Working with some bright undergraduates, we submitted a paper to the 11th Workshop on Algorithms and Models for the Web Graph (WAW’15). It is a pity I cannot make it this year owing to other responsibilities, especially since I have never been to the Netherlands. I haven’t missed WAW for many years. In fact, I have… Read More The robot crawler number of a graph
Today is Ryerson’s Science Convocation, so I thought I would just post the convocation address I gave in 2013. It was such a memorable day, and I look forward to today, despite the stormy weather. 2013 Science Convocation speech Chancellor Bloomberg, President Levy, Provost Lachemi, Dean Coe, other VIPs, members of the Faculty of Science—proud… Read More Convocation speech
At a nice meeting here in beautiful Charlottetown. After some rain on Saturday, it is now gloriously sunny. The Canadian Mathematical Society summer meeting is one of the largest meetings of mathematicians in Canada. There are public lectures, various keynotes, business meetings, and the scientific session. Our session is on Graphs, Hypergraphs, and Designs. It… Read More CMS meeting in Charlottetown and CanaDAM at Ryerson
We had another successful meeting of Graph Searching in Canada (GRASCan) this last weekend, with about 15 participants from across Canada and the US. GRASCan was held at Universite de Montreal, co-chaired by Gena Hahn and Ben Seamone (I was a co-chair, but did little of the organization). There were talks on graph burning, the… Read More Burning, cats, and zombies: a recap of GRASCan 2015
When visiting the Curie Museum in Paris this May, I became aware that much of Marie Curie’s later work was devoted to the medical uses of radiation. Here was one of the most brilliant scientists of all time, two-time nobel prize winner, with a clear view towards the applications of her theoretical work. While I had… Read More Mind and action
We have been taught since we were children not to disrupt the world around us. Keep quiet… Don’t make waves… Don’t start fires… What would you do, however, if you were encouraged to set fires? That is, burn things down as quickly as possible. It may seem like an odd question, and such thoughts in real… Read More How to burn a network
A horde of ravenous zombies descends on a sole survivor loose in a ravaged city, filled with deserted streets and no help in sight. The survivor happens to be a Mathematician, and so has no weapons to use other than his mind. He has, therefore, no choice but to make a run for it. Which way… Read More Zombies vs Mathematicians!
