Human-Centred Computing News

In recent years IBM have regularly invited a group of Warwick computer science students to an 'open day' event held at
their research centre at Hursley. A couple of weeks ago a coach-full of our students (from 1st years to 4th years) attended this year's event. One of those attending, Alex Wilson, picks up the story ...

"After arriving in Hursley we were shown around the beautiful grounds of Hursley House before being introduced to IBM staff and facilities. The Galileo Centre, where we spent most of the day, was filled with interesting exhibitions and demonstrations of technology such as facial profiling and uses of RFID tags. The staff gave us presentations on current technologies and uses, such as in the SMARTer planet scheme – including one employee who had integrated public monitoring with his house through Twitter! During lunch we were able to have personal chats with IBM’s Master Innovators, the people who design the new innovations in technology.

The last part of the day was splitting into groups and working on our own “innovations” – we gave a presentation on uses and how we’d implement it to the rest of the students who came and IBM’s own panel of judges. The winning team received iPods as prizes. The entire day was very fun, interesting, and well worth doing again. A big thank you to IBM for their time and hospitality!"

Last week (17th January 2011) saw the publication by Birkhäuser of the Proceedings of a major conference held in 2009 in Potsdam and Szczecin in honour of Hermann Grassmann. The major organiser was Hans-Joachim Petsche (Potsdam) but Steve Russ was a co-organiser, along with Jörg Liesen (Berlin), Albert C. Lewis (Austin, Texas) and Franco Ferrari (Szczecin, Poland). In November 2010 the conference was the first-time winner of a prize awarded by the Brandenburg state for 'Innovative and/or exceptional events'.

Hermann Grassmann was author of a work 'Extension Theory' (1844 and 1862) which contained much of the theory of vector spaces and linear algebra in a remarkably abstract and modern form which was a forerunner and direct influence for the vector and tensor calculus developed later by Gibbs, Heaviside and others, on Clifford algebras and on the differential forms of E. Cartan. Several papers at the conference testified to the continuing influence and fruitfulness of Grassmann's ideas for mathematics and computing, especially for the visualisation of crystallographic structure and to geometric algebra computing.

The conference saw the publication of an English translation of Petsche's biography of Grassmann for which Steve Russ was a consultant. Steve was a co-editor of the Proceedings volume to which he also contributed a paper 'Concepts and contrasts: Hermann Grassmann and Bernard Bolzano'.

The Mathematical Association of America has awarded its 2011 David Robbins Prize for the two papers: “Overhang” by Mike Paterson and Uri Zwick (Tel Aviv) and “Maximum Overhang” by Mike Paterson, Yuval Peres (Microsoft), Peter Winkler (Dartmouth), Mikkel Thorup (AT&T) and Uri Zwick.

The prize, presented on 7 January 2011 at the AMS-MAA Joint Mathematics Meetings in New Orleans, is given every three years for papers reporting on novel research in algebra, combinatorics, or discrete mathematics. Both papers appeared in 2009 in the American Mathematical Monthly. (The first of these had already won a 2010 Lester Ford Award of the MAA.)
