Dr Ghoussoub replacesDr Robert Moody who has led BIRS through its difficult initial stages.Dr Ghoussoub is presently Professor of Mathematics and “DistinguishedUniversity Scholar” at the University of British Columbia. He is the found-ing Director of PIMS (1996–2003), a co-founder of MITACS (Network ofCentres of Excellence in Mathematics of Information Technology & Com-plex Systems) and a member of its Board of Directors for the period 1998–2003. He is also a co-founder of BIRS and was Chair of its executivecommittee for the period 2000–2003.See New BIRS Scientific Director on page 5Nassif GhoussoubAlejandro Adem PIMS Deputy DirectorPIMS is pleased to announce the appointment of Alejandro Ademas PIMS Deputy Director effective January 1, 2005.  Until thenManfred Trummer will continue as Deputy Director.Professor Adem is a very distinguished topologist who has madeimportant contributions to the study of group actions and to thecohomology of finite groups.  He received his Ph.D. fromPrinceton University in 1986.  He was the Szegö Assistant Pro-fessor at Stanford University (1986–89) and a member of the Institute for AdvancedStudy (1989–90) before moving to the University of Wisconsin-Madison.He has held visiting positions at MSRI (1990), ETH Zurich (1993–94), Max PlanckInstitut Bonn (1997–98), University of Paris VII (1998), CRM Barcelona (1998), Univer-sity of Paris XIII (2000), and Hong Kong University of Science and Technology (2001).VIGRE Award to the University of WashingtonThe University of Washington (UW) has been awarded a five-year grant totalingUS$3.9M by the National Science Foundation (NSF) under the VIGRE programof the NSF Division of Mathematical Sciences.See New Deputy Director on page 3See VIGRE on page 4Contributed by Gunther Uhlmann, PIMS-UW Site DirectorAlejandro AdemThe scenic photographs in this magazine showcase some of theexceptionally beautiful surroundings of the various PIMS sitesVol. 8, Issue 12Director’s NotesCall for Scientific Proposals in the Mathematical SciencesPIMS now welcomes applications for support for conferences, workshops, seminars and related activities in the Mathematical Sciences, tooccur after April 1, 2005.  PIMS also invites scientists of PIMS universities to submit letters of intent for a period of concentration of aPIMS Collaborative Research Group.The deadline for applications is October 15, 2004. The results will be announced by January 31, 2005.For more information please see: http://www.pims.math.ca/opportunities/proposals.html.Ivar Ekeland, PIMS DirectorWhat do we have to show for the 2003-04 aca-demic year? First and foremost, the science,of course. Since April 2004, we have sevenPIMS Collaborative Research Groups simulta-neously working in periods of concentration, and26 post-doctoral fellows at the PIMS universi-ties. This has been generating a lot of scien-tific activity at the PIMS sites, and it has alsobeen attracting a lot of attention. Several promi-nent research institutes in mathematics aroundthe world are inquiring about the possibility ofassociating themselves with PIMS.While Ben Green was a post-doctoral fel-low at PIMS, he and Terry Tao have obtaineda remarkable result on prime numbers (seeGreen’s article in this newsletter). This is a tes-timony to the quality of the research at PIMS,and the excellent post-doctoral fellows we aregetting.We must continue to work hard to keep themomentum, and put every effort into quality tomake PIMS a leading research institute in theworld. To do this, we will be helped by the suc-cess of the Banff International Research Sta-tion, which is now almost through its secondyear of operations. BIRS is a huge success,and all the PIMS universities are benefiting fromits prestige and the fact that BIRS is attractingmany excellent mathematical scientists to theCanadian West. Again, we must work hard tobuild up and maintain the reputation of BIRS.This will be done by being uncompromising onquality, by being proactive in seeking out prom-ising developments of mathematics, and by im-proving the research conditions at the BanffCenter (for instance, by developing on-line li-brary resources). We are fortunate to haveNassif Ghoussoub as a Scientific Director ofBIRS, who will impart his energy and vision tothat task.It is also very good news for us that federalfunding for MITACS has been renewed for asecond seven-year period. This will certainlybe of help to PIMS in our own efforts to de-velop industrial projects. We all know how im-portant it is, for our research and for our stu-dents, to have good industrial contacts, and howdifficult and time-consuming it is to establishand maintain them. PIMS has succeeded indoing so, as the GIMMC and the IPSW havedemonstrated every year, but at a huge cost intime and effort. We are confident that MITACSwill help us overcome that barrier, and assistus in exploring new directions. The appointmentof Gary Margrave as PIMS Industrial Facilita-tor fits into that strategy.Other good news comes from the South.The University of Washington, which hasworked with us informally but closely for severalyears, has recently been awarded a prestigiousVIGRE grant (see this newsletter), and closercooperation with PIMS was a key element inthe grant application.PIMS had another very busy summer withnumerous conferences, workshops and summerschools. Special thanks go to the organisers ofthese events, and to the staff at all PIMS sitesfor their invaluable support. I would also liketo mention the many educational events thathave taken place during the year. PIMS per-sonnel have put an extraordinary amount ofenthusiasm and energy into organising theseevents, and they are indeed an important com-ponent of our mission. I am also pleased toannounce that PIMS is making a special efforttowards the First Nations, and that we will berepresented at the upcoming Provincial Con-ference on Aboriginal Education.Since June, scientists at PIMS-UBC havetaken advantage of the newly added space atour Central Office. I wish to thank UBC fordoubling the space available to PIMS. For thoseof you who know the PIMS site at UBC, wenow have expanded into the first floor, and wehave an interior staircase joining the first andsecond level, in the best mathematical tradition.We also have a new lecture/meeting room, anda small library. During the building period, therewas some disruption, as you may easily guessand as the pictures illustrate.I hope you enjoy this newsletter. Manythanks to Heather, Stefanie and Manfred forputting it together.PIMS-UBC Site Renovations: The new lecture room (left), and the interior staircase (right).Fall 2004 3In addition to the appointment of AlejandroAdem as Deputy Director, PIMS is pleased toannounce the following:New Board of DirectorsThe five founding universities have appointed rep-resentatives as follows: Bruce P.

The banquet celebrated one of many legacies of BarryMcBride: His defining role in the remarkable development of the mathematical sciences inwestern Canada during the last decade.Barry McBride recently finished his term as Vice-President Academic and Provost ofthe University of British Columbia completing several decades of dedicated service toUBC and to Canada, both as an inspirational leader and as a tireless advocate for Canada'squest for academic excellence.Notable among Barry's many achievements are his crucial contributions to the successof the mathematical science community in BC and Alberta with its hugely positive impact inthe rest of Canada and the Pacific Northwest. Barry's leadership and unwavering supportwere instrumental in the creation of the Pacific Institute for the Mathematical Sciences(PIMS), the MITACS Network of Centres of Excellence, the Banff International ResearchStation (BIRS), as well as in the emergence of UBC’s mathematical science community toa position of worldwide prominence.VIGRE grant to UWThe main goal of VIGRE is to attract andretain more US citizens and permanent resi-dents into the mathematical sciences at alllevels.  This award builds on the accom-plishments of a previous VIGRE award tothe UW in 1999, one of the first given, butat a level that is nearly double that of theprevious award.  The competition was keen:out of 29 proposals only three were funded.Dinner speeches celebrating the contributions of Barry McBrideTop row: John Waterhouse, VP Academic at SFU; John Hepburn, Dean of Science, UBC withNassif Ghoussoub; Indira Samarasekera, VP Research at UBC.Second row: Arvind Gupta, Scientific Director of MITACS, and Ivar Ekeland, Director of PIMS;Barry McBride; Nassif Ghoussoub, BIRS Scientific Director, MC for the event.Last row: Ivar Ekeland and Barry McBride; Barry McBride, John Waterhouse and Ken Foxcroft(former Board Member of PIMS).

Snaith(Southampton)Fall 2004 7In the spring of 2004, tucked in between work-shops on mathematical logic and foundations,manifolds and cell complexes, Fourier analysis,numerical analysis, probability theory and sto-chastic processes, mechanics of particles andsystems, game theory, economics, social andbehavioural sciences, dynamical systems andergodic theory, and quantum theory, BIRS heldits second five day experimental workshop oncreative scientific writing. The first took placein September, 2003. Curious colleagues haveasked us, and continue to ask, what these work-shop were like and what they accomplished. Inthe self-interview that follows, we address theseand other questions.Why hold workshops on creative scientific writ-ing at BIRS or anywhere else? Mathematics is anart form, so isn’t mathematical writing creative?Alas, the population that recognizes the creativ-ity in a mathematical or scientific paper is smallerby many orders of magnitude than the numberwho remember their Latin. By creative scientificwriting we mean something else: mathematicaland scientific ideas as subjects for poetry, drama,short stories, novels, nonfiction, comic books,essays, and film.Why would anyone write about science and math-ematics in this way?  Does anyone do it?Mathematics is part of world culture, part ofthe human spirit. It’s as fit a subject for art,music, and literature as any other. As for who,some mathematicians write poetry, fiction, non-fiction, or drama. And there are non-mathemati-cian poets, fiction writers, nonfiction writers anddramatists whose work engages mathematiciansThe Creative Scientific Writing Workshops at BIRSAn interview with and by the organisers: Marjorie Senechal (Smith College) and Chandler Davis (University of Toronto)and mathematical ideas. Our first workshop hadfifteen participants, all highly accomplished, andthe second had twenty, ditto.But aren’t you mixing apples and eggs?Talk about mixing! But, with garlic and salt,apples and eggs make an excellent omelet. Weassumed from the start—and now we firmlybelieve—that non-mathematicians who writecreatively about mathematics and mathematicians,and mathematicians engaged in creative writing,have a lot to teach and learn from one another.Okay, but isn't it confusing to mix all those liter-ary genres?On the contrary! Creative writing is oftensparked by cross-genre insights. For example,in our workshops a poet helped a fiction writerfind a better way to tell the end of his story. Amathematician nonfiction writer helped a dra-matist extend the ideas of her play, ideas a film-maker sitting in on their discussions recast in dog-gerel form. A novelist had insightful comments onpoetry. Of course, it helped a lot that we pressedeveryone to circulate his or her work in advance.By the time we arrived in Banff, we’d read it all,thought about it, and were eager to comment.Why should BIRS take the lead in encouraging this?Call it “outreach” if you like, part of the largereffort of mathematicians everywhere in thesedays of dwindling funds to explain who we areand what we do — and why it matters. Or, ifyou prefer, an effort to engage scientists andmathematicians in a wider world of discourse.The need to create a body of literature aroundmathematics and science is widely acknowledgedby mathematicians and non-mathematicians alike.But is there an audience for cre-ative scientific writing, as youdescribe it?The popularity of plays likeProof and biographies like ABeautiful Mind and The ManWho Loved Only Numbersshow that there's a large andgrowing public eager to sharein the great ideas of mathemat-ics and science. The creativewriter’s job is not to coercethem to eating these things likemedicine hidden in jam, but toconvey these ideas through lit-erature instead of formalism.Yet except for obvious examples, like those youcited, creative writing about the content of math-ematics is extremely rare and creative writingabout the activity of mathematical creation iseven rarer.That’s why we organised the workshops: toencourage practitioners who engage this contentin their work. To give them opportunities todiscuss important issues, to learn what othersare doing, to encourage each other, to critiquecurrent work, to welcome young writers intothe field, to spark collaborations, to forge net-works and build community.Then the creative writing workshops’ goals arethe same as any other BIRS workshop!Yes, but as we noted in our report to BIRS after thefirst workshop, our program is, of necessity, highlyexperimental. In the first workshop we followedthe standard practice of assigning each participantan hour lecture slot. But that didn’t always givepeople the detailed, line-by-line, feedback somehoped for. And a few people read work they’dalready published, so feedback was moot. We foundwe needed to set aside time for other things too.So, for the second workshop we modified the for-mat in various ways.How did you organise the time?Well, a typical day went like this:8–9: Breakfast in Corbett Hall, BIRS’s head-quarters9–10: Reflections: the full group meets to dis-cuss, orally or in writing, issues raised or workspresented the previous day; further ideas andinspirations.10–11 and 11–12: Two presentations of works-in-progress to the full group, followed by discussion.12–1:30: Lunch1:30–4:30: Time free for writing4:30–6: Parallel sessions — as many as anyonewished — on works-in-progress in small groups,two to ten, for line-by-line comments and editing6–7:30: Dinner in the Banff Centre dining hall7:30–9: Discussions of general issues, or publicreadings with participants in the Banff Centre'sworkshop Writing With Style.Tell us about the evening discussions.The first was called, “What, Why, and ForWhom?” It covered a lot of ground, from la-menting math phobia and emphasizing the needfor better science and mathematics education, toconsidering the many forms that outreach canParticipants at the 2004 BIRS Creative Scientific Writing WorkshopVol. 8, Issue 18The Banff Centre, the CMS, and PIMS will hosta 4-day conference bringing mathematicians andartists together to encourage and demonstrate themany exciting connections that link the worldof mathematics to the visual arts, music, sculp-ture, architecture, poetry, computer graphics,theatre, and indigenous cultures.The conference is the first time the verysuccessful international Bridges Conference(http://www.sckans.edu/~bridges/) is comingto Canada, and to celebrate this, one day willbe devoted to the life-long interests and con-nections of the late Donald Coxeter to theworld of artists and the arts, and to ways ofcontinuing and encouraging his legacy.The conference will also be of great interestto teachers at all levels in mathematics.• General Sessions: to introduce new and inno-vative approaches in mathematical connectionsin science and art by inviting international schol-ars and artists as invited speakers.• Special Sessions: the conference encouragesparticipants to contribute to the conference bypresenting their own works in the Special Sessions.• Workshop Sessions: providing opportunitiesfor participants to watch and work hands-on withestablished artists who are crossing the math-ematics-arts boundaries.• Musical and theatrical performances.• Conference Proceedings:  available at thetime of the conference — a resource book andguide to further exploration of the talks andexhibits of the conference.RENAISSANCE BANFFRenaissance BanffA Mathematics-ArtsConference at theBanff Centre, Banff, AlbertaJuly 31 to August 3, 2005http://www.pims.math.ca/RenaissanceBanff/RenaissanceBanff@pims.math.caOrganisers: Reza Sarhangi,Christiane Rousseau,Nassif Ghoussoub, Robert MoodyRenaissance Banff Logo designed byRobert J.

And we lamented the worm in the apple:Proof, A Beautiful Mind and other popular workswouldn’t have been so successful had the math-ematician character been sane.Audiences always prefer demented geniuses, orflawed ones. Not only scientists and mathemati-cians. Think of Amadeus, about Mozart, and allthose films about van Gogh.It’s true, it’s very difficult to portray intellectualcreativity of any kind. But the scientific/mathemati-cal nut is tougher to crack — sorry, wrong meta-phor. I mean, the mad composer or painter or writercan be shown composing or painting or writingmadly, furiously, but in the end he or she producessomething the public can hear or see or read. Whilea mathematician, mad or sane, produces a mysti-fying theorem. But on the other hand, the playCopenhagen was a great success and the novelEinstein's Dreams conveys the scientific creativeprocess in a beautiful way.  And Arcadia, a funnyand chaotic play whose leitmotif is chaos theory,is a modern classic. The mathematical formalism issymbolized in its structure.Using a mathematical structure to talk about math— that reminds me of a sonnet by Edna St. VincentMillay, “Euclid alone has looked on Beautybare.” The poem's strict form mirrors deduc-tive geometry’s austere beauty. “Fortunate theyWho, though once only and then but far away,Have heard her massive sandal set on stone.”Would you say the sonnet form has mathemati-cal affinities?One of us would, the other wouldn't. But that'sa discussion topic for a future workshop. Backto your earlier question: our discussion the lastnight was, “Where Do We Go From Here?”The last night? Then tell us first about the publicreadings.Well, as you know, BIRS is located in the world-renowned Banff Centre. With studios nestled inthe woods, outstanding mentors, excellent per-formance spaces and a fine library, the BanffCentre nurtures aspiring, mid-career, and estab-lished musicians, painters, photographers, writ-ers, and actors. Artists love Banff. And Banffloves the artists: the centre's world-class exhibi-tions, public readings, and performances enhanceBanff’s appeal to tourists year-round. The BIRSleadership hopes BIRS will interact with theCentre. So in organising our workshops, weworked closely with Carol Holmes and EdnaAlford of the Banff Centre’s Writing and Pub-lishing Program. Their “Writing in Style” work-shop and our second workshop took place thesame week. On two evenings, we merged thetwo groups for informal public readings. A fewparticipants in other BIRS and Banff Centre pro-grammes attended too. We hosted an evening ofpoetry, with eleven readers from both groups.They hosted a prose reading evening, with fewerreaders of course, but again from both groups.And were these readings successful?Very. Participants in the two groups met oneanother and some of their conversations contin-ued at meals the next day. Another importantbenefit was the opportunity for writers, in bothgroups, to read their work to and get responsesfrom audiences outside their usual orbits.So where do we go from here?In many directions! Workshop participants planto stay in touch, and to keep each other informedof the progress of their work. We will share infor-mation about publishers and agents. Someone sug-gested we ask BIRS to link our publications to itswebsite. The Mathematical Intelligencer alreadyencourages creative writing in mathematics, but wewant it to do even more. We hope to hold anotherworkshop at BIRS in the future, in close associa-tion with Banff Centre writing programs, and topublish an anthology under their auspices.I can see it now: a hefty tome, the year's BestCreative Writing in Mathematics.Yes, the hottest item in the bookstore, its salestopping the year's best short stories, best es-says, best mystery stories, best political fiction,best non-required reading, best recipes, best sci-ence and nature writing, best spiritual writing, bestsports writing, best travel writing, and best erotica.Hors de doute.

Green and T. Tao, is available athttp://www.arxiv.org/abs/math.NT/0404188.Ben Green (Trinity College, Cambridge)In Spring 2004, while I was a PIMS postdoc in Vancouver, Terry Tao ofUCLA and I published an article about arithmetic progressions of primenumbers. Whilst the article has not yet been accepted for publication bya journal, it does seem appropriate to give a very brief description of theresults and methods in this newsletter.The sequence of prime numbers        has been studied forover 2000 years. The appeal of prime numbers to mathematicians is per-haps that they are extremely simple and natural to define, but it is oftenvery difficult or impossible to prove facts about them. As an example,consider the 250 year-old conjecture of Goldbach, which suggests that ev-ery even number greater than 2 is a sum of two prime numbers. It is easyto verify this for small values (e.g.     ,   	  ) andto come up with heuristic arguments which suggest that the conjecture istrue. So far, however, no-one has been able to supply a proof. The samegoes for the Twin Prime Conjecture, which states that there are infinitelymany pairs of primes which differ by two, such as   and 	 	.Our work concerns arithmetic progressions of primes. The sequence     is an arithmetic progression of five primes, and the se-quence  			k k        is an arithmetic progression of 23 primes, which is the longest currentlyknown (this latter example was discovered on July 24, 2004, by Frind,Jobling and Underwood).Our result is that there are arbitrarily long arithmetic progressions ofprimes. We can actually prove that there is a k-term arithmetic progressionof primes, all of which are at mostkthough this spectacularly large bound (a number with approximatelykdigits) is unlikely to be greeted with much excitement bycomputational mathematicians!We have not really found a new way of understanding prime num-bers. The main advance in our work is a better understanding of arith-metic progressions. A famous result about arithmetic progressions is the1975 theorem of Endre Szemere´di. This states that if A is a subset ofN  f     g with positive density (say A contains one percent of allnatural numbers) then A contains arbitrarily long arithmetic progressions.Unfortunately, this result does not apply to the set of primes since theydo not form a set of positive density. Indeed, the famous Prime NumberTheorem tells us that the number of primes less than N is about N logN .Our main result is a version of Szemere´di’s Theorem in which the setN is replaced by a more general type of set. Very roughly speaking, weshow that if a set S  N is “pseudorandom” then any set containing apositive proportion of S contains arbitrarily long arithmetic progressions.The set S need not have positive density (it can actually be quite sparse).Once this result is proved, one must construct a set S which is ap-propriate for the primes. Simplifying matters somewhat for the sake ofexposition, we take S to be something like the set of “almost-primes”, thatis to say numbers n, all of whose prime factors are at least n . Theprimes form a positive density subset of S, but S is a much more tractableobject than the primes themselves. Indeed by “massaging” S a little bitone can show using techniques of classical analytic number theory, that Sis pseudorandom.In constructing S the authors enjoyed a rather large slice of luck. InMarch 2004 I was visiting Andrew Granville in Montre´al, and I told himabout my work with Terry. At that stage we did not quite understand howto massage the almost-primes in a way that would enable us to prove pseu-dorandomness. Andrew was able to direct us to some recent (as yet un-published) work of Dan Goldston and Cem Yıldırım. Although the workof Goldston and Yildirim concerns a very different problem, it turned outthat a certain lemma in their paper constituted a very good definition of Stogether with a proof that S is pseudorandom.The most original part of our work is the proof of a version of Sze-mere´di’s Theorem relative to an arbitrary pseudorandom set S. The ar-gument is strongly motivated by a branch of mathematics called ergodictheory, which has proved very useful in the study of arithmetic progres-sions since groundbreaking work of Furstenberg in the late 1970s.We prove, then, that any set consisting of a positive proportion of Scontains arbitrarily long arithmetic progressions. Subsequently we applythis to the specific set S discussed above, which is related to the almost-primes. A number of mathematicians have remarked to us that this isprecisely why we are successful – history indicates that isolating proper-ties of the primes themselves is a very tricky business, but here we havebeen able to exhibit the primes as a specific instance of a larger class ofsets (the positive density subsets of S). For exactly this reason, it wouldbe optimistic to expect our methods to shed any light on the Goldbach orTwin Prime conjectures in the near future.Fall 2004 112nd PIMS Crystal Growth WorkshopContributed by C.

TorontoThe National Program on Complex Data Struc-tures (NPCDS) is entering a period of height-ened activity as it evolves collectively as a co-herent network of projects with emerging de-signs for future ambitions. Various opportuni-ties for the involvement of researchers, espe-cially students, include three workshops in July,August and October of this year—where theavailability of funding for student travel sup-port has been announced; a call for proposalsfor inaugural NPCDS workshops—deadline:September 30, 2004; the availability of studentresearch positions at Statistics Canada; joint PDFsat PIMS; planning of the joint NPCDS/SAMSIworkshop at BIRS April 2005; and NPCDS inter-action with SAMSI’s thematic programme on La-tent Variable Models in the Social Sciences.September’s call for proposals will likely bethe last for the current funding cycle of NPCDS.While NPCDS will continue to support and ad-vance existing projects, in time broader long termstrategies will emerge that are aimed at NPCDSrenewal as a network. While these will evolveon multiple fronts, the success of the NationalProgram depends on the active involvement ofstatisticians from a variety of sectors acrossCanada. Those interested in providing input onimportant directions for the program are wel-come to do so by contacting Jamie Stafford(stafford@utstat.utoronto.edu) or any memberof the Scientific Committee. The NPCDS is ajoint initiative of the Statistical Sciences Com-munity of Canada and the nation’s three Math-ematics Institutes.

About 30 seniorundergraduate students from all over Canada spent Friday at Simon Fraser University and Saturday atthe University of British Columbia. At SFU students were welcomed by Jonathan Driver (Dean ofGraduate Studies) and Rolf Mathewes (Associate Dean of Science). Students heard presentations fromrepresentatives from various graduate programmes, notably Pure Mathematics, Applied Mathematics,Computer Science and Statistics. The Universities of Alberta and Calgary also had faculty representativesat the SFU event. Students had the opportunity to see the campus and various research labs; there was alsoample opportunity to meet informally with faculty members and graduate students.PIMS at the University of Victoria hosted the second part of the Graduate Information event.  Afterarriving on Sunday, the students were free to explore the city. In the evening, a reception was held at theExecutive House Hotel, host hotel for the participants. There, the students were able to meet informallywith faculty and graduate students from the Departments of Mathematics and Statistics, Physics andComputer Science.On Monday, the students came to the University of Victoria campus where Aaron Devor (Dean ofGraduate Studies) welcomed them. Then they heard presentations from faculty and graduate students ongraduate degree programs in pure, applied and discrete mathematics, statistics, physics and astronomy,and computer science.  The participants ended their day at UVic with a brief tour of the campus.We are grateful for the generous support provided to this event by the participating universities anddepartments, as well as for the efforts of faculty members, graduate students and local PIMS staff.Young Researchers’ Forum inMathematical & StatisticalSciencesUniversity of AlbertaMarch 27–28, 2004This was the first research forum organized for thegraduate students of at the Universities of Albertaand Calgary.  Twenty-five graduate students fromCalgary and thirty-eight graduate students fromEdmonton registered for this event. Ten of thesestudents presented their research work covering top-ics from pure and applied mathematics and statis-tics. These presentations were well received by theirfellow graduate students at the forum.  The participants had the opportunity to learnabout and discuss the research done at both univer-sities.  A general discussion was arranged for feed-back at the end of the forum. A second researchforum is being considered for next year at BIRS.On May 14, 2004, the Pi in the Sky EditorialBoard met at BIRS to define editorial policyand procedures.The following statement describes the in-tended audience: Pi in the Sky Magazine isprimarily aimed at high-school students andteachers, with the main goal of providing acultural context/landscape for mathematics.It has a natural extension to junior highschool students and undergraduates, andarticles may also put curriculum topics in adifferent perspective.Pi in the Sky can be downloaded for freefrom www.pims.math.ca/pi.If you are interested in submitting an ar-ticle please contact pi@pims.math.ca.The new editorial board is:Editor in Chief: Ivar Ekeland (UBC)Managing Editor: David Leeming (UVic)Editorial Board: Len Berggren (SFU), JohnBowman (UA), John Campbell (ArchbishopMacDonald Academic High School,Edmonton), Florin Diacu (UVic), SharonFriesen (Galileo Educational Network,Calgary), Dragos Hrimiuc (UA), KlausHoechsmann (UBC), Wieslaw Krawcewicz(UA), Michael Lamoureux (UC), MarkMacLean (UBC), Alexander Melnikov (UA),Volker Runde (UA), and Wendy Swonnell(Lambrick Park Secondary School, Victoria).Editorial Coordinator: Heather Jenkins (PIMS).The next issue will be out in the fall of2004.

Thepublic lecture, A Community of Learners: Prepar-ing Students for University and for Life, was givenby Elaine Simmt (Faculty of Education, U of A).The panel discussion was entitled Reflections onSchools Mathematics Curriculum.The 6th Annual PIMS Elementary Grades Mathematics Contest(ELMACON) was organized by Shelley Alvarado, Cary Chien, Olga Ger-man, Klaus Hoechsmann, Heather Jenkins, Ilija Katic, Joshua Keshet, FannyLui, Natasa Sirotic and Elizabeth Towers.  The contest ran smoothly withabout 50 on-site volunteers including Jerry Chien and Sylvia Chan.  A totalof 244 students competed: 75 in Grade 5, 99 in Grade 6, and 70 in Grade 7.Next year, ELMACON will take place on April 30 , 2005.The list of winners of the 2004 contest can be found athttp://www.pims.math.ca/educations/2004/elmacon/.

The students had a background of at least three years of high school mathematics but had not yet completedhigh school. Admission was competitive, based on an assessment both of ability in mathematics and enthusiasm for anintensive mathematical experience. Many students stayed in UW residence halls.The SIMUW programme was organized by four UW faculty members: Ron Irving, Sándor Kovács, James Morrow, and Paul LePore. Six mathema-ticians from UW, Microsoft, and the University of Chicago served as the instructors. In addition, another eight mathematicians and scientists from UWand elsewhere participated as special lecturers.The programme was divided into two-week blocks, with two instructors for eachblock. During four of the five weekdays of each week, the students met with one of theinstructors in a morning session and the other instructor in an afternoon session. Duringthese sessions, students grappled with mathematical problems that are designed to bechallenging yet ultimately accessible. The instructors lectured to a limited extent, in orderto provide necessary background, but the emphasis was on giving the students theopportunity to tackle hard mathematical problems in collaboration with the staff.A special programme was arranged for the remaining weekday of each week. In themorning, a speaker from the campus or the region discussed the role mathematics playsin his or her work. The afternoon session either featured a second speaker or consisted ofa special activity or field trip related to mathematics.For more information please see http://www.math.washington.edu/~simuw/.Participants in SIMUW 2003JUMP Comes to PIMSJunior Undiscovered Math Prodigies(JUMP) is a volunteer based charitableorganisation that was founded by JohnMighton in 1998.  Its purpose is to providefree tutoring in mathematics to elemen-tary students, especially those of disadvan-taged background.  Over the past fiveyears, John Mighton has observed manysurprising improvements in mathematicalaptitude in students enrolled in JUMP, particularly in studentswith severe learning disabilities.On April 26, 2004 John Mighton gave a public talk atUBC: The Myth of Ability: Nurturing Mathematical Talent inEvery Child.  He spoke about the method of instruction usedin JUMP and about why he thinks the method works withstudents who have traditionally struggled with math.  Thistalk will soon be available on the PIMS website in Realvideoformat.On July 29, 2004 John returned to PIMS-UBC to give afollow-up session that covered the JUMP methodology withspecific examples from the new workbooks.  He also spokeabout how one could go about implementing the programme.John Mighton is a mathematician and a Governor General'sAward-winning playwright.For more information about JUMP please see http://www.jumptutoring.org/.PIMS is  planning future collaborations with JUMP.31st BC Colleges High SchoolMathematics ContestUniversity College of the Cariboo,Kamploops BC May 7, 2004Contributed by Rick Brewster, University College of the CaribooThe BC Colleges High School Math-ematics Contest  was a great successagain this year.  The enrichment talkwas given by Frank Ruskey (UVic).His talk was well received by the stu-dents, and his “Venn knot” was agreat design for the T-shirts.  Duringthe morning session with Frank, UCCfaculty and high school teachers  en-joyed a great discussion on teachingmathematics and the transition fromhigh school to university.While the contest was being held at UCC, one of the UCC faculty members, JimTotten, who has been a driving force behind this contest for many years, travelled toNorthwest Community College in Prince Rupert.  There he assisted Mona Izumi withhosting the contest for the first time in Prince Rupert.  Mona is the sole mathematician atNWCC in Prince Rupert, making it difficult for her to launch the contest in Prince Rupert.The students in Prince Rupert enjoyed Jim's collection of mathematical puzzles and games.The BC Colleges’ High School Mathematics Contest has always been about participa-tion and not competition.  In this respect it is a wonderful mathematics outreach activity.John Mighton(JUMP)At the BC Colleges High SchoolMathematics ContestSouthern Gulf Islands, British ColumbiaPender Island in the foregroundPhoto by Manfred TrummerPIMS Contact ListDirector: Ivar Ekelandt/ 604.822.9328 f/ 822.0883 e/ director@pims.math.caDeputy Director: Manfred Trummert/ 604.822.3922 f/ 822.0883 e/ deputy@pims.math.caSFU Site Director: Manfred TrummerAdmin.
