Byrne September 11, 1990 This report on my June 1990 trip to Europe will be of interest to those readers who would like to follow some of the technical and non-technical trends in Europe. The purposes of the trip were to: Visit ETH, Zurich and to give a seminar there on the differential equation solvers VODE and VODPK, which were written by Peter Brown, Alan Hindmarsh, and me. Visit the Konrad Zuse Zentrum in West Berlin and to speak there about recent work with VODPK. Attend and participate in the Vienna Scientific Computing Conference, which was in the honor of Hans Stetter on the occasion of his sixtieth birthday. Attend and participate in the 1990 Numerical ODE (ordinary differential equation) Conference at the Helsinki (Finland) Technical University. Of course, there were less technical reasons for this particular trip to primarily German speaking Europe. I wanted to see first hand the changes, to get a sense of their potential impact, and to visit family friends near Bonn. To prepare for this I had taken a few lessons in German, which were very helpful. Except for the trip from Vienna to Helsinki, my travel was by train, on which, quite logically, German was the usual language. Zurich Zurich is a compact, clean city in a beautiful setting of a valley surrounded by low mountains and the city, a lake and river in the valley. During my June 5-8 visit to ETH (Eidgenoessische Technische Hochschule, the Swiss Federal Institute of Technology Zurich) had several visitors from the U.S. Paul Saylor and Bob Skeel both from the University of Illinois, Champaign-Urbana were there. Bob was visiting Paul on his way to the conference in Vienna and Paul was there for the summer at the invitation of Walter Gander. Bob and Paul are interested in iterative linear algebraic methods in the setting of stiff ODE solvers. Some of the technical work at the Applied Mathematics Seminar involves a parallel implementation of waveform relaxation. The latter work is being done by Bert Pohl, a student of Rolf Jeltsch. Rolf was my host and now occupies the chair formerly associated with the late Peter Henrici. Rolf struck me as being interested in long-term developments, good access to the computer network from workstations, and as having the kind of rapport with his students that would be envied by many American professors. In Zurich, I was determined to try to use my limited knowledge of German. My attempts led to conversations with some very marvelous people and made the trip more enjoyable. It was my first adventure in laguagae immersion with no alternative. It was well worth the effort. West Berlin At the Konrad Zuse Zentrum - Berlin (ZIB) the recent changes in East-West relations were quite obvious. About half of my audience had come over from East Berlin. In the city itself, there were many people from Eastern Europe shopping and traveling around the city by bus. Peter Deuflhard, the President of ZIB and my host, indicated that activities at ZIB include work on multilevel methods, theoretical and practical studies of Broyden-like methods and their significance in iterative methods in linear algebra, reacting chemical systems (including 1-D and 2-D combustion) and, of course, extrapolation methods for ODEs. Symbolic comput- ing is also an area represented by a high level of interest. Peter provided me with the opportunity to talk with Ulli Nowak and several other members of the technical staff about mutual interests. At the time of my visit, June 11 - 13, Berlin was still divided and there were but two border crossing points for Americans - Checkpoint Charlie and Friedrichstrasse. The border no man's land was apparent to even the most casual observer. The contrast between East and West Berlin was perhaps more striking than an East German had told me it would be. In the East, quality of the automobiles was poor and they gave off strange sounds and a stench, the apartment complexes were stark, and lines were evident. West Berlin was clean and gave off an eerie feeling, perhaps from its long-term isolation. There were some reminders of the devastation of World War II, as well as post war prosperity. My growing, but limited German vocabulary was very helpful in Berlin. Vienna The Vienna Conference on Scientific Computing was well-organized and had about 100 participants representing from 20 countries and featured over 60 papers, all contributed. This conference was held June 14 - 16 and its central themes included Runge-Kutta methods for ODEs, DAEs (differential-algebraic equations), and software issues. Owing to the number of days of the conference and the number of papers, there were usually two parallel sessions throughout the day. Some of the events associated with the conference reflected Hans Stetter's stature and the Viennese culture. The opening of the conference included speeches recalling Hans' accomplishments and his several roles in his field of study, the University, the city of Vienna, and Austria. Several bouquets of flowers were presented to Frau Stetter, a charming, gracious lady. The biggest surprise for me was the reception at the Vienna City Hall. The ballroom was lighted by two very large crystal chandeliers and was decorated with coats of arms associated with Austria. A representative of the mayor of Vienna gave a speech both welcoming the international contingent and the importance of some of Hans' work. John Butcher gave a very nice, serious speech recounting some of Hans's technical accomplishment and indicating his international influence. The speeches were followed by an exceptionally good buffet dinner and American jazz played by a three piece combo. Some of us enjoyed dancing to the good music and in the motion picture-like setting. In short, the reception was a far cry from bad beer in a plastic cup and waiting for a chance to leave graciously. It should be noted that it started punctually and ended punctually, as one might guess. There was also a tour of Stift Melk, a beautiful abbey on the Danube and some of the nearby historic villages. The chapel in Stift Melk had been recently rennovated and was breathtaking. In one village, Richard the Lionhearted had been held for ransom after one of the Crusades. The tour was concluded with a visit to a Heuriger, a Viennese wine house that sells its own new wine, serves hearty rural food, features folk music, and a very happy atmosphere. At this party, it was my privilege to recall some of the humorous aspects of the 30 or so years that I have known Hans. Hans in turn had the crowd sing Happy Birthday to me, since the party was on my own birthday. It was a marvelous way to celebrate a birthday. Hans Prochaska of Hewlett Packard and his wife were the host and hostess for this party, which was sponsored by H-P. Vienna is charming and beautiful. It is very easy to get around the city by public transit. The architecture is varied and beautiful and ranges from an ultra modern all glass building to historic St. Stephen's cathedral, which is just across the square. Vienna is clearly a crossroads, as can be attested by the many languages spoken on its streets and in the shops. It is hardly a surprise that many Europeans rank Vienna high on their list of vacation spots or that its palaces are so frequently visited. The organizers for the Vienna conference were Christoph Ueberhuber, Richard Weiss, and their colleagues from the Technical University of Vienna. It was well very well done. Helsinki The 1990 Conference on the Numerical Solution of Ordinary Differential Equations had a strong representation from both Eastern and Western Europe, reflecting Finland's international position. During this June 18 - 22 conference, there were about 85 presentations in three categories: invited, highlighted, and contributed. The invited speakers were: John Butcher Ernst Hairer S. Yu Pilyugin Florian Potra and Bob Russell. The highlighted speakers were: Rudolf Scherer R. P. Fedorenko K. F. B. M. Kraaijevanger Moody Chu Klaus Ulrich Robert Corless Roger Alexander Kevin Burrage Des Higham and George Byrne. The themes of this conference also included Runge-Kutta-type methods, and DAEs. Not surprisingly, another of the themes was { waveform relaxation (also known as Picard-Lindelof iteration). Others were boundary value problems, continuation, control problems, and a good dose of classical analysis. As last year in Britain, the large number of papers on Runge-Kutta methods and DAEs was agaom evident. Olavi Nevanlinna was the conference organizer with strong support from Ben Leimkuhler and others from the Technical University of Helsinki. Some non-technical highlights were a Finnish sauna evening and a tour. A sauna is an experience that is hard to describe, worth trying once (at least), and a social event that is remarkable. Before the sauna, I asked a desk clerk what I needed for a sauna -- swim trunks, perhaps. Her reply was, "Well, I suppose you could take the towel from your room." After the fact, a Swedish colleague said that the Finns do it all wrong by having separate sauna cabins for the men and for the women. Our tour included a visit to Fiskars, the home of the cutlery firm whose scissors and knives are respected by housekeepers throughout the world. The visit to that village was followed by dinner at a Baltic inlet and coffee at outdoor restaurants. Finland reminded me very much of the lake country in Northern Minnesota -- pine trees, stands of birch, clean air, and lots of water. On June 22, quite a few of us attended the midsummer's night festival on a small island in Helsinki's harbor. There were people demonstrating crafts, good sausages, and the annual bonfire made of old canoes and small evergreen trees, with songs and a ceremonial wedding. Perhaps most striking was the 10 kilometer walk back to the campus in the bright midnight twilight. A fitting way to say farewell to a hospitable country. General Comments, Observations, and Personal Opinions I greatly believe in conferences and foreign travel and recommend both. They are broadening, an interesting way to meet people and to learn. The generosity and kindness of people is generally underestimated and the experience of learning that is well worth substantial effort. ^By way of an example, some East and West Berliners in my train compartment gave me beverage, a thick cheese sandwich, and chocolate for lunch, although three was a dining car on the train. We joked in a mix of German and English (with frequent references to my pocket dictionary and phrase book). We spoke of the political changes, the U.S. and shared a day of our lives. Yes, a smile and humor in good taste can be contagious.| The conferences described above were run and organized professionally, with grace, good humor, and no obvious hitches. It pleased me to see such strong representation from Eastern Europe, especially in Finland. There was some good natured joking between East and West and I was pleased to see for the first time some correspondents of twenty or so years. Most of the speakers at the conferences were sincere, gave presentations much like one another, and believed that their work is significant. They are unquestionably bright, articulate, and interesting people. Yet some of the computational methods proposed can not compete with existing methods, at least on realistic problems. More than a few speakers tended to face the projection screen while speaking, used view graphs that are illegible in the first row of the audience, mumbled, spoke in a monotone voice, read their presentations verbatim, or did not seem interested in their own work. Moreover, a number of the presenters assumed that the audience knew as much about some isolated topic as they did and, as a consequence, lost much of the audience in the first few minutes of the presentation. If in our own specialties such observations can be made, how can we expect to convey our techniques, methods, software, and ideas to a broader user audience? How can we convince funding agencies and politicians that our field is important? Why do we expect others to follow us in our field of endeavor? How can we sincerely speak about education and classroom performance? The above in no way detracts from the effort of the speakers to present their work in English, a difficult language, at best. Precisely the same observations applied to the SIAM meeting in Chicago! I would like very much to see the introduction of awards for best presentation at significant conferences. Technical societies in other fields have done this for a long time. Now it is time for us to do the same. If this is showmanship or public relations, fine. Let's do it. If you would like to try a field test, pick an arbitrary lecture at a large applied mathematics conference, stand in the back, and watch the audience. Now, estimate the percentage of the audience who are asleep, reading, talking, or otherwise not following the presentation. The results are usually astonishing. ------------------------------ From: Ed F.
