Networks and graphs are all around us, even if we don’t notice much: roads, the electricity grid, the airline routes, the Uber taxis in Cape Town, even your group of real and Facebook friends – they’re all networks involving, if you bring it down to the basics, some nodes and links between these nodes. Scientists have been getting more and more interested in these networks and especially in classifying their ‘shape’. Are all networks the same? Are there ‘universal’ types of networks? Is a Facebook-friend network the same shape as an electricity grid network? How do networks evolve? What can we do with networks? These are some of the questions we discussed at our ResearchNight.it led by Dr Hugo Touchette.
Dr Hugo Touchette is Chief Researcher at the National Institute for Theoretical Physics, Stellenbosch. He moved there in 2013 after spending 9 years in the School of Mathematical Sciences, at Queen Mary University of London. He holds a PhD from McGill University in Canada, where he is from.
