Synchronization
Synchronization is a phenomenon which has received a lot of attention in the last few decades. It is the mechanism by which a group of individuals that go through some periodic motion begin moving through the same parts of their cycles at the same time.
Financial Economics: Informal Collaboration, Networks, and Gender
How is scientific knowledge created? Are there patterns and special characteristics behind the flow of scientific knowledge? In this article I will guide you through my research work and try to give some answers to these questions!
"Look it up on the Internet!" - How Web Search Works
In this article we will have a look at how search engines work. What happens when you type the query in the famous, almost magical, Google's white page? And what does it have to do with networks?
Artificial intelligence for two-year olds
One of my biggest pleasures of life is to watch my children learn things that we take for granted. Some months ago my daughter learned the skill of jumping. I asked myself how to teach a machine to do this.
Complex networks
Have you ever wondered what mathematicians mean when they talk about mathematical models of real-life phenomena? And what can such a model tell us about the network-phenomenon we are studying?
What does your Facebook network look like?
Have you ever wondered if you can visualise your Facebook network? And what do these networks have to do with mathematics?
An elephant in the room
Do you see the elephant in this picture? This is not so easy for a computer, even if it is "intelligent".
Traffic congestion: Braess' Paradox
Can you imagine that the, seemingly innocent and quite natural, idea to build more roads in order to solve the traffic problem can be sometimes quite a bad idea.
From Atoms to Reaction Networks
Have you ever thought about a relation between chemistry and networks? Already from school courses we get the feeling that there is some interplay between mathematics and chemistry. In this article we will see how graph theory can help us understand the way chemical reactions occur.
Traffic congestion: Optimal tolling schemes
Congested road networks are a big problem in many countries. Building more roads is not always the best solution to solve this issue. One of the reasons for this is that drivers behave selfishly
