Das Forum in Bildern

Posted 3 October 2013 by Marlene Knoche

Da ich neben meiner Liebe zur Informatik und dem Bloggen auch eine gewisse Affinität habe, Bilder von meiner Umgebung zu zeichnen, habe ich auch ein kleines Reisetagebuch für das Forum angelegt und einige schöne und für mich besonders wertvolle Bilder zeichnen können. Viel Spaß beim ansehen! ... Read more

Die drei Künstlichen Intelligenzen

Posted 2 October 2013 by Tarek Richard Besold

Dabbala Rajagopal ("Raj") Reddy ist Turing Preisträger - und einer der Experten für Künstliche Intelligenz (KI) unter den Laureaten. Entsprechend ging es in einem Gespräch, welches ich im Rahmen des Heidelberg Laureate Forums 2013 mit ihm führen konnte, nicht nur um Chancen und Entwicklung der digitalen Globalisierung und des Internets, sondern auch um Geschichte und Zukunft seiner "Heimatdisziplin". ...

Farewell to Heidelberg, plus N-Dimensional Volumes

Posted 1 October 2013 by Dana Mackenzie

Two days ago the Heidelberg Laureate Forum came to an end, with a grand farewell dinner at Heidelberg Castle. Back in July, when I was invited to join the blog team for the Heidelberg Laureate Forum, I didn't accept immediately. I was busy, and a week in Germany would definitely affect my writing schedule. For several days I sat on the fence, but what finally decided me was... the fact that we would have the closing dinner in a castle!... Read more

Research At the Interface Between Disciplines

Posted 1 October 2013 by Guest blogger

Amanda Randles, HLF13 participant: Throughout the Heidelberg Laureate Forum, there was a strong emphasis on the role interdisciplinary research may play in the future of computing.  It was the focus of lectures such as Stephen Smale’s chalk talk on protein folding  and Richard Karp’s inspiring presentation titled "The Computational Lens on the Sciences".  As I am just starting out in my career and looking to pursue research at the intersection of computational and biomedical research, I was excited to see...

Dealing with the unexpected: William Kahan and the need for graceful exits

Posted 1 October 2013 by Markus Pössel

In a previous post, I took a trip down read-only memory lane with William Kahan. On the same trip, Kahan told me about his first commercial programming job. The software was meant to aid the operations of Trans-Canada Air Lines (now Air Canada) by helping it save on, wait for it: telegraph charges. To this end, it was to keep track of the seats available on various flights, the better to coordinate reservations (presumably cutting down on unnecessary inquiries by... Read more

Ende ohne Schrecken: William Kahan und der geordnete Rückzug von Computerprogrammen

Posted 1 October 2013 by Markus Pössel

In einem früheren Beitrag war ich mit William Kahan in die frühe Neuzeit der Computertechnik zurückgereist. Dabei hatte mir Kahan auch erzählt, wie er das erste Mal ein Software für eine Firma geschrieben habe - ein Programm nämlich, das Trans-Canada-Airlines (heute: Air Canada) dabei helfen sollte, Telegraphiekosten zu sparen, indem es Sitzplatzreservierungen auf diversen Flügen überwachte und koordinierte. Derjenige Teil des Programms, der sich direkt mit Sitzplätzen beschäftigte, sei dabei das geringste Problem gewesen. Knackpunkt war stattdessen, dass der Computer,... Read more

Voevodsky’s Mathematical Revolution

Posted 1 October 2013 by Julie Rehmeyer

On last Thursday at the Heidelberg Laureate Forum, Vladimir Voevodsky gave perhaps the most revolutionary scientific talk I’ve ever heard. I doubt if it generated much buzz among the young scientists in advance, though, because it had the inscrutable title "Univalent Foundations of Mathematics," and the abstract contained sentences like this one: “Set-theoretic approach to foundations of mathematics work well until one starts to think about categories since categories cannot be properly considered as sets with structures due to the required...

I remember – A week gone – A life time spent

Posted 30 September 2013 by Guest blogger

Bushra Anjum, HLF13 participant: As I sit now in my faculty office waiting for my class to begin in an hour (I am a faculty member in Lahore, Pakistan) I think about the many fond memories I have made in the last 7 days in Heidelberg. I remember sitting with Sir Michael Atiyah as he explained the very first computers were made out of timber, and as the wood is self lubricating, it was in some ways a better substance... Read more

A trip down read-only memory lane with William Kahan

Posted 30 September 2013 by Markus Pössel

I've already written here about the weirdness of certain floating point operations - the case of the misbehaving Excel spreadsheet in particular - taking my cues, and my examples, from floating point pioneer William Kahan (notably this set of slides [PDF]). Before writing about the dire consequences of programs not equipped to handle such mistakes - which I will do in a later post - there is another issue that figured largely in my interview with Kahan on last Tuesday...

Balance – How to develop a research career and a growing family?

Posted 30 September 2013 by Beatrice Lugger

How to find a balance? How to deal with career and kids? Matthias Hagen from Weimar University, Germany, had the idea for this workshop: “Balance – How to develop a research career and a growing family”. Avi Widgerson, Nevanlinna Laureate, and about 70 participants attended this. Especially the young researchers have to deal with career, friends and family, time for your own. They are in their ‘rush hour of life’, as Matthias named it. The best contribution to the discussion... Read more
