## NETWORKS goes to school 2021 – **Online**

It is almost time for the annual masterclass on network science organized by the NETWORKS program! This masterclass on the mathematics of networks is held in English and hence suitable for international schools as well.

The masterclass this year will be held in February in the form of three independent online classes of two hours each. There is no overlap between these three events, feel to free to register for as many as you want! The schedule with a short description of the topics discussed can be found below:

**Monday 8th of February 14:00 – 16:00: Janusz Meylahn – Complex networks – Learning how synchronization work**

In this talk you will have a glimpse in how synchronisation works. Synchronisation is the coordination of events to operate a system in unison. Simply put, multiple parts work together to produce one whole. Think of phenomena like fireflies flashing in synchrony, neurons ringing in the brain, the gravitational synchronisation of meteors** **or an audience clapping after a concert;** **

**Wednesday 17th of February 14:00 – 16:00: Rens Kamphuis – Graph theory – Finding the o**

*ptimal route in a road traffic n**e**twork*In this talk you will see how graphs can be used to represent networks and how algorithms can be constructed to solve questions about networks. For instance, what is the shortest route from one location in a network to another? This is a question that we ask our favourite route planner on a daily basis.

**Friday 26th of February 14:00 – 16:00: Youri Raaijmakers – Queueing theory – Preventing queues growing large **

In this talk you will see how a mathematical model of a queue can be constructed and analyzed. Some typical everyday examples of queues can be found in supermarkets, industrial production systems and hospitals. In a supermarket customers arrive to the counters, they may have to wait in the queue until their turn comes, they are served and then leave the supermarket. But an important question is, can we change the policy serving the customers to serve them faster?

If you would like to attend one of the online masterclasses please fill in the registration form.

Each event will consist of a lecture and an exercise session.

The aim of the events is to introduce secondary school students with an interest in mathematics to mathematics education at a university and to provide them further deepening in their mathematical knowledge. The previous masterclasses “NETWORKS goes to school” were a big success. All the material will be gathered in a self-contained booklet which can be used after the masterclass by teachers in the classroom or by students who want to have a glimpse into networks science! The booklet will be distributed to the students at the masterclass. The material from the previous masterclasses can be found below:

### About the NETWORKS program

NETWORKS is a 10-year program funded by the Dutch Ministry of Education, Culture and Science through the Netherlands Organization for Scientific Research.

NETWORKS is hosted by four research institutions:

- University of Amsterdam (UvA)
- Eindhoven University of Technology (TU/e)
- Leiden University (UL)
- Center for Mathematics and Computer Science (CWI)

The program started in the summer of 2014 and covers a broad range of topics dealing with stochastic and algorithmic aspects of networks. The aim of the program is to address the pressing challenges posed by large-scale networks with the help of stochastics and algorithmics. The focus is on modelling, understanding, controlling and optimizing networks that are complex and highly volatile
