop on the mathematics of weather and
climate prediction. It is a subject that I know very little about, but
which intrigues me as one in which mathematics can perhaps contribute
critically to a problem facing all humans. For example, the question
of which features of the climate are predictable seems to me to have a
deep mathematical component. In the present global financial crisis
we see both the potential of mathematical modelling to help
restabilize the world economy, and the possibility that complex
financial instruments created by mathematicians may have been one
element in precipitating the crisis itself.
Thus mathematics has the capacity to change the world. But it is not
more responsible or moral to work on mathematical models of the heart
than on, say, the Langlands programme. Leaving aside aesthetic
reasons, to argue thus would deny the value for future applications of
mathematics of the subject developing naturally according to its
intrinsic structure. Yet the choice of what problems to work on is one
of the most important that faces researchers, and the contribution
that mathematics can make to society is a legitimate consideration in
this choice.

2. NEWS FROM IMU
1. Visa problems
At the General Assembly 2006 in Santiago de Compostela, Spain,
the International Mathematical Union (IMU) adopted the following
resolution:
"The General Assembly of the IMU continues to endorse the principle
of universality expressed in the International Council for Science
(ICSU) ARTICLE 5 of the STATUTES, as adopted by the 1998 General
Assembly, and endorses the additional ICSU Statement on the
Universality of Science (2004) (see
http://www.icsu.org/Gestion/img/ICSU_DOC_DOWNLOAD/567_DD_FILE_Universality.pdf
).
Notwithstanding heightened tensions, security concerns, etc., the
General Assembly urges free exchange of scientific ideas and free
circulation of scientists and mathematicians across international
borders. The IMU opposes efforts by governments to restrict contacts,
interactions, access and travel in the world mathematical community,
particularly when such restrictions penalize individual mathematicians
for the actions of governments."
see Resolution 10 at
http://www.mathunion.org/Organization/GA/Resolutions/RESOL2006.pdf
ICSU has received a number of reports that some governments
make it difficult, e.g., due to security clearance issues, for
scientists to obtain visas in time to allow them to attend meetings.
The attached letter from ICSU's Deputy Executive Director Carthage
Smith is meant to alert scientists about this situation.
IMU asks all its adhering organization and all mathematical
societies to inform its members of this issue and contact
their governments in order improve this frustrating situation.

5. IMU ON THE WEB: Mathematical Notation on the Web
The Mathematics Markup Language (MathML) activity of the World-Wide Web
Consortim (W3C) grew out of the HTML-Math effort of 1994. Early work on MathML
paralleled the development of the eXtensible Markup Language (XML), and the
two influenced each other. MathML was in fact the first XML application: a
fact not surprising to those who practice the "Queen of the Sciences".
Mathematics uses a complex and highly evolved system of two-dimensional
symbolic notations. Indeed in traditional typesetting mathematics was known as
"penalty copy" because of the difficulty of the two-dimensional arrangements
and the large range of characters.
These challenges have translated into electronic world of browsers, both for
the two-dimensionality and the range of characters. Browsers have started to
develop, either directly or via various "plug-ins", the ability to handle the
two-dimensionality. The question of names for the large range of
mathematical symbols needed has been largely solved as a part of the
process which extended the Unicode standard to include symbols for other world
languages. The remaining challenge is the availability of what are known
as "glyphs", i.e. what the characters look like. Here it is must be
admitted that the situation is less satisfactory. Even if one has access to
the glyphs (and this is not always the case), it is rare that they match
the font of the ordinary characters in the surrounding text. This tends,
at the moment to lead to ugly but readable text on the web, as can be found
in the abstracts of many journals, as viewed by some browsers under some
configurations of fonts. It is the caveats in the last sentence that
indicate the problem: the publisher can have no idea what set of glyphs
will be chosen by the browser. However, the fact that we are discussing
"ugly" rather than "unusable" illustrates the progress that has been made,
and there is more work being done (under the auspices of STIX -
http://www.aip.org/stixfonts/) to solve these problems.
As pointed out in an early draft of MathML
(http://www.w3.org/TR/WD-math-980106/chapter1.html)
"The challenge in putting math on the Web is to capture both notation and
content in such a way that documents can utilize the highly-evolved
notational practices of print, and the potential for interconnectivityin
electronic media. "
This challenge means that MathML essentially developed two languages: one for
notation (Presentation MathML or MathML-P) and one for content (Content
MathML or MathML-C). It is worth noting that neither is intended for direct
human consumption: MathML-P will be written by editors and other software
tools, and rendered by browsers or printing engines, and MathML-C is
intended for direct production and consumption by software tools with a
deep capability to manipulate the mathematical meaning thus encoded. Hence
clarity and machine readability (parsing) take priority over conciseness.
MathML compresses very well!
With that caveat, MathML-P will seem familiar in concept to LaTeX users.
Perhaps the biggest difference is that a horizontal row is explicit in
MathML-P, So LaTeX's a+b becomes a row of (the MathML encodings of) a, plus
and b. The reader is referred to http://www.w3.org/TR/MathML/chapter2.html for
more detail and examples. MathML-P differs from LaTeX, though, in having
several operators that would render as white space on a printed page, such as
⁢ or ⁡, thus enabling a MathML-to-speech
renderer (they do exist, and seem to be remarkably effective) to distinguish
"f of x" from "f times x", even though both would print as "f x" (but with
differing spacing, again implied by the 'invisible' symbols).
We will come back to MathML-C in a later article.

Subscribing to IMU-Net ------------------------------------------------------------------------ 1. EDITORIAL Dear Reader, Last month I visited India, and among others, I was shown the site of our 2010 Congress in Hyderabad. I also attended a "Pre-ICM" Conference in Delhi. The ICM is the single most important event in mathematics every 4 years, and its organization, from the work of the local organizers to the Program Committee to the Prize Committees to the publishers of the Proceedings (and many others) is the most important task for our community. There is sometimes skepticism about the Congress, quoting its large dimensions (for a mathematics meeting), and the fact that a single participant will know only a small fraction of the other participants, and will be able to follow only a small fraction of the section talks. But if you talk with somebody from physics or computer science, or from other branches of science, he or she will be envious of the fact that we mathematicians have such an event, where we can listen to carefully chosen speakers describing the latest developments, where we can award our most important prizes, have panel discussions about important issues, etc. The Fields Medal and the Nevanlinna Prize themselves are unique in their scope: they award the highest recognition not to old people whose work is known and well recognized already, but to young people and new results, thereby calling the whole community's attention to these young mathematicians and their achievement. Before I left for my trip to India, several friends wondered about such a trip, mentioning all sorts of dangers from snakes to malaria. If you recall, the particular time was also burdened by the terrorist attacks in Mumbay, and indeed quite a few participants of the conference cancelled their trips. Needless to say, the terrorist attacks had no influence on my visit, except for some increased security at public buildings. And with some caution, it is easy to avoid infections. And India is a country where crime, especially violent crime, is rare. And it is a country of fantastic sceneries, buildings, and people. So I can recommend visiting India very warmly to everyone, and hope to see you at ICM 2010 in Hyderabad! Laszlo Lovasz ------------------------------------------------------------------------ 2. IMU ON THE WEB: THE DIGITAL LIBRARY OF MATHEMATICAL FUNCTIONS The Digital Library of Mathematical Functions (DLMF) is a new reference work modeled on the highly referenced 1964 Abramowitz and Stegun Handbook of Mathematical Functions. Its 36 chapters, which survey current knowledge about special functions, were written by distinguished experts, validated by other experts, and supervised by the NIST editorial board, consisting of Frank Olver, Dan Lozier, Ron Boisvert, and Charles Clark. The DLMF is scheduled to appear later this year in a print version, as well as to be released as a free public Web resource at dlmf.nist.gov, which currently contains a preview of 5 of the chapters. Among its distinguishing features are references to available software instead of voluminous numerical tables, inclusion of recently established properties, coverage of special functions not previously represented, and extensive and innovative two- and three-dimensional graphics. Motivated by the Web's potential to radically change the way mathematics is disseminated and used, the DLMF project has inspired NIST to develop new techniques and software for semantically marked-up representations of mathematical formulas, mathematically aware search, and mathematical graphics. These innovations were designed to be used in the DLMF, and also serve as models for similar developments in other areas of mathematics and its applications. LaTeX was designed to produce beautiful mathematical documents, but lacks means of encoding semantics, that is, the mathematical meaning of the symbols on the page. Since one of its long-term goals is full semantic markup, the DLMF became one of the first large projects to commit to preparing its entire Web site in XML/MathML, which is specifically designed to provide superior rendering of type-set math (the Presentation form of MathML) as well as the encoding of semantic math (the Content form of MathML). To generate the XML/MathML from the LaTeX source, Bruce Miller, the DLMF's information architect, undertook the task of developing a suitable processor, named LaTeXML. It soon became clear that LaTeXML had much wider potential applications. For example, in a joint project with Jacobs University in Bremen, LaTeXML has been applied to more than 400,000 documents in the preprint archive at arxiv.org. For more information, see dlmf.nist.gov/LaTeXML. Another goal of the DLMF project was to develop a more powerful mathematical search engine, beyond simple bibliographic queries such as author, title, and keywords. In collaboration with Abdou Youssef of George Washington University, NIST undertook a project to provide for search within the DLMF based on queries that contain math fragments. Examples are Ai ^ 2+Bi ^ 2, for formulas containing a sum of squares of Airy functions, int_0 ^ infinity BesselJ, for infinite integrals with the J-Bessel function of order zero in the integrand, and int ? ^ ? for finite or infinite integrals whose integrand contains any variable raised to any power. As with the LaTeXML processor, the mathematical search engine has the obvious potential for applications far beyond the DLMF. For more information, see dlmf.nist.gov/help/search. Dan Lozier and Peter Olver ------------------------------------------------------------------------ 3. HYDERABAD ICM 2010 POSTERS The organizers of the ICM 2010 have produced three posters to advertise the next International Congress of Mathematicians which will be held in Hyderabad, India on 19-27 August 2010.

IMU ON THE WEB: Access Grid: enabling e-Collaboration Access Grid "Video-conferencing" covers a broad range of functionalities from basic two way use of video and audio for meetings to include document cameras, data exchange, desktop sharing, recording and shared applications (such as interactive whiteboards). Many versions, mostly commercial, of video-conferencing are available running in specially equipped rooms or on desktops/laptops. The Access Grid, AG, developed at Argonne National Laboratories (see http://www.accessgrid.org), has been described as video-conferencing "on steroids": it's free, scalable to many Access Grid Rooms, AGRs, and flexible. AGRs run under Windows, UNIX or Mac environments. There's no typical AGR (for a photo gallery, see http://www.accessgrid.org). However AGRs usually have a "wall": one large projection screen of three (or four) linked computer projection screens. There's usually one audio stream and video streams from three cameras. Working on 2 screens Many presenters work with two screens (with other screens used for video of remote audiences etc). One screen displays the main presentation (pdf slides, say) and one screen displays software demonstrations or "Digital Ink": handwritten asides, worked examples or sketches. How Digital Ink is provided depends on the hardware and software used. Since the AG uses VNC for the data/software stream, the presenter chooses to enable, or not, remote control: remote collaborators can take over the mouse and control the software (Maple, Word, etc). PIGs The AG software can run on a desktop/laptop: it's free and all that's required is a web-cam, headphones with a microphone and good internet connection, resulting in a Personal Interface to the Grid, a PIG. Canadian seminars For three years, led by Simon Fraser University and Dalhousie University, about 90 regional and coast-to-coast seminars, in mathematics and computer science, have been conducted via a network of Canadian AGRs [1]. In Australia ICE-EM (the education arm of the Australian Mathematical Sciences Institute, AMSI), is coordinating and partially funded 11 AGRs, in mathematics precincts in Australia. Most of the 38 universities in Australia have access to an AGR. In December 2007, an AMSI one-day seminar on engineering mathematics education had 16 remote AGRs participating. Using AGRs to collaboratively teach Honours (that is, 4th year) mathematics and statistics courses commenced in July 2006. During 2008, 17 courses were offered (see http://www.ice-em.org.au and follow the links Access Grid > Subject and Course List). Students, with the approval of their home university, can take courses for credit toward their Honours degree. All AMSI member universities are invited to participate. The UK Six centres in the UK, funded by the EPSRC, commenced (in October 2007) the teaching of "broadening" courses for PhD students. Two of these centres use AG technology: the MAGIC consortium of 15 universities (see http://www.maths.dept.shef.ac.uk/magic/index.php) and the Taught Course Centre: a collaboration between the Universities of Bath, Bristol, Imperial, Oxford and Warwick (see http://www.tcc.maths.ox.ac.uk). Conclusion The Access Grid enables very rich multi-nodal remote collaborations in research and teaching. Likewise, it is also an excellent and travel-reducing way to run a variety of administrative and planning meetings. The mathematics community, in Australia, the UK and Canada, is leading the way with collaborative teaching of advanced mathematics or seminars across networks of AGRs [2].

PASSING AWAY OF PROFESSOR KIYOSHI ITO Kiyoshi Itô died on November 10, 2008, at the age of 93. Kiyoshi Itô was one of the great figures of probability theory in the twentieth century, along with A.N. Kolmogorov and P. Lévy. Itô's most famous mathematical contribution is his invention of stochastic integrals, which were initially motivated by the theory of stochastic differential equations. The celebrated Itô formula gives an expression for a smooth function of Brownian motion, or of more general random processes, in terms of stochastic integrals. Itô's stochastic calculus has had an enormous impact in theoretical probability, as well as a huge number of applications in domains such as mathematical finance. For the latter reason, Kiyoshi Itô was awarded the first Gauss Prize of IMU at the 2006 ICM in Madrid. ------------------------------------------------------------------ 6. ICSU BOOKLET The International Council for Science (ICSU) endorses a new booklet on Freedom, Responsibility and the Universality of Science. In the light of recent high profile cases of scientific misconduct, the General Assembly of the International Council for Science (ICSU) reaffirmed the universal values that should guide the conduct of science. The Assembly also explicitly recognised the key social responsibilities of the scientific community as laid out in a new booklet, which will be made widely available to scientists across the world. The booklet asserts that: "all scientists have a responsibility to ensure that they conduct their work with honesty and integrity; and to ensure that methods and results are reported in an accurate, orderly, timely and open fashion." The booklet and more on the General Assembly are available at: www.icsu.org/3_mediacentre/GA_29.html ----------------------------------------------------------------------- 7.

Editorial 2. IMU on the Web 3. Emmy Noether lecturer 4. Sad news about Ibni Oumar Mahamad Saleh 5. Subscribing to IMU-Net ------------------------------------------------------------------------ 1. EDITORIAL A year ago two lecturers were sought to participate in the beautiful project of the French organization CIMPA (Centre International de Mathématiques Pures et Appliquées) to help rebuild the mathematics infrastructure in Cambodia. The context of this work was described to potential volunteers as follows: "We seek lecturers for intensive 3-4 week courses at universities in the developing world, at the advanced undergraduate level. The lecturer would be assisted by a local mathematics professor who prepares the students beforehand, assists when necessary during the course, and takes care of any necessary follow-up. These courses should have a student audience of 20 or more, be controlled, with examinations, and be part of a regular degree program at the university at which they are offered. Past experience in the developing world is desirable but not necessary. However what is required is tolerance for working in circumstances of modest resources, unexplained inefficiencies, and limited physical comforts. Funds for all expenses, including travel, will be provided; however, we request that the mathematician's home institution offer leave with pay during his/her 3-4 week absence. We believe that a strong case can be made that cooperation with this program will not only bring personal and professional benefit to the lecturer, but will also redound to the credit of the lecturer's institution." 40 volunteers immediately responded! Such an outpouring of interest in contributing to the formation of students of mathematics in the developing world could not be ignored! The Developing Countries Strategy Group of the International Mathematical Union, in cooperation with CIMPA and the U.S. National Committee for Mathematics, have built on that nucleus of 40 volunteers to launch the "Volunteer Lecturer Program" (VLP), whose goal is to provide mathematician volunteers to give intensive month-long courses at universities in the developing world. The program is quite modest in size due to the limited financial resources of the sponsoring organizations. But mathematicians interested in participating in the VLP, universities in the developing world interested in hosting lecturers to teach in the context described above, and, as importantly, donors desiring to provide the E.3000 necessary to support a VLP lecturer, should contact: Sharon Berry Laurenti Administrative Secretary Developing Countries Strategy Group of the International Mathematical Union e-mail: cde@ictp.it Herbert Clemens Chair of the DCSG ------------------------------------------------------------------------ 2. IMU ON THE WEB: Preserving our History The use of TeX over the last decade and a half to write papers, lecture notes and even ephemera has moved from the unusual to the commonplace. Indeed, some of my younger colleagues can't remember using anything else but TeX to write mathematics. For those of us somewhat longer in the tooth, we remember using other software, which was preceded by the little golf balls that allowed typing of mathematical symbols, which in turn was preceded by writing in the mathematics by hand (with the hope that the typesetting would introduce only a few errors). One of the happier results of this migration to TeX has been the ability to put our papers on personal web pages so that anyone with a standard computer configuration can acquire them. This usually means making a pdf or a PostScript file available for download. The little postcards that were mailed to request reprints has now joined those little golf balls as historical curiosities. Happily, the papers that were written in the predigital era are not beyond redemption. They, too, can and perhaps should be made available for download. In the past several years there have been significant advances in the ability to scan paper documents. With the right equipment, scanning several hundred or even a thousand pages is not difficult. The are two approaches, both of which work well. The first is to use a standalone scanner. Robust models with document sheet feeders are available for under $1000. These include the software for doing the scanning. There are lots of options when using such software, so here are some suggestions. When scanning the pages, the software can produce colour, grayscale or black and white files. Unless there is a compelling reason, black and white is usually the best choice for older documents. There is also a choice of resolution: 200, 300, 600 or 1200dpi (dots per inch). Usually the 600dpi is the best choice. There are also several different types of files that can be produced by the scanning software. All of them have some compression: these come in two types: lossless (no data lost during the compression) and lossy (some data irretrievable). A lossless compression is the best. There are also different file formats, the most common being pdf and TIFF. The pdf files are the ones to put on your web page; they can be read on any modern computer with readily available software. Note that there are two different types of pdf files: ones that are image only and those that are also text searchable. The latter type is preferable, and most scanners can produce them. There is also a compelling reason to keep lossless TIFF files. Newer and smarter software will emerge that will do things we can't do today. If you keep the TIFF files, there will be no need to rescan since the information is already in an industry-standard format. A second approach is to use a photocopier. Many of them come with scanning software built in: you feed in the pages and the image files are emailed back to you. Usually there are fewer options than with a scanner. The default resolution is usually 200dpi, so be sure to set it to 600dpi. The provisos given above for scanners are also valid for photocopiers. I recently carried out a two-month project that involved scanning of some 53000 pages. It really wasn't difficult. In fact the hardest part of preserving your mathematical history may be taking the staples out of those old pages. Our mathematical history is important and worth preserving. A bit of effort by all of us can produce a significant body of mathematical literature. Let's get our history out of the file cabinet and onto the web! Michael Doob Member of CEIC ------------------------------------------------------------------------ 3. EMMY NOETHER LECTURER: for ICM 2010 in Hyderabad Emmy Noether was one of the great mathematicians of her time, someone who worked and struggled for what she loved and believed in. Her life and work remain a tremendous inspiration. The 2010 Emmy Noether Lecture will be presented as a plenary lecture at the International Congress of Mathematicians in August 2010 in Hyderabad, to honour women who have made fundamental and sustained contributions to the mathematical sciences. There have been Emmy Noether Lectures at four previous ICMs, and this will be the second time that the selection of the Emmy Noether Lecturer has been made formally by the IMU. The IMU Executive Committee has established a committee of five, chaired by Cheryl Praeger (Australia), to select the 2010 Emmy Noether Lecturer. The committee will conduct their work over the next 6-9 months, and suggestions for consideration by the committee may be sent to Cheryl Praeger at praeger@maths.uwa.edu.au ------------------------------------------------------------------------ 4. Sad news about Ibni Oumar Mahamat Saleh Following the report of an independent enquiry on the events that took place in the Republic of Chad between January 28 and February 8, 2008, the French professional societies (SFdS, SMAI, and SMF) have notified the IMU that almost certainly Ibni Oumar Mahamat Saleh died in detention a few days after having been kidnapped from his home on February 3rd, 2008 by the armed forces of Chad. Ibni Oumar Mahamat Saleh, Professor of Mathematics at the University of N'Djamena was instrumental in the establishment of higher-education exchanges between France and Chad. He was one of the leading figures in the democratic opposition to the government of Chad. For more information and to continue demanding the truth on the fate of Ibni Oumar Mahamat Saleh, please go to: http://smf.emath.fr/PetitionSaleh/ ----------------------------------------------------------------------- 5.
